GLANDS AS AN INTERLOCKING DIRECTORATE 111 



parental prepotent glands. If they are of the same type, they 

 may reinforce each other: if not, inhibitions and compensations 

 will come into play. Mendelian laws may apply. 



7. The process of evolution, as the play of natural selection 

 upon these variations, becomes comprehensible from a new stand- 

 point. 



8. Certain diseases, and disease tendencies, both acute and 

 constitutional, as well as traits of temperament and character, 

 and predetermined reactions to certain recurring situations in 

 life, are rooted in the glandular soils that compose the stuff of 

 the individual. 



9. The subconscious, of which the vegetative apparatus is 

 the physical basis, leads back to the internal secretions for the 

 profoundest springs of its secrets. We shall see how and why. 



10. Given the internal secretory composition, so to speak, of 

 an individual — his endocrine formula — and so his intravisceral 

 pressures, one may predict, within limits, his physical and psychic 

 make-up, the general lines of his life, diseases, tastes, idiosyn- 

 crasies and habits. 



11. Within limits, if the previous history of an individual is 

 known, his physical appearance may be approximately described, 

 and his future outlined. 



12. Conversely, given the physical and psychic composition 

 of an individual, and his past history, one may deduce the in- 

 ternal secretion type to which he belongs.
