celiac ganglia and plexuses, and the entire sympathetic 

 nervous system causes a powerful beat of the heart, a 

 speeding of the circulation of the blood, a mobilization and 

 transference of the sugar from the liver to the blood stream, 

 and a speeding of the respiration. The result is a stupendous 

 output of energy for attack that more nearly resembles an 

 explosion than a physiological act. Following such a con- 

 vulsion of activity, there is rapid exhaustion. 



On this premise, we should expect to find that the 

 adrenal glands, celiac ganglia and plexuses would bear 

 a higher ratio to the body weight in the lion and in the tiger 

 than in any other animal, wild or domestic, of comparable 

 size. Let us now turn to the record. 



In man, in the wolf, and in the dog there are two celiac 

 ganglia. In the lion and the tiger there are clusters of celiac 

 ganglia. In the lion and the tiger the celiac ganglia equal 

 the weight of the adrenal glands. This does not occur in any 

 other animal that we have dissected. On each side there are
