are constitutional, inborn not made. They 

 are intrinsic, not tacked on ; of ancient origin 

 and therefore not liable to change quickly. 

 They have a deep naturalness, and attempts 

 to minimise them are not likely to spell pro- 

 gress. Some are trivial, some important; 

 but they appear to be correlated. They are 

 expressions which have from time to time 

 been given to a deep organic difference 

 between the sexes. They go through and 

 through pervasively. As Havelock Ellis says : 

 " A man is a man to his very thumbs and a 

 woman is a woman down to her little toes." 

 It is said that woman's eyelashes are in 

 diameter a third thicker than man's. The 

 differences can be read in the proportions 

 of the body ; in the composition of the blood ; 

 in the number of red blood corpuscles; in 

 the pulse ; in the periodicity of growth ; and 

 in the amount of salt in the composition of 

 the body. 



There is a whole series of anatomical facts 

 which support the generalisation that in 

 certain respects man's body is more specialised, 

 going further away from the youthful and 

 primitive type. This cannot be explained 

 away as wholly due to difference in activities. 

 It is partly connected with the fact that man 

 is longer in reaching maturity. 



Ranke notes that the typical female form 

 has a relatively longer trunk, shorter arms, 

 legs, hands, and feet; relatively to the short 

 upper arms still shorter forearms, and rela- 

 tively to short thighs still shorter lower legs, 

 and relatively to the whole short upper
