Excerpt from Atlas of Nerve Cells In the most recent text-books of neurology and in the atlas of Golgi these facts have been Shown by drawings and diagrams. But all such drawings are necessarily imperfect and involve a personal element of interpretation. It has seemed to me, therefore, that a series of photographs presenting the actual appearance of neurons under the microscope would be not only of interest but also of service to students. The Golgi method lends itself very readily to the photographic process, for the cell with its dendrites and neuraxon is stained black upon a light yellowish ground, and thus is capable of giving a sharp picture. In the prepa ration of this atlas I have had the co'operation of Dr. 0. S. Strong, who has cut and stained the specimens, and of Dr. Edward Leaming, whose Skill in photography has made this work possible. Dr. Strong has been able to produce remarkably successful sections of the various parts of the nervous system, both brain and spinal cord, and has made some valuable modifications Of Golgi's methods. He has contributed a section upon the technique contain ing many original and important suggestions. In the art of photographing microscopic Speci mens Dr. Learning has been particularly successful. It can be readily imagined that the difficulties of obtaining a clear picture focussed in one plane upon the photographic plate are at times almost insuperable, the microscopist ordinarily bringing various planes into his vision by the aid of the fine adjusting screw of the instrument. By care in the selection of speci mens, by ingenious contrivances to insure a perfect focussing, and by the use Of various methods adapted to each emergency, Dr. Leaming has succeeded where others have failed. He has contributed a section of much value upon the photographic technique. The photo graphs have been reproduced in a painstaking manner by Mr. Edward Bierstadt, whose process of artotyping has been selected after a careful comparison with other methods of reproduction, and it can be justly said that they Show every detail of the original photo graphs.
