pure solution, as it were—than to scatter the seed—to distribute the mixture—as one has gathered it from one's own experience and experiment. I have endeavored, however, to compile and write such matter for these pages as will make the novel, fascinating and valuable Carbon Process, plain, practical and easy to all workers in photography.

Although it will be seen by the historical notes that follow, that many carbon processes have been worked more or less, yet to Mr. Joseph Wilson Swan, New Castle-upon-Tyne, England, we are indebted for the most practical and perfect one, and to this I will ask you to give your especial attention. It is now practised considerably and successfully in this country, as our specimen will testify, and most largely abroad, by Messrs, Swan, Braun, and others.

Like many other useful discoveries, this process has been perfected only by slow degrees, and by the laborious and patient research of many individuals. As early as 1814 M. Niepce made experiments in Carbon printing, and to him it owes its origin; but after all the manifold experiments by the many who shall be named in proper place, to Mr. Swan is due the honor and praise for having simplified, perfected, and made easy of practice, a process for photographic printing, where every beauty of management and manipulation is preserved perfectly and permanently.

Those who endeavor to practise it will find it entirely different from the silver process—no gold, no silver, no
