Abstract

The common practice of most anatomy and physiology books is to present sketches and diagrams of the organs and systems of the body. It is my aim to present a similar set of illustrations as they are actually seen through the eye of a camera. To my mind, there are certain advantages to such illustrations. Firstly, the pictures show the organisms as they actually are without any distortion or accentuation to confuse the issue. Secondly, the photographs give a more direct connection to the dissection of the cat since the pictures are actual and not merely schematic. Thirdly, it is my belief that such illustrations will be a greater help to the student of anatomy in his studies.

There are however, certain disadvantages to such an endeavor. Firstly, the photographs will only be as good and as complete as the dissections from which they were made. There is no possibility of adding those parts which are frequently illustrated in schematic drawings, but which are not actually visible to the naked eye. Secondly, a great deal of difficulty is had when photographing the dissections since the tissues and organs of the cat do not exhibit much contrast, which, or course, results in a monotone photograph difficult to interpret. In my endeavor, I attempted to correct this difficulty by using shadow photography, so that the organs would separate one from another by means of their own shadows. Also, there is another great disadvantage to the photography method because of the fact that it is impossible to photography every organ and system in the cat. Photographs herein represent every organism and system which could possibly be photographed in actuality, and these are supplemented by photostatics of schematic diagrams from an atlas of the cat.
