that are most highly hybridized. Therefore, the greatest 

 incidence of mutations is found in civilized man and in 

 the thoroughbred horse. Mutations are rarely seen in 

 line-bred animals in the wild state. In the case of civilized 

 man the principle of natural selection is suspended. In 

 the case of the thoroughbred horse the principle of natural 

 selection is also suspended, not by the horse but by the 

 mind of man. 



In civilized man there is seen the extreme development of 

 the thinking brain, the thyroid gland, and the manipulative 

 hand. Through mutation the mechanism that has em- 

 powered man to develop energy outside himself has evolved 

 to the highest degree, as seen by the ceiling of energy dis- 

 eases that interferes with the further progress of civilized 

 man. Since civilized man depends on animals and machines 

 to do much of his work, the mechanism of man for outburst 

 energy has diminished, whereas the thoroughbred horse, in 

 order to win a race, has been evolved by man for the 

 highest degree of outburst energy. Thus these two most 

 highly hybridized animals, civilized man and the thorough- 

 bred horse, have been developed to a high degree but toward 

 opposite energy principles, the thoroughbred horse in the 

 equipment for the wild state, civilized man in the equip- 

 ment for the machine age of the civilized state. 



Mutations are usually most striking in the organs that 

 have the greatest significance to the animal. In man the 

 organs of highest significance are the thinking brain and 

 the central nervous system. In the thoroughbred horse the 

 organs of highest significance are the brain, the heart, and 

 the adrenal-sympathetic system. In the case of man the 

 mutation of the brain is shown by the fact that there are 

 over half a million hospital beds for nervous and mental 

 diseases in the United States alone. 



Brown Eyes, a thoroughbred horse, was as well bred as 

 the famous racing stallion Equipoise. Brown Eyes had been 

 trained in one of the outstanding racing stables in Ken-
