AND PERSONALITY 



a high-energy equipment in order to maintain their warm- 

 blooded state and to enable them to exercise their ability 

 in securing food. 



Then what of the high-tempered zebra that lives in the 

 hot tropics ? We may as well ask what of the highly ener- 

 gized lion, the leaping leopard, the wild dog, the impala, 

 the wildebeest in fact, the entire antelope family in the 

 tropics. 



The answer for the lion, the tiger, the leopard, the wild 

 dog is that they are obliged to chase high-tempered food. 

 To catch such highly energized food, the carnivores must 

 themselves rush and spring and pursue in order to live. 

 So, too, must the antelopes, the great eland, the water- 

 buck, the wildebeest, and the zebra be bred not for climate 

 but for escape. 



For aeons the zebra, like all wild horses, has been bred 

 by the lion, the leopard, and the pursuing pack. The energy 

 system of the zebra has been adapted not to climate but to 

 escape. 



But what of the ass ? True asses differ little from the 

 zebra, save in their coats. Whether from Africa or Asia, 

 the ass has been long subjected to the lion's rush, the 

 leopard's spring, and the carnivore's pack. Judging from 

 its energy system alone, as shown by its ratios, it is evident 

 that somewhere along the line the ass must have been bred 

 either in the high plateaus along with the mountain sheep 

 or goats, where food was scarce, or in the more individual- 

 istic background of the deserts, where the supply of food 

 was meager and water holes far apart, thus making it 

 possible for the ass to become adapted to restricted food 

 and drink. 



The ratio of the weight of the brain of the ass to his 

 body weight is 1:530, as compared with 1:645 for Equi- 

 poise. According to the power formula, the values for 

 the ass, as compared with those for Equipoise, are as 

 follows :
