Chapter IV: OF MEASURES THAT WILL BE EFFECTIVE.--The evil must be fought in (2)

Having occupied the professorship at Jena for seven years on a salary never exceeding one hundred thalers, and after declining an invitation to Prague, Schmidt in 1855 accepted the appointment of Professor of Zoölogy in the University of Cracow. The conditions at this institution were quite different from those which had surrounded him at Jena. He received more liberal allowances than had been granted him there; but political affairs were disturbed, and he withdrew in 1857 to become Professor of Zoölogy and Comparative Anatomy, and eventually rector, at Grätz. Here he spent the fifteen most enjoyable and most fruitful years of his life, of which his son, Erich Schmidt, has given, in his memorial address, a most pleasant picture. "In the magnificent scenery," he says, "among which he often wandered with his growing children, with warm-hearted men around him, sure of the increasing affection and capacity of his students, he reached his culmination as a naturalist and as a man. He was active in every direction. The university was in a very promising period of its career. A medical faculty was required, and that magnified his function. He also represented his department in the Johanneum, and presided over the museum. He went every year to Dalmatia while he was composing his monograph on the sponges, and made experiments in their artificial cultivation, being given one year a small war steamer at his disposal. These journeys were doubly enjoyed when Franz Unger went with him to Lesina or to the Ionian Islands. He and the great botanist had a close community of interests, and it was an inestimable privilege, during the great scientific crisis, to stand shoulder to shoulder with an older man, who to power of following philosophical intricacies united the habit of the most exact research with finely trained effort and suggestive intuition. Together the two devoted themselves to the study of Darwinism, at first opposed to it, as is shown by one of Schmidt's printed essays, but soon becoming impressed with the conviction that all scientific progress was connected with that revolution, and finally Schmidt gave all his energy to the advancement of it. As Rector Magnificus--the first Protestant to wear the golden chain at an Austrian university--he declared himself, in his inaugural address, for Darwinism with a resoluteness peculiar to him, and neither the silly demonstrations of the theological students nor the wrath of Cardinal Rauscher could intimidate him from the vindication of free investigation.... The rectoral year 1865-'66 was also the year of the Austro-Prussian War, and he now proved that the rashly progressive man to whom the whole clash of opinions was a bath of steel also possessed a considerable measure of self-control. He bore himself correctly in every sense in his difficult position, and, without turning his back upon his native Prussia, he so completely devoted himself to the care of the wounded as to receive a note of thanks from the General Archduke Albrecht. Having been chosen a deputy to the Landtag, his voice was always heard in favor of the Liberal side. He served indefatigably in the communal council and the school board. The Protestant communes depended upon him as one of their most effective champions, even to the end of the partisan contest. Besides all this many-sided scientific and public-spirited activity, Schmidt had time to describe the lower animals for Brehm's _Thierleben_, and to write a number of popular treatises. A lively social disposition bound him to numerous colleagues, and on the whole he felt so much at home in Grätz, especially after he had a new institute and a share in the direction of a zoölogical station at Trieste in prospect, that he had no thought of a change. He declined invitations to Marburg and Dorpat. He was always favored by the Government, and kept the marks of its consideration faithfully in memory."

Ludwig von Graff describes three plainly marked periods in Schmidt's scientific career. The first, the beginning of which coincided with his entrance into his scientific professorship, was characterized by his labors on the _Turbellaria_, from which he was only occasionally diverted during his residence at Jena and Cracow. "The observations on infusoria, radiates, and tapeworms, the structure of the annelids and the development of the mollusks, the descriptions of new amphibia, and the important discovery of the crustacean nature of the peltogasters, were, we might say, only rests in the uninterrupted course of the _Turbellaria_ studies; and that Schmidt was constantly returning to them was not merely because particular interest had been devoted to them in Germany at that time only by M. Schultze and R. Leuckart, for other animal groups had fared no better among the then small number of scientifically working zoölogists, but Schmidt had won his earliest scientific fame with his little book on the fresh-water _Rhabdocoelas_ (1848), and had by means of it entered the circle of recognized investigators. He gave in this book the first connected presentation of the whole organization of a group of animals, the diversity and great abundance of which in fresh water were hardly suspected, and the anatomy of which consisted of few and imperfectly understood isolated data; described new systems of organs in them, and based an improved classification on their remarkably complicated and variously graded structure, with new families, genera, and species. The little book was therefore received with much interest. A journey to the Faroe Islands in 1848, and his first excursion to Lesina in 1852, followed in 1856 by a journey from Cracow to Nice and Naples, enabled him to increase the number of new species, and permitted an insight into the great diversity of forms, without, however, giving him time for accurate anatomical investigations, for the nature of the objects promised a considerable advance in this direction only at the cost of tenacious patience and untiring industry. His subsequent labors on the _Rhabdocoelas_ of the vicinity of Cracow, the _Dendrocoelas_ of the vicinity of Grätz, and his researches on the _Turbellaria_ of Corfu and Cephalonia, which (in 1861) closed this period of his career as worthily as it had begun, proved that Schmidt possessed both these requirements. These labors, if he had accomplished no more, would have been sufficient to give him an honorable position in science for all time.

"The second period begins in Grätz. Some contributions to the knowledge of the prehistoric vertebrate fauna of Steiermarck resulted from Schmidt's keen observations of Nature during an excursion in the Alps. But the Adriatic, so near, enticed him into new paths, and offered an inexhaustible field for work in the sponges. Aside from his contributions to the theory of the _Bathybius_ and to the systematics of the _Gephyrea_, the sea sponges constituted the object of his studies during the whole period of his residence in Grätz, and were the occasion of yearly journeys to the Adriatic coasts. The results reached by Schmidt in this field placed him in the foremost rank of contemporary investigators, while his occupation with the sponges marked the completion of a revolution in his view of Nature by converting him to Darwinism. After his work the characteristic fluid form of the sponges became a classic subject in the study of the transmutation theory.

"At the time of the appearance of Schmidt's first work on the sponges of the Adriatic (in 1862), just enough of their anatomy and physiology had been made known through individual labors, especially those of Lieberkühn, to prove their animal nature; and then, also, the sponges first found a place in the fifth edition of Schmidt's Handbook of Comparative Anatomy. But any one who undertook either in the Adriatic or the Mediterranean to make his way through the immense wealth of the forms would have found himself without help of any kind. It was therefore Schmidt's purpose to lay the basis, through exact description and definition of the forms, for continued investigation through which the study might be further advanced. He carried out this purpose, recognizing in the skeleton parts what survived amid the changes, clearly defining the species and genera, nineteen of which were new, and brilliantly demonstrating his talent in systematization. While in the first supplement, in 1864, which brought up the histology of the sponges, he still acknowledged himself an adherent of the old school, he expressed the hope in the second supplement that science might some time come upon the track of the genealogical relations of species; and, in the memorable rector's address of November 15, 1865, he openly signalized his passage to the new theory, and proclaimed it, with all the youthful enthusiasm and carelessness as to consequences characteristic of his nature, as the gospel of the research of the future.

"The idea of utilizing the great reproductiveness of the sponges for artificial cultivation was suggested to Schmidt during his studies of the Dalmatian fauna, and his experiments in this direction made his name well known in the Austrian coast land and far beyond. After the publication of an article on the subject in the _Wiener Zeitung_ he was requested, by the Imperial-Royal Ministry of Trade and National Economy, to make a special presentation of his views respecting the possibility and methods of cultivating sponges artificially in Dalmatia. He first asked for means for experimenting, as furnishing the prime and most essential method of determining where and how a sponge culture could be instituted with the best prospect of success. The request was not granted, but Schmidt was requested to furnish data respecting the provisions and measures within reach which might be employed with advantage till further information could be obtained concerning the adaptability of sponges to propagation from such local experiments as might be carried on through the industrial and commercial chambers of Dalmatia. The Notes on Sponges in the Adriatic Sea and an article of similar import in the _Triester Zeitung_ of March 12, 1862, were the answer to this request, and they were followed by Schmidt's having placed at his disposal, by the exchanges of Trieste, in the next season, money and the control of the war steamer Hentzis for use in scientific and practical investigations on the Dalmatian coast. With the assistance of his brother, Eugen, he carried his experiments to a successful issue at Sebenico, Zlarin Valle Socolizza on Lesina, Curzola, Lagosta, Meleda, and Ragusa, but especially in the more favored stations of Zlarin and Lesina, and demonstrated the possibility of artificial propagation. In order to test the practical value of the experiments, propagating stations were established on the island of Lesina and visited by Schmidt every spring. The results of the experiments were presented in a report to the Imperial-Royal Ministry of Commerce and National Economy, in which the possibility of artificial propagation was emphatically affirmed."

Unfortunately, the Dalmatines have not been quick enough to take advantage of the opportunity thus offered to them to establish a new industry on their not very busy coast. Bucchich continued Schmidt's experiments till 1872, but no capitalists have been found to establish the cultivation of sponges on an extensive and permanent scale.

Another enterprise, however--the Zoölogical Station at Trieste, to which Schmidt for a time devoted all his energy--has had a more fortunate realization. The plan of it was developed by Carl Vogt, but it would never have been erected if Schmidt's practical sense had not adapted the plan to the actual needs of the case and the financial conditions imposed by the state, and if he had not given the weight of his personality to the accomplishment of it.

The erection of a German Empire at the conclusion of the Franco-Prussian War was an occasion of proud and exultant joy to Schmidt; and when, in the spring of 1872, he was elected, at the instance of his friend Haeckel, a professor in the newly instituted university at Strasburg, he deemed it a patriotic duty to accept.

With his removal to Strasburg, what both Erich Schmidt and Professor von Graff call the third period of Schmidt's scientific career began. It was a period of undisturbed ease in his home life, and was devoted chiefly to the continuation of the studies of the sponges, with a few special researches, the results of which appeared in books, on the theory of descent, fossil animals, on Hartman's theories, and on social democracy. His systematic and anatomical labors on the sponges--the provisional conclusions of which, in 1870, constituted the _Grundzüge einer Spongienfauna des Atlantischen Gebietes_ (Outlines of a Sponge Fauna of the Atlantic Region)--were carried on, Professor von Graff says, from the point of view of the development theory. Besides several smaller contributions to the building up of the theory of descent, the most important of all his works of this time is his book on the Theory of Descent and Darwinism (Appletons' International Scientific Series)--"one of the best presentations of all the questions pertaining to that subject, and distinguished from other similar works both by the philosophical spirit with which the whole discussion is carried on, and by the even consideration it gives to all the various fundamental points of the principle of descent. The prominent features of Schmidt's presentation appear most especially in the final chapter, the subject of which is the Application of the Theory of Descent to Man, which he had also previously discussed in a public address. Shortly after this he reduced to absurdity, in a very forcible attack on Hartman's Philosophy of the Unconscious, the idea of the Social Democrats that they could use Darwinism to the advantage of their Utopia, and treated the subject of the Mammalia in their Relation to Primeval Times (Appletons' International Scientific Series) most vigorously from the point of view of the development theory." He also found time for special researches on the Structure and Development of Loxosema, the Eyes of Arthropods, and, still keeping up his studies of the sponges, closed his more than twenty years' labors on this group with his Sponges of the Gulf of Mexico, and his last scientific work--Derivation of New Species through the Decay and Atrophy of Older Characteristics. The preface to the former work, Professor von Graff says, shows plainly how Schmidt, in contrast to so many fellow-laborers in the field of the theory of descent, was always circumspect in a high degree, and never suffered himself to be carried so far in his zeal as to leave the ground of facts. Although a champion of monophyletic derivation, he did not overlook the facts that might be brought to bear in favor of a polyphiletic origin.

During the later years of his life Schmidt visited Heligoland, and enjoyed the sea air, which seemed to have become necessary to him, during two winters at Dohrn's Institute at Naples, in southern France, and at Grado, and attended the meetings of naturalists at Leipsic, Wiesbaden, Salzburg, Baden-Baden, Munich, Cassel, and Freiburg, where he was a welcome guest and a prominent speaker. In September, 1885, as president of the Zoölogical Section he entertained his fellow-specialists at his house. A slight stroke of apoplexy, which he suffered in the summer of 1882, passed away without seeming to leave any trace. He spent the Easter season of 1885 with his son's family in Vienna and with Graff in Grätz. He intended to speak on Easter of 1886 in Weimar and to visit Jena, "whither he expected to return in his sixty-fifth year so as to attach a good end to a good beginning." But on the morning of January 9, 1886, after he had spent the previous evening in pleasant social intercourse, there came another stroke. He never recovered consciousness, but died on January 16th.

Professor von Graff describes Schmidt's method of teaching as one encouraging the students to pursue their own ways of thinking. He did not expect formal theses from them, but, having indicated the theme, left them to work it out according to their own logical processes, and as often let them choose their own subjects. Having found a pupil's bent, he sought to turn him into a corresponding course, "and never tried to make a poor naturalist out of one who might become a good doctor or teacher." In his lectures he was earnest and enthusiastic, not as good a speaker as writer, and sometimes betraying his trouble to find the right word; "but he knew how to win the love of his pupils for his subject, and, while trying to make the comprehension of the matter not too difficult, to keep interest alive by occasional glances at the theoretical significance of the facts. It was very far from his purpose to make pastime for his hearers, and, when he was polemical, every one had to be made sensible of the purely technical bearing."

Professor Schmidt's literary work covered a field of extraordinary breadth. Besides numerous works and text-books in systematic and anatomical zoölogy and life histories, he published popular lectures and essays in many different periodicals, recensions, reviews of books, translations, and even political articles. It would be impossible to give a complete bibliography of his works, because he left no notes respecting them. A list of his publications in zoölogy, by Professor von Graff, includes ninety-nine titles.

SCIENTIFIC METHOD AND THE BIBLE.

_Editor Popular Science Monthly_:

SIR: I have read with great interest an article in the July number of your Monthly entitled Scientific Method and its Application to the Bible. So far as I am able to understand the writer's views, I must certainly decline to accept some of his conclusions. The vital teaching of his paper appears to me to be this: it is proper to apply scientific methods to the study of the Bible so far as to inquire into its structure, the date of its composition, its composite authorship and the sources from which it was compiled, and the names of its authors; but certain truths are distinctly taught in it of a supernatural character which must be accepted because they are a revelation of God's will, and not because they are found to be true by intellectual apprehension and logical reasoning. Indeed, to think of understanding them by intellectual processes is "unscientific beyond hope of pardon."

It is conceded that "the stifling of thought and of investigation into what might lead men away from the truth and the faith once delivered to the saints" was instrumental in causing the barrenness in scientific work for twelve hundred years of the middle ages, between Hipparchus and Copernicus, and that "the same causes are more or less at work at all times to hinder the growth of science and the extension of scientific method." He still, however, insists that there is limitation to human inquiry and ecclesiastical bounds beyond which thought must not go. There are still revelations of truths which the intellect can not perceive, and which can only be understood by "an exercise of faith." It is no longer the Mosaic line which scientists are forbidden to cross, but the "spiritual verities" must not be questioned. There are some revelations which, in the language of Huxley, "they are to hold for the certainest of truths, to be doubted only at the peril of their salvation."

Was it not Martin Luther who called Copernicus a "fool" for trying "to reverse the entire science of astronomy" in the face of revealed truths? "To accept the truth as revealed by God and to acquiesce in it is the part of a good mind," said Melanchthon in condemning Copernicus. "Who will venture to place the authority of Copernicus above that of the Holy Spirit?" said Calvin. Verily, his unpardonable sin was "investigating the truths which are distinctly taught in the Bible," which required an "exercise of faith" and were not to be "apprehended intellectually."

The question seems a reasonable one to ask, To what authority shall we look for knowledge and interpretation of these spiritual truths which are not accessible by scientific study? How shall we know that they are truths at all? I am aware that here the testimony of Christian conscientiousness is sometimes held to be the court of last resort, which I interpret to mean that if one intuitively reaches the conclusion that something is true it is true, the most positive evidence to the contrary notwithstanding. Certainly, no other fact is better established in all human history than the truth of witchcraft, if we admit the potency of this authority. If we reject this, must we not then fall back upon ecclesiastical infallibility as the final interpreter of truth? And this the essayist, in his paper, declines to argue.

Now, can there be any such thing as scientific investigation within such prescribed limitations? Or scientific study of the Bible itself which excludes from its province the so-called spiritual revelations which it contains? One might naturally think that the primary purpose of all the critical study of the books, authors, and structure of the Bible was to learn just what these distinct truths it teaches are. But what bearing can this study have upon the question, being but an intellectual process with which the essential truths are disconnected, which only come by revelation?

Higher criticism can not hold permanently such an untenable position. It must either go backward to an infallible book, or an infallible interpretation of it by authority, or it must go forward to the consideration of the Bible as a collection of books of ancient literature, to be examined without restrictions. The truths which it contains are to be ascertained by "apprehending intellectually" and "reasoning logically," in the same manner as with other books written by religious leaders in ancient times. Any halting between these two positions is only for temporary rest. No permanent foothold can ever be gained on such a foundation of quicksand. An impassable dead line in biblical study is indicative of the theological and not the scientific method.

A CORRECTION.

_Editor Popular Science Monthly_:

SIR: A correspondent, Mr. C. Wood Davis, of Peotone, Kansas, appears to think it his duty to prove that we can not produce wheat enough in this country to meet our own future demands, and apparently regards it as a personal matter when any one contests this position. He also thinks he has found a small error in long division in the last article which you printed from me on this question which I can not find, but which if found and corrected would have no influence on the general argument.

He also rebukes me in a most earnest manner for the alleged misuse of the chemical term "phosphate of potash," which crept into my article in connection with the right use of the term "phosphate of lime," when I referred to the mineral phosphates of Kentucky, Tennessee, and Florida. Technically he is apparently right. There is no permanent form or no natural mineral form of phosphate of potash which can be removed from place to place. Yet my article was revised by an experienced geologist, thoroughly familiar with the chemistry of the soil, before I sent it to you, and he failed to correct this technical error. My own knowledge of chemistry is very limited.

It might be inferred, as my irascible correspondent points out, from the manner in which I have called attention to the deposits of mineral phosphates in Kentucky and Tennessee, that I thought these deposits would yield phosphates of lime and phosphates of potash each in a separate movable form, which could not be a fact. Yet my critic will doubtless admit that the soils of many parts of this country are stocked with potash sufficient for a very long period.

Many years ago, when I began the study of the cotton plant and its growth, under the leadership of the late Prof. William B. Rogers, I made reference to the existence of the vast supplies of phosphate of lime and potash, which are necessary to the growth of the cotton plant, in the Southern soils. I derived my conception of their origin in the lowlands and plateaus in marine formations from Professor Rogers, and also from the works of Professor Shaler. One may also impute the large amount of potash that is found in the valleys and mountain lands to the disintegration of the gneiss and other rocks of the Appalachian chain, which have never been washed out by glacial action or by glacial streams. If any one has been misled by this slight misuse of chemical terms it may be well to state that phosphate of potash does not exist, and I am told that it can not exist, in a separate removable form.

We have not as yet discovered any large deposit or mine like that of Stassfurt, in Prussia, yielding potash in a commercial form in which it can be widely distributed. We import annually thousands of tons of potash from Stassfurt. This deposit was discovered, as I am informed, by accident, and it may be hoped that a similar accident may occur in this country. These mines were originally opened for the production of salt. In boring for salt the product of a stratum above or below the salt, I know not which, was brought up, which was thrown aside as worthless until an inquisitive visiting chemist examined it and thus discovered this great source of potash. We possess enormous beds of salt, of soda, and of alkalies, scattered throughout the area of this country, in connection with which it may be hoped that we may hereafter discover a deposit of mineral potash, or of the mineral from which potash may be derived cheaply and in large quantities.

These two exceptions which have been taken to my article have no real connection with the substance of the argument, which stands independently either of the undiscoverable error in long division or of the technical fault in the use of the term "phosphate of potash." Yours very truly,

EDWARD ATKINSON.

Editor's Table.

_AN OLD-FASHIONED MORAL._

Voltaire's Candide is not a book that can be recommended for general reading; yet it contains perhaps as good a moral as could easily be found in a wide range of books aiming more distinctly at edification. The hero, after many vicissitudes and copious experience of the deceitfulness of riches and the miseries of an ill-regulated life, made the blessed discovery that peace and health and independence were to be obtained by the industrious cultivation of a small piece of ground. He had a friend called Martin who associated himself with him in his agricultural labors, but who had rather a fine talent for discussing abstract questions. Candide would listen to him for a while, but never allowed him to get very far without breaking in with the observation, "Mais surtout il faut cultiver notre jardin" ("But above everything else we must cultivate our garden"). Here was safety, here was balm for painful recollections, here was about the best that the world had it in its power to give; and Candide, chastised by misfortune, wanted to stick to that.

This is an age of copious and unending discussion of social and political problems. Discussion is well in its way; but perhaps the problems would not be so acute if there was less discussion and more cultivating of gardens. It may indeed be said, with no small degree of plausibility, that the greed to be rich, the unwillingness, so to speak, to cultivate a garden which only promises a moderate reward, is at the bottom of a large part of our troubles. Wisdom cries aloud and tells the world that happiness is not to be found in riches; but the cry is little heeded. The whole lesson of higher education is that happiness springs from within and not from without; but thousands take what they can of the higher education while declining the lesson. Science unlocks a world of beauty and wonder, and offers to the mind a constant succession of interesting subjects of contemplation; but thousands again ask nothing of science except to show them the way to wealth. Precisely similar in a multitude of cases is the demand made of art and literature. It is well-nigh a century since Wordsworth lamented the decay of "plain living and high thinking." Have the succeeding years brought any improvement in this respect? It is much to be feared they have not. Wealth is, if possible, more than ever the ideal of society, and plain living is terribly at a discount.

We believe, however, that in the deliberate choice of plain living by an influential portion of society there lies a greater potency of social reform than in all the schemes of socialistic reconstruction. The most hurtful thing in the world to-day is the false glamour of wealth. It is against this evil influence that we want an insurrection, not against capital as such. Weaken the fascination of wealth, and, in the same degree that you do so, you increase the moral responsibility of those who are its possessors. The luxury of the present age has run to a dangerous extreme. Advice in such a matter may seem idle, but the discovery that Candide made is one that the world at large must make some day. True happiness is the natural accompaniment of honest industry and moderate living. Such conditions make high thinking possible, and give a savor to all enjoyments. There have been times when men, to save their souls, would go forth into the wilderness or the desert. Such sacrifices are not needed in the present day; there is a very respectable measure of salvation to be won in cultivating a garden.

_THE TROUBLES OF ORTHODOXY._

The thought of the age has now reached a point of development at which it has become almost impossible for any man of trained intellect to say that he receives on authority pure and simple any statement which admits or should admit of direct verification--for example, any statement dealing with matters of a historical or scientific character. This, if we mistake not, is the true secret of the troubles over doctrinal questions which have lately broken out in more than one division of the Christian Church. It is not so much that there has been a revolt against doctrines as such, as that a need is felt by thinking and cultivated men to seek for higher grounds of belief than those hitherto deemed sufficient. This has led to a certain generalization of belief, if we may so call it, which to less cultivated minds looks almost like an abandonment of the most essential doctrines of the Christian faith. Such a view of the matter, however, we hold to be entirely erroneous. The men we are thinking of--and Dr. Briggs and Bishop Potter may be taken as conspicuous examples--have the interests of religion and of their fellow-men at heart. They do not wish to force upon others a mode of looking at religious questions for which they are not prepared; but, for their own part, they find it necessary to restate the articles of their religious faith in terms which do not absolutely conflict with the principles of reason. This rectification of terms is imposed in part by the conditions of thought in the modern world, but to an equal extent at least by what may be called an inward expansion of the doctrines themselves. Who that holds any truth, scientific or other, does not feel impelled to seek for it continually a wider interpretation and application? Not otherwise is it, we hold, with religious doctrines; they have their own law of growth and development, and he who would arrest the process condemns them to atrophy and decay.

It is charged against both the scholars we have mentioned that they speak of the Bible as literature, and say that in determining its meaning we must keep in view the same class of considerations which would guide us in dealing with other literary monuments. There is nothing in this which need alarm any thoughtful person. It would be doing less than justice to the Bible to deny that many parts of it are literature of a very high order; and it would be doing less than justice to our own intellects to deny that the conception of the Bible as literature is a great help to its correct interpretation. Religion, in the view of such men as we have mentioned, does not depend upon the meaning given to a text or the acceptance or rejection of any specific statement of fact. There is nothing specially "religious" in believing that the Epistle to the Hebrews was written by St. Paul, or that the adventures of Jonah were precisely as described in the book that bears his name. Grant that the organ of religious apprehension is faith, yet each age must settle for itself the question as to what is the proper scope of faith and what of reason. In the present day reason can deal with many things which at one time were thought to be entirely within the domain of faith, and it would be rash to say that the frontier has even yet received its final rectification. If we rightly understand the position of Dr. Briggs and Bishop Potter, they hold that religion is essentially an attitude of mind and heart, a seeing of the invisible, an instinctive recognition of a supreme moral authority, a sense that every human being is called to nothing less than holiness of life. They reverence the Scriptures because in them, as in no other body of writings in the world, the realities of religion are both expressed and implied. They do not demand of the Bible perfect agreement with either scientific or historic truth; they are content if they find in it the spiritual basis of human life, a scheme of thought that links the individual human being with an infinite origin and an infinite destiny. From their standpoint the value of the Bible for the highest moral purposes would in no way be increased if every word in it which touches on scientific or historical questions had the seal of all the academies in the Old World and the New.

It is not a difficult thing, nor does it require much wisdom, to harry a man whose independent thinking and moral earnestness have forced him to take a different attitude toward some great question from that which is adopted by the multitude. It is easy to present his views in an invidious light, but a more useful task would be to show that all that is essential and precious in religious belief can exist as well in a philosophical as in a popular form. With such a thesis it may not be quite so easy to "score," but it is a pity when the standards of the reporters' room invade the desk of the literary or theological editor. It is upon such men as we have mentioned, men of competent scholarship and earnest spirit, that the task is laid of purifying and liberating the religious consciousness of the age; and we do not hesitate to say that when, from the vantage height of modern knowledge, they affirm with deep conviction the indestructibleness of the religious sentiment and the everlasting reality of its object, they render a service which, from a religious point of view, can not be overestimated.

Scientific Literature.

SPECIAL BOOKS.

In a stout volume[G] of nearly a thousand pages Mr. _Jackson_, the leader of the Jackson-Harmsworth Polar Expedition of 1894-'97, puts into permanent form the record of three years' observations made in Franz-Josef Land, a region beyond the eightieth parallel of latitude, which was accidentally made known to the world twenty years before by the drift of the Tegethoff, the ill-fated vessel of the Austrian expedition of Payer and Weyprecht. As such it is a substantial contribution to arctic literature, and from it much important detail will be obtained by those seeking further adventure in the quest for the pole, and a mass of material, geographic and otherwise, pertaining to the region which forms the subject of the work before us. The meteorological data, covering as they do a longer continuous period of observation in the extreme North than has heretofore been possible, and fittingly supplementing those recorded by Nansen for an almost equal period, will be specially prized by the scientist, even if the facts of the air are not considered to be the main object of arctic research. It is interesting to note, from the observations on temperature, that the lowest record was only -46° F., the extreme rigor, consequently, being only that of Dakota or Manitoba, and marking nearly fifty degrees above what has been observed a thousand miles farther to the south at Verkhoyansk, in Siberia. Nothing approaching the extreme cold (-72°) noted by Kane and by the Nares British Expedition of 1875-'76 has thus been recorded by Nansen, Peary, or Jackson.

[Footnote G: A Thousand Days in the Arctic. By Frederick G.
Jackson, Knight, First Class, of the Royal Order of St. Olaf,
etc. New York and London: Harper & Brothers, 1899.]

Mr. Jackson's claims to discovery lie mainly in the field of geography; for, while the observations on zoölogy, botany, and geology are by no means meager or lacking in originality, the results obtained have been largely anticipated by other investigators--notably Payer, Leigh Smith, and Nansen. In the domain of geography, however, there is a distinct contribution, and the author has missed no opportunity to add to the catalogue of geographical names by "rounding up," as it were, the numerous points which appeared new to him or were thought worthy of designation. This diligence in applying names, at times to points or places which are wholly insignificant and which could be followed with equal advantage or disadvantage on most of the known coast lines of either Europe or North America, can hardly be said to detract from the value of the discoveries actually made, although their publication, from advance letters received by Mr. Harmsworth's representative in London, has caused hostile comment and bitter controversy, even on the part of British geographers and scientists. Much of Mr. Jackson's work, it was contended, was directed to demolishing the work of Lieutenant Payer in the same region, and toward substituting names for those given, whether with a correct placing or not, by the Austrian commander--in itself a legitimate undertaking, but heralded out, it was claimed, to mask Mr. Jackson's own failure to accomplish the real task of his expedition--the finding of the north pole. Mr. Jackson has certainly very largely remodeled Payer's map of the archipelago, but the new map in no way discredits the attainments of his predecessor, even though showing up many and even glaring inaccuracies in the cartographical details published by him, for allowance must be made for the limitations under which the Austrian commander made his work. The vital points which have to be eliminated from the geography of Payer are: That Franz-Josef Land is a congeries of no very large islands, without continental extent northward, and that much that has been represented to be land is, in fact, water or ice, the appearance of land in the frozen North being frequently suggested by the vast gray and ill-defined ice masses which loom up in fog and mist, both as flat sheets and mountain buttresses.

It was the failure to find a northward continental extension to Franz-Josef Land, such as had been thought to possibly exist by Payer, which led Jackson to abandon all effort to advance upon the pole--a condition which appears, at this time, the more surprising seeing that two expeditions, those of Walter Wellmann and the Duke of Abruzzi, with all of Mr. Jackson's facts before them, have elected this same route as the one most calculated to bring about a successful issue, and certainly much can be said in favor of it. While the Franz-Josef Land route may not commend itself as the one best to be followed--and surely the open highway which from time to time appears north of Spitzbergen offers marked advantages for one without a land following--it still has its advantages in the point of high northern departure, and arctic authorities will fail to be impressed by the negative conditions which were obtained from it by the Harmsworth Expedition. Manifestly, Mr. Jackson had prepared himself for one form of journey only--that of following the land, a singularly blind limitation, considered in the light of the little that was positively known of such land extension as the expedition had counted upon, and one that is disagreeably emphasized by the lavish expenditure of money that had been put to the expedition, and the personal confidence that had in some quarters been expressed in its success. Without wishing in any way to disparage or minimize the importance of Mr. Jackson's work, or to underestimate the hardships of any form of arctic exploration, one can not but feel surprised and in a measure disappointed that an expedition designed primarily for an advance upon the pole, which passed the better part of three years beyond the eightieth parallel of latitude, and whose members during this time did not know a single day of sickness--an almost unprecedented performance in arctic methods--should have found itself in a condition unable even to make an effort upon the "open." The recollection of Parry's performance in the frozen sea north of Spitzbergen in 1827, of Markham's advance in 1876, and of Peary's "treck" across the north of Greenland in 1892, emphasizes only more deeply this feeling of disappointment.

Mr. Jackson has made a very careful study of Franz-Josef Land, and has brought that region into a condition of knowledge similar to that which the different Peary expeditions have brought to the north of Greenland. His narrative is simple and direct, virtually a transcript of notebook and diary, without embellishment of any kind, and with a statement of facts and conditions such as they appeared almost at the instant of time of their occurrence. While indisputably impressing a truthfulness and reality, it can not be said that this method adds to the readableness of the book, which is overburdened with repetitions, frequently in identical words and sentences, to a useless and, one is tempted to say, most distressing extent. It is to be regretted that an explorer of the marked energy, routine, and persistence which are Mr. Jackson's qualities should have faltered in what by some travelers has been considered the most arduous part of their task--the proper preparation of a report--for surely it can not be conceived that a good purpose was subserved, either in a popular or scientific aspect, in the publication of wholly unimportant matter, over and over repeated, merely because it formed part of an official diary. The work is abundantly illustrated throughout with half-tone reproductions from photographs, taken by Jackson and his companions, that give a vivid reality to the journey which no amount of word-painting, even when so skillfully handled as by the present author, could prove a substitute for. Scientists will be gratified to know that supplemental reports, prepared by specialists in different departments, may be expected before long to fill out the full scientific aspects of the exploration.

On one point in connection with Mr. Jackson's discoveries the geographer, not less than the lay public, has the right to break straws with the author--that is, the method of naming the new points of land, water, and ice. Zoölogists and botanists have long been guilty of an absurd levity in the discharge of their obligations as namers of new species, and have burdened the vocabulary of animal and vegetable names with thousands of _personalia_ which in no way called for perpetuation, and many of which were suggested only by way of ridicule or jest. So long, however, as these were dressed in Latin or Greek form and remained merely the possession of the scientific world there was little to complain of, and even the objections of the extreme sentimentalists might have been met by an appeal to the difficulty of obtaining or coining judicious or otherwise appropriate names. The case is different with the naming of places on the earth's surface, which at this day can be done with direct reference to euphony, to a certain appropriateness of dedication or appeal, and the intelligence of the student. A map of the world is intended for everybody, and not for a class of specialists, and its symbols are devised for readers of all classes. Maps of America have particularly suffered from irrelevant and commonplace designations, and only during recent years has the money value of names suggested radical changes, as in the case of many of the seaside resorts of the middle Atlantic coast. But, with all our indifferences and extravagances of even a half century ago--the period of Hog Hollows and Yuba Dams--a no cruder infraction of the logic of nomenclature can be found than in the coining of such names as "Cape Mary Harmsworth," "Cape Cecil Harmsworth," "Alfred Harmsworth Island," "Harold Harmsworth Straits," "Cape William Bruce," "Bruce Island," "Mabel [Bruce] Islands," "Mabel Bruce Fjord," "Albert Armitage Island," "Cape Alice Armitage," "Ceceil Rhodes Straits," "H. M. S. Worcester Glacier," etc. These have not even the advantage of an old-time arctic "ring" about them. Courting popularity by the bestowal of all manner of personal names, irrespective of direct relation to the expedition or to geographical exploration, is hardly commendable, and is only less objectionable than the plan suggested a few years ago by an American would-be arctic explorer to "sell" the names of places to be discovered to the highest bidder--i. e., according to a graded schedule of contributions to the expedition funds.

GENERAL NOTICES.

_On the South African Frontier_[H] is a narrative of the experiences and observations of the author, Mr. _William Harvey Brown_, partly as naturalist of the United States Government Eclipse-observing Expedition of 1889 to the west coast of Africa, and partly as a resident in various occupations for seven years in Rhodesia. The principal object in composing it was to give American readers a clearer idea of English operations in conquest and colonization on the South African frontier than it is possible to glean from current fragmentary accounts. The author served his apprenticeship at natural history collecting under Prof. L. L. Dyche, of the University of Kansas, and Mr. W. T. Hornady, of the New York Zoölogical Gardens, and was recommended by Mr. Hornady to the Government for the Eclipse Expedition. He sailed first to Freetown, then to St. Paul de Loanda, where he spent a few weeks collecting, establishing his headquarters at Bishop Taylor's American Methodist Self-supporting Mission. Thence, after a short attack of African fever, he proceeded to Cape Town, where he was attacked by the other sort of African fever--"an irresistible longing to penetrate the Dark Continent for purposes of exploration and of observing both man and Nature." He made the journey overland to Mafeting and to the Mashona country, in the region of which he spent seven years as "game-hunter, gold-seeker, landowner, citizen, and soldier," observing and participating in the settlement and early development of the new state of Rhodesia. The larger part of the book is devoted to his adventures and observations, "travel, collecting, hunting, prospecting, farming, scouting, fighting," and seeing pioneer life. Two chapters are devoted to ethnology. The race problems which arise during the stage of transition from barbarism, the agricultural and mineral resources of Rhodesia, and its prospects and possibilities, are discussed.

A very handsome book, in what to many are the most graceful and interesting forms of vegetable life, is Mrs. _Parsons's How to Know the Ferns_.[I] The name of the author is new, but the author herself is a familiar friend to all lovers of American field and wild-wood life, for she is none other than Mrs. William Starr Dana, who had already given us How to Know the Wild Flowers and According to Season. In this book she does as she did with regard to the wild flowers--takes her readers to the haunts of the ferns and into their company, introduces us to them, and before she is done makes us well acquainted with them. "It seems strange," she says, "that the abundance of ferns everywhere has not aroused more curiosity as to their names, haunts, and habits." Possibly it is because they are so common that we are not at pains to seek greater intimacy with them. Then, they depend on the beauty of graceful proportion, which is less obvious to careless eyes than that of color. First, Mrs. Parsons discourses of Ferns as a Hobby, and the pleasure we may derive from them; then she tells when and where to find them, defines the terms used in speaking of them, explains their fertilization, development, and fructification, gives a list of notable fern families and descriptions of the American ferns classified into eight groups according to the arrangement of their spores, and completes the work with indexes of Latin and of English names and of technical terms.

_The Microscopy of Drinking Water_[J] is intended by Mr. _Whipple_ primarily to serve as a guide to the water analyst and the water-works engineer by describing the methods of microscopic examination, assisting in the identification of the common microscopic organisms found in drinking water, and interpreting the results in the light of environmental studies. A second purpose is to stimulate a greater interest in the study of microscopic aquatic life and general limnology (the lessons of lakes and ponds) from the practical and economic point of view. The work is elementary in character. Principles are stated and illustrated, but the last ten years' accumulations of data are not otherwise attacked. The illustrations have been largely drawn from Massachusetts cases, from which there may be differences elsewhere, but not very great as to microscopic organisms. The latter half of the book is devoted to descriptions of a limited number of organisms, chosen for the most part from those commonest to the water supplies of New England, and those that have best illustrated the more important groups of microscopic animals and plants. Most of the illustrations have been drawn from living specimens or photomicrographs of such, but some are reproduced from other sources.

It is evidence of appreciation of Dr. _Wetterstrand's Hypnotism and its Application to Medicine_[K] that, written in Swedish, it has been translated into German and Russian, and now into English. The German work, from which the present translation is made, was enlarged from the original, and embodied the results of additional experience. The author disavows the intention of writing a manual or text-book, and modestly assumes only to have given "unpretentious notes by a physician who, under the pressure of a fatiguing and engrossing practice, has not been able to develop his rich material into a more complete form." The book is characterized by the translator as more practical than theoretical, and as offering the results of conscientious and able observation. Hypnosis is defined by Dr. Wetterstrand as embracing a number of various conditions of the nervous system, which can be produced in different ways. "We recognize phases of the greatest variety, from a slight heaviness in the limbs, the most superficial somnolence enabling the hypnotized subject to hear and perceive the least noise, to the deepest sleep, from which the greatest disturbance can not awake him, and wherein every sensation disappears and permits the most serious surgical operation without pain." The author believes that the majority of people can be brought into any of these conditions, but the methods and degrees of difficulty of the process are various. "Liébeault distinguishes five degrees in hypnotic sleep, Bernheim nine; but Wetterstrand thinks they may all be grouped under three. Suggestive therapeutics is regarded as by no means a panacea, but it succeeds in cases where other methods have failed," and, as Bernheim says, "often it produces miracles." After an outline of the general principles of the subject the author passes on to describe some diseases and morbid conditions in which he has employed hypnotism with the greatest results, culling from his notes, as impartially as possible, both successful attempts and failures. The cases include insomnia, the list of nervous diseases, drug diseases, consumption, rheumatic, heart, and other organic diseases, and functional affections; with the use of suggestive therapeutics in operations, obstetrics, and on some other occasions. Dr. Petersen's medical letters on hypno-suggestion, etc., added to Dr. Wetterstrand's work, are intended to give a succinct idea of the present status of practical psychic therapeutics, as based on the observation of clinical facts. They relate to suggestive treatment in reform work, post-hypnotic responsibility, and music in hospitals.
