Chapter IX: Part I: By Philip P. Carpenter, B.a., Ph.d (2)

Alæ supra fulvæ, marginem versus brunneæ, fasciis maculisque
ordinariis omnibus albis nigro marginatis instructæ. Subtus alæ
anteriores fulvæ, apice et margine grisescentes, fasciis et
maculis ut supra. Alæ posteriores grisescentes, macalis albis
et nigro marginatis et confluentibus cum colore universali
irregulariter variegatæ.

The most positive and striking points of difference would be
thus:

1. _N. Dumeti._ Fore wings alone show a fulvous coloration on
the upperside. Bands and spots perfectly white.

2. _N. Mejicanus._ All wings are occupied with it, till beyond
the second band, where the brownish coloration of the margin
begins. Bands and spots perfectly white.

3. _N. Virgulti._ Extension of the fulvous as in the preceding,
but all the space more or less occupied by black. Middle band
nearly altogether fulvous, other bands and spots white.

As much as we know, the type of this genus _N. Lucina_ L, was
the only species known heretofore, and it is another proof of
the various repetition of types on occidental coasts, that we
have to add three Pacific representatives of a genus first
discerned in a single European species.

The group of the _Erycinides_ belongs essentially to tropical
America. The beforementioned _Nemeobius Lucina_ is the only
European representative of this numerous and polymorphous
group. Besides this, there exist some few Asiatic members of
this family, very aberrant in their type, scarcely known and
insufficiently examined, so that possibly they may belong
somewhere else. In America the tropical genera _Nymphidia_ and
_Lemonias_, extend beyond the Cancer on the Atlantic side; but
on the Pacific side reappears the European genus _Nemeobius_,
extending into the Tropics, and seems to find here its very
centre.

Description of New Species of Land Shells.

BY W. NEWCOMB, M.D.

_Helix Blakeana_, Newc.

Hel. testa unicolor flavido-alba, rotundato, semi-globosa,
nitida, translucida; umbilico amplo, profundo et parum obtecto;
apice obtuso; anfractibus sex, convexis, tribus superioribus
sub-planis, reliquiis rapide accrescentibus, ultimo inflato;
sutura bene impressa; aperturâ rotundato-lunare; peristomate
tenue, ex panso-reflexo cum columellâ sub-late dilatatâ, non
adnatâ.

Alt. ·7 pol., Diam maj. 1·1 pol., min. 1· pol.

Hab. Insula Niphon—Japan, (teste Blake).

Shell uniformly yellowish white, rounded, half globular,
shining, translucent; umbilicus large, deep and slightly
covered; apex obtuse; whorls six, convex, the three first
nearly on the same plane, the balance rapidly increasing, the
last swollen; suture well marked; aperture roundly lunar; lip
thin, flatly reflected, at the columella broadly dilated but
not adherent.

NOTE.—In general form and color, this species makes a nearer
approach to _H. candida_, Moricand, than to any species with
which I am acquainted. It varies in the less elevation, in
the form of the spire, and in some other respects. Professor
Blake had remarkable facilities for collecting in Japan, but
unfortunately the mice proved so destructive to his terrestrial
shells, as to leave him but few specimens as the result of his
labor.

_Helix declivis_, Newc.

Hel. testa perspectivo-umbilicata, lenticulare, oblique
striata, tenue, pallide-cornea; anfr. IV, planulatis, ultimo
declivi, in medio sub-carinato; sutura sub-canuliculata; peris.
fragile, simplici: apertura obliquo-sub-rotundata.

Alt. ·1 pol., Diam. maj. ·3 pol., min. ·2 pol.

Hab. Insula Niphon, (Japan).

Shell perspectively umbilicate, lenticular, obliquely striate,
thin, pale horn color; whorls four, planulate, the last
shelving down to the centre, which is obscurely keeled; suture
channelled; lip fragile, simple; aperture oblique, almost round.

REMARKS.—Bears some resemblance to _H. ruderata_, Stud.,
a species common in Europe, from which it may readily be
distinguished by comparison.

NOTE.—The Japanese species herein described, were collected by
Professor Blake, in the interior of the Island of Niphon, out
of the range permitted to foreign travel.

The Professor, who was employed by the Japanese Government as a
special geologist, had the privilege of penetrating districts
not before visited by any scientific or mercantile foreigner.
The following species of Helices were also among those
collected:

_Helix peliomphala_, Pfr., (Mon. Hel. viv. Vol. 4, Sp. 1764).
_H. quesita_, Deshayes, (Reeve’s Mon. fig. 1355).
_H. Perryi_, Jay, (Perry’s Exped. Vol. 2, page 294, Plate 5,
fig. 7, 8, 9).
_H. Simoda_, Jay, (do. fig. 1 to 6).

Some doubt may exist as to the _H. quesita_ being identical
with _H. Perryi_. But one specimen was preserved, and this
fully agrees with the description and figure of the first
named, but the locality for the species is given as the
“_Moluccas_.”

It also agrees (except in colour) with Dr. Jay’s description,
and also in the very poor figures illustrating the species of
_H. Perryi_. The only question in my mind is one regarding
locality.

_Helix Cronkhitei_, Newc.

Hel. testa aperta umbilicata, depressa, luteo-cornea sub-lente
regulariter costulato-striata; spira depressa-convexa; sutura
excavata; anfractibus quatuor, sub-cylindraceis; umbilica
ampla, sub-perspectiva; apertura rotundata; peristomate
simplici, acuto, marginibus conniventibus.

Alt. ·15 pol., Diam. maj. ·2 pol., min. ·15 pol.

Hab. Klamath Valley, Oregon, (Gabb).

Shell openly umbilicate, depressed, yellowish horn colour,
under the glass regularly rib striated; spire depressed, a
little convex; suture wide and deep; whorls four, rather
cylindrical; umbilicus large, indistinctly perspective;
aperture rounded; lip simple, acute, margins approximating.

REMARKS.—Mr. Bland may _possibly_ refer to this species as _H.
striatella_, Anthony, which was obtained by Dr. Cooper on the
Pacific side of the Rocky Mountains. (See addenda to “Remarks
on Classification, etc.,” 1863). This species is certainly
distinct from _striatella_, by its smaller size, rib-like
costa, and almost channelled suture.

A few specimens were obtained by Mr. Gabb, of the State
Geological Survey, in Klamath Valley, which were collected
jointly by himself and Dr. Cronkhite, U. S. Army.

_Helix Rowelli_, Newc.

Hel. testa aperta-umbilicata, orbiculato depressa, alba, opaca,
polita, minutissimo-oblique striata; anfractibus quatuor
vel quinque convexis, ultimo magno antice deflexo; spira
vix elevata, apice sub-mamillato; sutura modice impressa;
apertura fere circulari; labro tenui, reflexiusculo, marginibus
continuis ad juncturam; anfr. ultimo adnato.

Alt. ·4 pol., Diam. maj. ·6 pol., min. ·5 pol.

Hab. Arizona, (dicto Frick).

Shell with open umbilicus, orbicular, depressed, opaque white,
polished, very finely obliquely striate; whorls four and a
half, convex, the last large, anteriorly descending; spire but
little elevated, at the apex projecting like a nipple; suture
moderately marked; aperture truly circular; lip thin, slightly
reflected, margins continued, adhering to the last whirl.

REMARKS.—This is another of the Cyclostomoid species of
which _H. Carpenteri_, Newc., _H. Cærulano_, Muhl., and _H.
Angasiana_, Pfr. form striking examples. Our species approaches
nearer in lightness of substance and in its depressed form to
Muhlfeldt’s shell, than to either the others.

I take pleasure in dedicating this species to the Rev. M.
Rowell, of San Francisco.

_Succinea Japonica_, Newc.

S. testa ovato-conica, flavido-cornea, lævissima, striatula,
nitida, pellucida; anfractibus III, nucleo sane mamillato,
ultimo 4·5 longitudinis fere æquante; apertura elongato-ovali;
peristomate simplici; columellâ regulariter arcuata ad
juncturam labro superiorem acuto-angulata.

Long. ·55, Diam. ·35, Apert. long. ·4, lata. ·233 pol.

Hab. Japan, (Prof. Blake).

Shell ovately-conic, yellowish horn color, very smooth, finely
striate, shining, pellucid; whirls three, nucleus truly
mamillate, the last four-fifths of the entire length; aperture
elongately ovate; lip simple; columella regularly arched; at
the juncture of the lip above, acutely angular.

_Remarks on Helix Hillebrandi_, Newc.

At the time of publication of this species, but a single
recent specimen had been obtained, and that was freed from the
epidermis. The statement that the shell was _hirsute_, was
founded upon the cicatrices observed upon the surface, Mr.
Gabb, who has recently returned from a trip to Mariposa, was
successful in finding a few specimens, by which the diagnosis
may be enlarged, and conjecture resolved into certainty. The
whole surface is covered with an epidermis, of a yellowish
brown colour, thickly studded with slightly curved rigid
hairs about one-twentieth of an inch in length. The animal
is of a reddish brown color, with the tentacles of a smoky
hue; tentacular sheaths darker than the body, which is small,
slender, finely granulated and unusually long and tapering
behind.

The shell bears the same relations to _H. Dupetit Thouarsi_,
Deshayes, that _Helix infumata_, Gould, bear to _H. fidelis_,
Gray. In the description of _infumata_, an important omission
occurs, owing doubtless to the imperfect condition of the type
specimen. In good specimens, all of the last whirl, except a
circle round the umbilicus, is covered with _very short_ and
thickly studded soft hairs, feeling harsh when dry, but velvety
to the touch when moistened.

_Achatinella Alexandri_, Newc.

Ach. testa perforata, sinistrorsa, elongato sub-cylindracea,
nitida, rufo-brunnea, nigro-elongato-venulato-inosculante
picta; anfr. VI convexis, regulariter accrescentibus; apice
obtusiusculo; sutura modice impressa, non emarginata; apertura
parva, sub-ovata; labro acuto; columella alba breve, sub-recta,
truncata, infra in plicam tortam terminante.

Long. ·6 pol., Diam. ·25 pol., Aper. long. ·2 pol. ·1 lata.

Hab. Insula Sandwich, (Maui).

Shell perforated, left handed, elongately sub-cylindrical,
shining, reddish-brown, with painting of elongate, inosculating
black veins; whirls six convex, regularly (but slowly)
increasing; apex a little obtuse; suture moderately impressed,
not emarginate; aperture small, sub-ovate; lip acute; columella
white, short, almost straight, truncate, terminating by a
twisted plait passing within.

This species is more cylindrical than any of its congeners,
resembling most _A. Renyi_, Newc., which is longer, not
umbilicate, more pointed at the apex, with a twisted, not
truncate columella.

From _venusta_ and _citrina_, Mighels, it varies both in
form and color. With some varieties of _picta_ it claims
analogy only in the general plan of painting. Its striking
characteristics are its blunt apex, slightly rounded whorls,
small aperture, short and white columella, umbilicus, and
general plan of coloring.

A few specimens were collected at an elevation of 7,500 feet,
on West Maui, by the Rev. M. Alexander, to whom the species is
dedicated.

Description of New Species of Marine Shells from the Coast of California.

BY WM. M. GABB.

The following are a few of the shells collected by Dr. J. G.
Cooper, of the State Geological Survey, during his explorations
along the coast of this State. The specimens are preserved in
the collection of the Survey; most of them appear to be very
rare in a living state, though I have encountered several of
them in the later Tertiary deposits, especially in the Post
Pliocene.

Shell small, fusiform, thin, aperture longer than the spire;
nuclear whorls three, smooth; normal whorls three or more,
obliquely truncated above, convex below, this truncation
is partially obsolete on the last whorl; surface closely
clathrate, except on the lower part of the last whorl where
the radiating lines become obsolete; aperture large, columella
somewhat twisted, slightly encrusted; outer lip thin, acute,
posterior sinus moderately deep and narrow, adjoining the
suture and angular at its upper corner; color, brownish white
with minute brown spots sparsely scattered, usually placed on
the larger of the revolving ribs.

Hab. Santa Catalina Island, 60 fms. Dr. Cooper.

This little shell looks not unlike the young of _Pleurotoma
Carpenteriana_, _supra_, but on a critical comparison, shows
several characters incompatible with such a reference; the
strongest of these is the peculiar shape of the posterior
sinus. In addition to this, the whorls of the present species
are much more numerous in proportion to the size, the first six
whorls of _P. Carpenteriana_ making a shell three or four times
the diameter of this one.

revolving ribs; color yellowish brown crossed by about a dozen
brown revolving bands; these bands usually cover the larger of
the concentric ribs; canal elongate, columella but slightly
twisted; umbilicus obsolete; inner lip but slightly encrusted,

the Post Pliocene of San Pedro and Santa Barbara, where some
specimens have been found an inch in height.

No. 355, Mollusca, Survey Collection.

This shell appears to be allied to the genera _Calliostoma_ and
_Thalotia_, from which it is separated by the peculiar mouth.
In the absence of the operculum, it is impossible to define its
position certainly.

internally straw yellow, shading towards the margin into a
bluish white.

The above measurements are approximate, making allowance for
the epidermis which in the dry specimen is contracted and
incurved around the margins to a width of about a tenth of an
inch.

A single specimen, fresh, though without the animal, was found
by Dr. Cooper on the shore of Santa Barbara Island.

Earthquakes in California during 1864.

BY DR. JOHN B. TRASK.

FEB. 26TH, 0 h. 40 m.—A light shock of earthquake at San
Francisco. At 5 h. 45 m. a smart shock, having three distinct
vibrations. On the day previous, an “_Electric Storm_”
prevailed between Visalia, Tulare Co., and Los Angeles, which
was very violent in its effects on the telegraph lines.

On the 27th, a heavy “Norther” commenced and continued till the
eve of the 28th. This earthquake was felt at San José, fifty
miles south, at the same hour, and was marked by two very smart
shocks following each other in quick succession.

MARCH 5TH, 8 h. 49 m.—A smart shock of earthquake at San
Francisco. The earthquake began at the above hour. The first
wave was in a direction north and south, and lasted one and
three-fourths seconds. Nearly one and a half seconds elapsed
before the second shock, which occurred at forty-nine minutes,
three seconds past eight o’clock, and had a duration of one and
one-half seconds. The motion in this shock was rotatory.

Magnetism was _not_ suspended in this nor either of the other
shocks, this year. The total length of time included in this
earthquake, was nearly 5 seconds. These observations were made
at the height of 20 feet 4 inches above the ground, but persons
situated at a greater height felt the vibrations longer and
more severely.

We have brief details of this earthquake from Santa Rosa, at
the north, to Santa Cruz at the south, and from Stockton at the
east, for which we acknowledge our obligations to the Telegraph
Company. At Santa Rosa it occurred at 8 h. 50 m. the shock was
light. At Petaluma 8 h. 50 m., also light. At Stockton _about_
9 h., shock was severe. At Santa Clara 8 h. 40 m., the shocks
were very severe. The church spires waved to and fro, and the
earthquake is reported to have continued over two minutes, with
light vibrations between the heavier waves. At Santa Cruz no
time is given.

MARCH 10TH, 14 h. 8 m.—A light shock was felt in San Francisco.

” ” 16 h. 30 m.—Another shock at San Francisco, marked by two
distinct vibrations and lasting three and one-half seconds.

MARCH 20TH, 23 h. 45 m.—A light shock of earthquake having
four distinct tremors, and occupying a little more than three
seconds.

MARCH 22D, 13 h. 0 m.—A smart shock was felt at Stockton,
causing some little commotion.

MAY 20TH, 18 h. 1 m.—A light shock of earthquake at San
Francisco. At Stockton the shock was quite severe and occurred
nine minutes later. At San José it also was very sharp. At Napa
the earthquake, which was quite severe at this place, occurred
at 18 h. 57 m. At Sacramento the shocks occurred at 18 h.: and
was very severe. There were two distinct waves felt at this
locality. This earthquake was felt as far north as Long Valley,
in Mendocino County, and was followed by two loud reports like
artillery, almost instantly.

JUNE 6TH, 11 h. 7 m.—A light shock of earthquake at San
Francisco.

JUNE 22D, 20 h. 53 m.—A smart shock of earthquake at San
Francisco, consisting of three distinct waves and a profound
low rumbling sound. Each of the shocks were marked by a
peculiar abruptness, like sudden sharp jolts. They were
followed by a series of lessening tremors which gradually died
away.

This earthquake was felt as far north as Healdsburg, (about 80
miles distant), at Napa, at Pacheco, at Stockton, and at San
José, south of this city fifty-two miles, making a distance of
one hundred and thirty-two miles, north and south, over which
its influence was well marked.

JULY 5TH, 20 h. 3 m.—An earthquake at San Francisco, not
severe; this consisted of four distinct vibrations occurring
during a period of seven minutes. The second vibration and the
longest lasted nineteen seconds. The shortest vibration was six
seconds in length. The elapsed time between the waves varied
from forty seconds to one and one-fourth minutes.

JULY 21ST, 2 h. 7 m.—A smart shock was felt at San Francisco.

” ” 22 h. 40 m. 38 s.—A very smart shock of earthquake at San
Francisco, consisting of two waves at four seconds apart. The
direction of the motion was north thirteen degrees east. The
displacement was one and a fourth inches, at twenty feet four
inches from the ground. Pendulum suspension eighteen inches.

The earthquake was experienced at San José at the same hour,
and consisted of four strong shocks. At Stockton the earthquake
was severe, and took place twelve minutes later than at this
city. The earthquake was felt at Los Angeles, but was not very
heavy. No time is given from this latter locality.

JULY 25TH, 23 h. 56 m.—A shock of earthquake at Los Angeles.

AUG. 17TH, 22 h. 39 m.—A light shock of earthquake at Nevada
and vicinity.

AUG. 18TH, 5 h. 18 m.—A very strong shock of earthquake was
experienced at Grass Valley and Nevada, which threw down a wall
of stone and brick in the well of Dr. Fellows. This earthquake
was felt at Gibsonville at the north and at Marysville to the
west; at the latter locality it was twelve minutes later than
at Grass Valley.

SEPT. 6TH, 10 h. 3 m.—A shock of earthquake at San Francisco.

SEPT. 20TH, 11 h. 0 m.—A light shock of earthquake at San José;
it was observed at the Mission Dolores.

SEPT. 27TH, 10 h. 32 m.—A heavy shock at Mission San Juan,
Monterey Co.

OCT. 6TH, 21 h. 9 m.—A smart shock of earthquake at San
Francisco.

OCT. 14TH, 1 h. 8 m.—Two heavy shocks of earthquake were felt
at Mission San Juan, and another severe shock at 10 h. 25 m.,
the movement was from west to east.

DEC. 11TH, 20 h. 52 m.—A shock of earthquake at San Francisco.
This shock was felt at San José at 20 h. 51 m., and was
evidently more severe there than at San Francisco.

During 1864, we have had twenty-one days on which earthquakes
have occurred, and of at number there have been two days,
(March 10th and July 21st) in which more than one shock has
taken place within the twenty-four hours of each day.

The _British Colonist_, of Victoria, Vancouver Island,
furnishes the following statement:

From a gentleman who has resided on Vancouver Island for 15
years, we learn that slight earthquakes have occurred annually,
with one or two exceptions, during the entire period. Only on
one occasion (1858) does he remember experiencing a shock at
all approaching in severity that of Saturday morning, October
29th 1864. The oscillation, as on this last occasion, has
almost invariably been from west to east: and he accounts
for this, by supposing that the internal convulsion of the
earth beneath, has to find vent in the crater of Mount Baker,
situated to the east of us. This volcano has not had any
visible eruption for several years. On the last occasion, it
sent up a dense volume of smoke, and occasionally a bright
flame was seen to issue from the fiery furnace. Another old
resident informs us, that the appearance of the summit of Mount
Baker has undergone a material change within late years, giving
room for the conjecture that large portions have crumbled away
and descended into the yawning abyss of the crater which lies
between the two highest peaks.

Relating to earthquakes at San Francisco and its immediate
vicinity, we have an item of interesting information relating
to their effects at the Farrallones Islands, situated some
fifteen miles to the west of the city. It appears, upon the
testimony of the lighthouse-keeper at these Islands, and who
has resided there for several years, (seven or eight), that but
_two_ of the whole number occurring at this city, have been
felt at the Islands, and of these he made an official record.
The first was the shock of Dec. 23d, 1862, and that of June
22d, 1864.

From 1857 to date, we have seven years, during which time
twenty-five shocks have been authenticated at San Francisco,
while two only of the number have been felt at the above
locality west of the city.

New Mineral Oil Regions in the Tulare Valley.

BY WILLIAM P. BLAKE.

Recent examinations of prospecting parties, have added largely
to the well-known oil-bearing portions of the State. A district
some sixty miles in length, on the inner slopes of the Coast
mountains, towards the Tulare Valley, has been found to abound
in oil springs, or indications of oil. Oil exudes from the
surface in large quantities, and collects rapidly in small pits
sunk by prospectors. The soil about these pits is very black
and saturated with oil. The gases escaping from this soil are
inflammable, and many of the prospectors have been startled to
see flames spreading over the ground, beyond their camp fires.
In digging pits about these springs, large quantities of bones
of various kinds have been thrown out, and all are wonderfully
well preserved. These bones appear chiefly those of the horse,
deer, and elk, though there are many others which I have not
been able to recognize. The teeth of the horse, sent to me,
are of unusual size, and induce the question, whether they are
not of greater antiquity than the present race of horses. I am
assured that the variety of bones and teeth of many kinds is
very great.

The oil found gives an excellent article for lubricating
purposes, and must be very similar to the oil found near
Zanesville, Ohio, according to the descriptions given of the
latter.

Note upon the occurrence of Sphene in the Granite of the Sierra Nevada.

BY WILLIAM P. BLAKE.

Sphene, in small hair-brown or amber-colored crystals, appears
to be abundantly distributed in the granite of the Sierra
Nevada. It may be found at the sources of the American River,
in the exposures of granite about Slippery Ford, and other
points, and upon the Mokelumne River, further south. The
crystals are seldom more than the thirty second part of an
inch in diameter, and are not conspicuous, but may be found in
almost any specimen of the rocks.

It appears, that this mineral is also of common occurrence
in the granite of the British Islands. In a report to the
British Association, (1863) upon the composition of the granite
of Donegal, it is stated, that the rock contains, almost
universally, small crystals of sphene, in some varieties so
abundantly, as to induce the authors of the Report to term it
“sphene granite.” It is also observed that this mineral has
long been known to exist in the granite of parts of Scotland,
and in that of Galway.

Dr. Behr read the following letters from Major Preiss, of Mazatlan, as to the efficacy of the _Euphorbia prostrata_, as a remedy for the bite of the rattlesnake and venomous insects:

Euphorbia Prostrata as a remedy for the bite of venomous animals.

BY MAJOR EDWARD PREISS.

Mazatlan, January 7th, 1865.

...I send you herewith a sample of Gollindrinera, (Spanish,)
_Euphorbia prostrata_, (Linn.) It is found growing in the
territories of New Mexico and Arizona, in the United States,
and the provinces of Sonora and Sinaloa, in Mexico. In Jalisco
this plant is more scarce, and occurs mostly in a poor
condition.

It thrives in hard, sandy or stony soil, and therefore is most
frequently found on roadsides, in the streets of villages and
in house-yards. In Mazatlan I found a plant with branches,
measuring two feet.

It is a remedy against the bites of snakes and other venomous
animals.

During my voyage in New Mexico, I camped on the 5th of June,
1864, at noon, between Cubera and Pawate, near a waterhole. A
Pueblo-Indian approached me, and entered into a conversation.
He could read and write Spanish, and was very well versed on
the map of the country. Noticing a snake in the waterhole, I
asked him whether there were many rattlesnakes in those parts,
to which he gave an affirmative answer. On questioning him
whether Indians frequently died from snake-bites, he answered:
“No, as they have an antidote against the poison.” At my
request, accompanied by a gift of some cigarritos, he brought
me a plant, which he gathered from the roadside, and which he
called “Gollindrinera.” He told me that nobody ever died, not
even from the bite of a rattlesnake, if this plant was applied
in time. At the same time he told how it was used.

In Mexico I also found the country people well acquainted with
the property of this plant. They apply it when their domestic
animals are injured by venomous amphibia or insects.

The branches and roots of this plant contain a quantity of
a milky sap. This is obtained by pounding and squeezing the
plant, and is given to the patient in doses of about one
drachm. The remaining fibres of the pressed-out plant are
externally applied on the wound. The dose is repeated every
hour,—or in aggravated cases, every half hour,—until the
patient feels relieved; which will occur in a few hours. The
external application must be frequently renewed.

I ascertained from reliable authority, that two dogs, being
bitten by rattlesnakes, were cured, one after four, and the
other after six repetitions of the dose. The poultice was
frequently changed. Both dogs were perfectly restored within
twenty-four hours.

Tepic, March 28th, 1865.

...Myself and companion arrived on the 14th of March, 1865,
at 3 o’clock P. M., at San Blas. In the evening, our faces,
necks and hands were badly bitten by myriads of sandflies. The
sting of these flies is exceedingly painful, and the effects of
them last for several days. Every person visiting San Blas will
not easily forget these insects; each sting produces a reddish
swelling, which hardens after awhile, and sometimes remains for
eight days and more. We left San Blas on the 15th of March, at
1.30 A. M., and arrived at 5 P. M. at Tepic. The fly-bites were
excruciatingly painful. On the 16th we used liquid ammoniac to
allay our suffering, but without result. In the forenoon of
the 17th I found two small Gollindrinera plants in the streets
of Tepic; I pulled it, roots and all, from the ground, broke
them into several parts, and rubbed the milky juice over my
sores. In half an hour all the pain had left. Not being able
to find any more of the plants, my companion had to suffer for
several days longer; which proves, however, that my relief from
the tormenting pain was directly to be credited to the medical
virtue of the Gollindrinera.

During my lengthened stay among the natives of Australia,
I observed that no black man ever died from the bite of
a venomous reptile,—excepting always the dead-adder,
(bothrops)—while a white man seldom escaped death. The remedy
of the blacks is very simple, consisting merely in sucking
out the wound, and in keeping awake the patient for at least
twenty-four to forty-eight hours. The dead adder (bothrops)
of Australia is probably the most poisonous reptile. A black
man, if bitten by this snake, will be abandoned to death by his
friends, they being sure that help is out of the question. I
witnessed once the death of a victim of the dead-adder.

I read in an Australian paper, that a white boy, who was bitten
in the finger by a dead-adder, had so much presence of mind, as
to chop it off with his pocket-knife. The finger had afterwards
to be regularly amputated, but the boy’s life was saved.

An interesting discussion occurred as to the characteristics of various species of trees.

Occurrence of Fossils in the Auriferous Slates of California.

BY PROF. W. H. BREWER.

I find in published _Proceedings of the Academy_, just
received, that some remarks I made at the meeting of October
3d, 1864, were not published, that I wish recorded.

In the discussion on the occurrence of fossils in the
auriferous rocks of California, I stated that fossils had been
found by the Geological Survey, in the rocks associated with
gold, along a line nearly 300 miles in length, extending from
Pitt River to the Mariposa Estate; that the associated rocks of
similar age, bearing gold, had been traced upwards of 550 miles
in the Sierra Nevadas, and that _Jurassic_ fossils had been
found in the “auriferous slates,” along a belt of 200 miles of
this distance, and that both _Jurassic_ and _Triassic_ fossils
had been found in considerable numbers near and in Genesee

Mr. Hubbard presented the following paper from Mr. W. H. Pease, of Honolulu:

On the existence of an Atoll near the west coast of America, and proof of its elevation.

BY W. HARPER PEASE, OF HONOLULU, H. I.

Having read an interesting paper by Dr. Blake, in a late number
of the _Proceedings California Academy_, on the proofs of a
recent elevation of the coast of California, it occurred to
me that I had in my note book, information unpublished on the
same subject. As it lies within the field occupied by your
Academy, I furnish it herewith for publication. My information
was gathered from a Journal kept by Lieut. Griswold,[11] (a
young gentleman of scientific taste, and a close and accurate
observer,) during a cruise off the west coast of Mexico, in
search of guano. Among the islands visited, was “Clipperton
Rock,” which is the locality I refer to.

Before giving any extract, I will state what was known of the
island.

It is situated in Lat. 10° 17’ N., Long. 109° 19’ W., and was
discovered by Capt. Clipperton, in 1705. He appears to have
sighted only the tall volcanic rock, which stands near the
south end of the island, and passed on without learning of the
existence of the island. It appears not to have been noticed
again for more than a century, so that its position, and even
its existence was doubted.

The only published account of its having been visited
since, are those by Capt. Benj. Morrell[12] and Sir Edward
Belcher.[13] The former called there during a sealing voyage,
in 1825, and gives a meagre account of it in a few lines,
remarking, that “it produces a little shrubbery and some coarse
grass, among which, I think, fresh water might be found by
digging. Among the few vegetable productions of this island,
we found a plant resembling sarsaparilla, which badly poisoned
several of the crew who handled it.”

Sir Edward Belcher, during his surveying expedition, wishing
to verify the existence and position of the island, searched
and found it. He did not land, but gives the result of his
examination from the mast-head. With other remarks, he states
that “it is a coral lagoon island, three miles long N. and
S., and the same E. and W. There are two entrances, both on
the weather side, which at high-water may be safe, but at the
moment we passed, the surf was too heavy and the reflux showed
the rocks bare. On the beach several large trees were observed,
but no living trees were seen.” (May 8, 1839.)

Lieutenant Griswold notes in his journal, as follows: “On the
6th of August, 1861, we lay on our oars, just outside the
breakers on the N. E. side. At half past six we were ashore,
shooting in on a high roller, which left us high and dry upon
the beach, with a hole stove in our bow. The beach was covered
with drift wood, and while the crew were collecting it, I
started to examine the island.

“Upon every side it is girdled by a broad barrier of coral,
about fifteen feet above the level of the ocean. There is no
entrance to the lagoon, neither does it communicate with the
ocean by subterranean passages, as the water inside is _fresh_
and _potable_. It is slightly brackish, but will appease
thirst. The ‘ROCK’ is a ragged pile of volcanic formation, on
the south end of the island, gray and splashed over with the
deposit of the birds. It is cracked and split in every possible
direction, here and there shooting into tottering pinnacles.
As you wander through the caverns and clefts, with which it is
perforated, there is an incessant splashing and dropping of
water. On the very topmost pinnacle, which I reached after
a hard climb, I found a little basin containing a couple of
buckets full. The caverns were dreary looking places, dark and
wet, and echoing to the hoarse cries of the sea-birds. The
rock, on its sides, is rounded and smoothed by the action of
the waves, at some long past time, and in many places ‘_the
walls are crusted with coral_.’

“The highest pinnacle of the rock is about 120 feet high, and
it covers, I should think, about two acres. It stands on the
edge of the lagoon, or rather within it, being connected with
the coral barrier only by a narrow isthmus of coral clinker.
Between this rock and the sea, however, the barrier, instead of
being as elsewhere, a solid platform of coral, is only a heap
of fragments, piled in winrows by the waves, 250 or 300 yards
in width. The lagoon is a quiet fresh water pond, two miles
long and about one broad, with a long spit of mud running out
into the middle of it, but elsewhere of a light green color,
which seemed to indicate a considerable depth. Its shores are
abrupt, the coral platform in most places projecting out over
water of a considerable depth. I did not find the least sign of
vegetable life upon the island.

“The only plant[14] seen, grew in considerable quantities in
the lagoon, which I pulled out of the water, where it was
growing. There is nothing but a coral platform, coral clinker
and coral sand. We found nothing to detain us and left the
island on the afternoon of the day on which we landed.”

Mr. Darwin, on his remarks on the geographical distribution of
reef-building corals, states that he could find no evidence
of their living on or near the west coast of America, and
consequently discredits the statement made by Sir Edward
Belcher; for after examining a Ms. chart of Clipperton Rock,
at the Admiralty Office, drawn by Sir Edward, came to the
conclusion that it was more of the shape of a crater. The
Island is, however, a true Atoll and has been elevated at least
100 feet.

It must have been closed since 1839, and the freshening of the
water has probably been caused by rain.
