Abstract
Summary
1. It is confirmed in the dog, as has been shown for other species, that the relative weight of the hypophysis is greater in adult females than in adult males, and that this difference does not exist before maturity. 2. The hypophysis weight-body weight ratio of puppies is greater than that of adult dogs, and in adult dogs decreases significantly with increase in body size. 3. Relative hypophysis weight was smaller in senile than in adult animals. 4. No sex difference in hypophysis weight existed within any weight-group of adult animals. 5. No differences between groups could be detected with respect to water content of the hypophysis.
