Chapter I: Preface

The many kind letters I have received from America with regard to what must be called my first crude effort at bookmaking, prompted the idea—after issuing a second and revised edition in England—of making an attempt to cater for the inhabitants of Greater Britain, which, under the able editorship of MR. EDWARD L. WILSON will, I have no doubt, meet with approbation and be useful. I have made many important additions to the last English edition.

Besides revising the English edition and incorporating in proper place such additions as I have found useful in practice, I have boiled down the best points from current publications in France and Germany, and added them.

More still, with high regard for the author, I add chapters and parts from, the _Handbuch der Chemigraphie und Photochemigraphie_, by Mr. J. O. Mörch. Thus, I believe, this work is made complete to date. All the rest must come to the worker, from industrious, careful practice.

Very rapid progress has been made in photo-reproductive processes during the past two years, and improvements are announced almost weekly. I invite all interested to keep me informed of what they discover. If I am supplied with the proper addresses I shall publish and distribute what I learn.
