94 THE GLANDS REGULATING PERSONALITY 



of the secretion of the islands of Langerhans in the pancreas. 

 Removal of the pancreas makes the body, essentially the liver, 

 unable to retain sugar, as well as unable to burn up sugar for 

 energy. The situation is comparable to a locomotive with its 

 coal bins leaking, and the coal itself acting as if made of slate 

 or some equally uncombustible or only partially combustible 

 material. 



The control of sugar mobilization from the liver, where it 

 is stored as glycogen or animal starch, is divided between the 

 pancreas and the adrenals, the pancreas acting as the brake, the 

 adrenals as the accelerator of the mechanism. Adrenal and pan- 

 creas are therefore direct antagonists, the pans of the scale which 

 represents sugar equilibrium in the organism. Diabetes may be 

 regarded as a disturbance of the adrenal-pancreas balance, 

 assisted by events which produce adrenal overwork like great 

 or prolonged emotion, or by strain of the pancreas, effected by 

 over-eating for example. 



There are other minor glands of internal secretions. But those 

 considered are by far the most important and the -most recently 

 explored. In a summary, one would classify them as follows: 



Name

1. Thyroid 



Thyroxin 



Gland of energy pro- 

 duction 



Controller of growth 

 of specialized or- 

 gans and tissues- 

 brain and sex 



2. Pituitary-
