Body weight, the weight of twenty three organs, and their ratio to the body weight of twenty (sixteen males and four females) wild Japanese monkeys (Macaca fuscata) were measured and recorded. The length of intestinal subdivisions of each monkey was also recorded. Similar measurement of six (four males and two females) captive born Formosan monkeys (Macaca cyclopis) was also added to be compared. Roughly speaking, the change of organ weights with increasing age of monkeys could be classified into five types.
