AND PERSONALITY 



tucky. All that care and skill in training could bestow had 

 been lavished on Brown Eyes. This thoroughbred horse 

 was so abnormally energized and possessed such an ex- 

 citable temperament that it was impossible for her to be 

 started in a race. Through this fact alone we were able to 

 collect the energy-controlling organs. 



The disappointing behavior of Brown Eyes was due to a 

 mutation in the size of the adrenal glands. These glands 

 were so abnormally large and the supply of the powerful 

 adrenalin that an animal must possess to have outburst 

 energy was so excessive that this animal failed through 

 mutation of the adrenal glands. Brown Eyes had the largest 

 adrenal glands found in 231 horses dissected by us. Let us 

 now turn to an analogy in the human race. 



A gangster twenty-five years of age, convicted of murder, 

 had been as impossible to control as was Brown Eyes to 

 train. The home, the school, the church, the law, and the 

 customs of civilization itself were as powerless to make this 

 abnormal man conform to the conditions of civilized life 

 as were the breeding, the skill, and the training of the 

 famous racing stable to make the thoroughbred Brown 

 Eyes conform to the conditions of a race. 



The adrenal glands of this gangster were twice the weight 

 of the average normal human adrenal glands. The patho- 

 logic behavior in both the thoroughbred horse and the 

 gangster would seem to be due to a mutation in the size of 

 the adrenal glands. 



In the case cited of mutation in the horse we have other 

 examples; in the case of the gangster we have no other 

 example. A single fact may depend only on chance and may 

 not be a forerunner of a law. Therefore, standing alone, 

 this case offers only a suggestion. 



Equipoise achieved the greatest racing success of his time; 

 Brown Eyes was the greatest failure. In civilized life the 

 Scotch laborer was a normal member of society; the gangster 

 was a failure.
