it is worthy of note that the mesial section of the chimpan- 

 zee's pelvis showed that the layer of subcutaneous fat in front 

 of the pelvis was about three times as thick as that on the 

 anterior abdominal wall. The labia majora are rudimentary, 

 and do not conceal the labia minora and clitoris. All autho- 

 rities agree in recognising the large size of the clitoris ; but 

 there is a point in connection with the position of this organ 

 to which I can find no reference. The two crura are attached 

 to the sides of the pubic arch, and, passing forwards and 

 upwards, unite at the lower edge of the pubic symphyses to 

 form the body of the clitoris, which passes at once down- 

 wards and backwards {see Fig. 2). In the human subject the 

 two crura are prolonged upwards in front of the pubis, and 

 unite to form the body of the clitoris anterior to and about 

 midway between the upper and lower edges of the symphyses 

 {see Fig. 3). Tlie clitoris thus occupies a higher and more 

 anterior position in relation to the symphyses in the human 

 female than in the chimpanzee. 



In both my specimens the glans clitoridis was flattened 

 from before backwards, and projected considerably beyond 

 the prepuce. Behind the clitoris was the opening of a 

 distinct uro-genital canal. This passage was connected 

 above with the urethra and vagina, and passed downwards 

 and backwards. It was half an inch long in one specimen, 

 and three-quarters of an inch in the other. 



Bischoff^ stated that the female genitals in the human 

 subject presented numerous features in which they differed 

 from those of the anthropoids, and he maintained that 

 Huxley's proposition that the differences between man and 

 the anthropoid apes were less than those between the latter 

 and the lower monkeys was not true so far as the female 

 genitals were concerned. 



There can be no question but that the differences between 

 the relations of the external genitals in the chimpanzee and 

 in the human subject are very marked. This is very evident
