Histochemical, biochemical, and electron microscopic investigations on resected specimen have expanded in almost exponential manner in the past ten years and taking photograph of the specimens is also of importance for the examination of them. The specimens are, however, damaged during the time of taking photograph by various factors such as heat, dryness, light etc. For the investigations of this kind, the most important requirement for preservation of protoplasmic structure is to interrupt the dynamic process of the cell as prompt as possible and to stabilize the structure with a minimum of change. To prevent the damage of the specimens during the time of taking photograph, the following procedure is proposed: The specimen is dipped into cold saline solution, phosphate buffer, or cacodylate buffer. as soon as possible after operation. Photographic procedure is carried out upon the specimen dipped into the solution. By this procedure, the specimens can be protected from being damaged by heating and drying. Furthermore, the specimen can be preserved in its original shape due to the aid of buoyancy. This procedure has an another advantage : The photograph is in principle free from halation on the surface of the specimens. Thus, the proposed procedure is very useful for taking photograph of resected specimens in general
