26 TABOO AND GENETICS 



come from the sex glands are also qualitatively 

 different, as has been repeatedly proved by 

 injections and otherwise. 



Each of these sex types, male and female, 

 varies somewhat within itself, as is true of 

 everything living. The two are not so far apart 

 but that they may overlap occasionally in some 

 details. For instance, some women are larger 

 than are some men — have lower pitched voices, 

 etc. The whole bodily metabolism, resting as 

 it does upon a chemical complex, is obviously 

 more like the male average in some women than 

 it is in others, and vicg versa. But the average 

 physical make-up which we find associated with 

 the male and female sex glands, respectively, is 

 distinctive in each case, and a vast majority of 

 individuals of each sex conform nearly enough 

 to the average so that classification presents 

 no difficulty. 



The extreme as well as the average body 

 types existing in the presence of the respective 

 types of sex-glands are different. For example, 

 we find an occasional hen with male spurs, comb 

 or wattles, though she is a normal female in every 

 other respect, and lays eggs. (4.) But we never 

 find a functional female (which lays eggs) with 

 all the typical characteristics of the male body. 

 Body variation can go only so far in the presence 

 of each type of primary sexuality (i.e., sex- 

 glands) .
