112 THE SEX-COMPLEX 



Mental char- deficiency in the maternal emotions. Lactation, also, 

 during 1CS incites or increases the mother-love — as poets for 

 lactation. countless ages have told us — partly by demonstrat- 

 ing, as it does, the dependence of the infant, and 

 partly by inspiring the mother with the joy of self- 

 sacrifice. 



After the menopause the mental attitude may revert 



to a more neutral type.

 Dimorphism It has already been stated that every person is

 ive proportion varies in different individuals and in 

 different characteristics ; but the dominant character- 

 istics usually indicate the declared sex of each, while the 

 recessive' characteristics remain more or less latent. 

 This being 'so in regard to structural disposition, logically 

 we may expect the functional activities to correspond 

 therewith; as, indeed, they do. It is to be regretted, 

 however, that at present we know so little of the finer 

 anatomical differences of the regulators of sex meta- 

 bolism, for, were we able to point to definite and constant 

 distinctions at all ages between the structure of the 

 organs of internal secretion other than the gonads in 

 the two sexes, it would be easier to convince those who 

 are now sceptical of the differences of function dependent 

 thereon. I believe, by reason of much physiological and 

 pathological evidence, that there are such differences, 

 and that if these cannot always be expressed qualitat- 

 ively, they certainly can quantitatively. And, after all, 

 quantity is capable of producing effects and results as 

 surely and with as great variations as quality. Further- 

 more, it must be obvious to all that normally different 

 metabolic effects are due to different demonstrations of 

 function ; and that different demonstrations of function
