142 THE GLANDS REGULATING PERSONALITY 



relative capacities and potentialities, some single principle must 

 run through the making of both. 



Recognizing of course the qualifications inherent in so broad a 

 statement the answer is: the handling of the lime salts. Life or- 

 iginated, or at least lived and worked for long ages in sea water. 

 During these eras the salts of the sea have come to play a 

 dominant role in its being. The lime salts, because of their 

 peculiar properties of dissolving or precipitating themselves ac- 

 cording to electrical conditions in their medium, have come to 

 occupy a central position in all the processes of growth, metabo- 

 lism and sex differentiation. So it is that masculinity may be 

 described as a stable, constant state in the organism of lime salts, 

 and the feminine as an unstable, variable state of lime salts. The 

 male skeleton contrasts with the female as the stronger, larger, 

 heavier and straighter because it is an expression of a greater 

 capacity to utilize, store and keep lime in the system. Women 

 throughout their reproductive period are liable to rapid and 

 pendulum-like fluctuations of their lime content. 



Menstruation, pregnancy, lactation, all draw upon the stores 

 of lime, sometimes depleting them to the point of softening of 

 the bones and wrecking the whole skeleton. The endocrines 

 control the transport, and course, combinations and permutations 

 in the history of lime's progress among the cells, and are in turn 

 themselves affected by it. Man is relatively free of these liabili- 

 ties, and so remains man by his freedom from the recurrent crises 

 involving the lime salt reserve which constitute the essence of the 

 life story of woman. 



The Sex Index 



It follows from these considerations that when it becomes nec- 

 essary to size the sex composition of a man or woman, a meas- 

 urement becomes establishable which may be spoken of as the sex 

 index. To be able to say of Mr. Llewylln Jones that he is sixty 

 per cent masculine and forty per cent feminine, or of Mrs. Worth- 

 ington that she is seventy per cent feminine and thirty per cent 

 masculine would be of the utmost value under all kinds of cir- 

 cumstances. Unfortunately, lacking as we do the exact figures 

 of an advanced blood chemistry (yet in its most infantile in- 

 fancy) a direct indexing of the sort is impossible. But it is cer- 

 tainly conceivable, along the lines of measurement suggested 

 by the Binet tests and others, that a scale of evaluation of the
