134 THE GLANDS REGULATING PERSONALITY 



expression. That is to say, that just as a precipitate of chalk 

 is formed when one throws some carbonate of soda into lime 

 water, so the masculine and the feminine are to be looked upon 

 as precipitates and crystallizations of a long series of linked 

 chemical reactions in the fluids of the body, in which the inter- 

 nal secretions play a determining part. 



2. Femininity and masculinity are expressions of the inter- 

 play of all the internal secretions. It used to be said by smart cats 

 and accepted by the tabby cats, that a woman was a woman 

 because of her ovaries alone. It is being said by some great 

 discoverers of the day that man is a man because of his testes 

 alone. Neither of these dogmas is true. There are individuals 

 with ovaries who show every deviation from the feminine and 

 there are individuals with testes who exhibit every variation from 

 the masculine. The other endocrine glands are of equal impor- 

 tance. 



3. There is no absolute masculine or absolute feminine. The 

 ideals of the Manly Man and the Womanly Woman were erected 

 by the blind ignorance of the nineteenth century illusionists, and 

 a line drawn to cleave them. But indeed biologically there exists 

 every transition between the masculine and the feminine. The 

 explanation of these different sex types consists in the dif- 

 ferent admixtures of the internal secretions possible and 

 actual. When we speak of the feminine we really mean the pre- 

 dominantly feminine. And when we speak of the masculine, we 

 mean the mainly masculine. Between, all sorts of transitions 

 are possible and occur. 



Man in relation to the internal secretions we have considered 

 in reviewing the interstitial cells. To him, we shall return later. 

 Let us turn now to that fascinating subject of the ages, Woman. 

 What produces and maintains the Feminine? 



The Cause of Sex 



To all appearances, that inscrutable simplest of living things, 

 the fertilized ovum, beginning of the human, starts bisexual, 

 double sexed, both masculine and feminine, or perhaps neither 

 masculine nor feminine. Then a form develops. Then within 

 that form a patch of cells arise which the microscopist recog- 

 nizes as the forerunners of the male or the female reproductive 

 cells. Then some more development. And at birth, sex is 

 definitely settled, as far as the reproductive organs are concerned.
