74 TABOO AND GENETICS 



sheep, Goldschmidt found it took six doses of 

 maleness to completely express it on a female 

 basis in his moths. But even with three doses, 

 the female was incapable of reproduction. A 

 single dose in excess of the ordinary combination 

 to produce normal females modified the type 

 of body, also reducing the number of eggs. 



In the case of the horns, only two types were 

 possible, absence or presence of the character. 

 Likewise there are only two types of primary 

 sex, i.e., of sex glands proper. But seven 

 different types or grades of body for each sex 

 were found to exhibit themselves in the moths. 

 In more complicated bodies, we should of course 

 expect many more, and where many races 

 (instead of two) are mixed, as in man, a classifi- 

 cation merely on the basis of physical charac- 

 teristics would be much more complicated. 

 Indeed, we may well be sceptical as to the 

 possibilities of cataloguing differences of the 

 sort between men and women by body type 

 alone. 



In society, however, we are much more 

 interested in the mental than the purely physical 

 qualities of the two types of bodies, especially 

 since the use of machines has so largely replaced 

 brute strength with skill. Most employments 

 do not even require a muscular skill beyond 

 that possessed by ordinary individuals of both 

 sexes.
