W. H. Walmsley A B C of Photo-Micrography

Annotation

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. My earnest thanks are due, and herewith expressed, to the many kind friends who have aided' my efforts in the long ago by precept and practice. Among them I would especially name my old-time friend, Dr. A. Clifford Mercer, of Syracuse, New York, and Dr. Wm. M. Gray, of the Army Medical Museum, Washington, D. C., each of whom has so largely contributed to the advancement of photo-micrography, to its present important condition of comparative perfection. My thanks are also due, in like measure, to the publishers, whose liberality, experience and good taste have done so much toward presenting the little volume in its present attractive form. And, I may add in conclusion, that should it meet with the hoped-for approval at the hands of my readers, it will probably be followed by a much fuller and more elaborate treatise on the same subject, which has been in course of preparation for several years.
