2o MAN IN THE ENERGY SCALE 



IF THE constant tempo of the brain is governed by one 

 gland only the thyroid gland it would follow that 

 an animal that must work at a high tempo continuously 

 and keep its metabolic fires burning at a high level to 

 protect its warm-blooded state against constant cold would 

 be equipped with a larger or more active thyroid gland than 

 the warm-blooded animal. Such animals in the sea are the 

 whale, the porpoise, the walrus. 



On land, the only animal with such requirements is that 

 animal which covers the earth, that animal which works 

 physically, mentally, and emotionally all day and worries 

 all night civilized man. According to the power formula, 

 the brain and the thyroid gland and no other organ of 

 man bears a higher ratio to his body weight than is seen in 

 any other animal. 



In addition to the provision for maintaining the constant 

 tempo of energy in man and animals, there is a provision 

 for emergency energy. Emergency energy is preeminently 

 required by the lion and the other members of the cat 

 family in their explosive attack, by the escaping rodents 

 and hoofed animals, by the wild animals on the land and 

 the birds in the air. All are evolved in a greater or lesser 

 degree to execute flash energy in attack and in escape. 



The mechanism that executes flash energy is the brain, 

 the heart, the adrenal glands, the celiac ganglia and 

 plexuses, and the sympathetic system. The energy charac- 

 teristics of what we call the "wild" state are the result of 

 the emergency power of the specific action of adrenalin and 

 sympathin, each of which profoundly affects the brain and 

 the sympathetic system. The activation of the adrenal- 

 sympathetic system affects every cell in the body more 

 intensively in the lower animals than in the lower races of 

 man, more intensively in the lower races of man than in the
