SUMMARY1 Comparisons have been made between fifty‐eight dimensions of the milk teeth of (a) the male and female chimpanzee, (b) the male and female gorilla. 2 There is no evidence that the milk teeth of the male chimpanzee differ in size from those of the female. 3 The milk teeth of the male gorilla are, on the average, 3 per cent bigger than those of the female. 4 These differences appear before the hormonal factors responsible for the pubertal growth spurt become operative, and may be controlled genetically.
