AND PERSONALITY 



lion and the tiger. The more highly specialized an animal is 

 for a rushing attack the more the adrenal glands and celiac 

 ganglia will dominate. On the other hand, in proportion to 

 adaptation for pursuit, the less will be the preponderance 

 of the adrenal glands and celiac ganglia. 



Applied to the comparison between the lion and the tiger, 

 we have the following studies of individual animals of 

 comparable weight, which suggest that the lion is more 

 highly equipped for a rushing attack than the tiger. 



The Heart of a Lion 



There is a current opinion that the lion possesses a heart 

 of unusual size. This is not supported by facts, as may be 

 seen in the table that follows. 



It will be seen that the heart of the rushing lion in the 

 wild state is not so large as the heart of many of the long- 

 endurance running animals. 



The adrenal glands of a lion in the wild state are 25 per 

 cent heavier than those of a lion of approximately the same 

 body weight in captivity.
