HOW GLANDS INFLUENCE THE NORMAL BODY 115 



internal secretion theory. It has long been known that certain 

 diseases effect only certain individuals of a definite constitution. 

 Apoplexy, diabetes, arteriosclerosis, Bright's disease, are met 

 with almost exclusively in what the older clinicians talked about 

 as the apopleptic type. On the other hand, they said, anemias, 

 tuberculosis, hemophilias, scrofulas occurred more among the 

 lymphatic type. But they had no idea whatever of the true func- 

 tional basis of the two different types. The truth as we of today 

 view it is that these two types represent different textures of 

 human beings, fabricated of different internal secretions. They 

 are really two different breeds of the species Homo Sapiens. 

 The materials being different, the color and feel of them is 

 different, and the resistance to wear and tear is different. 



Endocrine Analysis 



The modes of classification glimpsed at are certainly exceed- 

 ingly broad and sweeping. It is well enough to establish types 

 and classes. But beneath them are sheltered the infinite possi- 

 bilities of permutations and combinations, which explain the 

 countless variety and complexity of form and function. Every 

 individual born among the vertebrates, for example, must have 

 a certain definite amount and percentage of pituitary gland, 

 anterior and posterior, pineal, thyroid, parathyroid, thymus, 

 adrenal, pancreas, interstitial and so on. Now if, to state it in 

 terms of percentages, for the sake of argument, the pituitary is 

 25, the pineal 10, the thyroid 36, the parathyroids 15, the thymus 

 29, the adrenals 60, the pancreas 49, the interstitials 72 (the 

 gland when acting maximally to be graded as 100), we see at 

 once how different such an individual must be from one who has, 

 say, pituitary 84, pineal 39, thyroid 26, parathyroid 42, adrenals 

 96, pancreas 22 and interstitials 89. One obtains at once from 

 the contrasts of such figures some idea of the possibilities. As 

 each point plus or minus must count to produce some difference 

 in the individual, the results are manifest. Varying within the 

 numerical limits imposed by genus, species, variety and family 

 (which limits are probably responsible for the persistence of the 

 particular genus, species, variety, or family) the individual be- 

 comes an individual because of the relative values of the per- 

 centages in his blood and tissues of these different internal secre- 

 tions. We thus begin to gain an insight into the patterns accord- 

 ing to which men, women and animals are woven.
