Abnormal Findings in 246 Consecutive Autopsies on Monkeys *

Between December 1, 1938, and April 1, 1940, autopsy examinations have been made of 246 subhuman primates in the Laboratory of Physiology of the Yale University School of Medicine.t These routine examinations were made in order to obtain some normal and abnormal values for monkeys of those species most commonly used in laboratory experimentation. It was expected thereby to establish some standards for factors in health and disease, such as: size and weight of organs, normal variations, the incidence of infection, infestation, and developmental anomaly. The normal findings for weights and the descriptions of organs are published elsewhere.7 The present paper deals only with the grossly abnormal findings.
