AND PERSONALITY 



field we weighed not only each of the 220 animals that we 

 studied but also every organ of each animal and sometimes 

 the skins and the skeletons. 



Routinely, all animals except the largest were brought 

 into our field laboratory, where they were weighed. The 

 skin and every organ of the body were weighed separately. 

 In large animals that had to be weighed in sections, an 

 allowance of 5 per cent was made for the blood. In all 

 instances we collected the brain and pituitary gland, the 

 eyes, the thyroid gland, the adrenal glands, the celiac 

 ganglia and sympathetic complex, the heart, the kidneys, 

 the lungs, the liver, the genitalia, often the spleen, and a 

 section of the larynx and trachea. 



In the case of large animals such as the buffalo, the 

 rhinoceros, the giraffe, the hippopotamus, and the elephant, 

 we set up scales in the field, where we carried out the dissec- 

 tions on the same plan that we followed in the field labo- 

 ratory. In the case of the elephant it was necessary to weigh 

 176 different parcels in the course of the dissection in order 

 to determine the entire weight of 14,640 pounds. 



In the Museum of Intelligence, Power, and Personality 

 of the Cleveland Clinic Foundation the heads of these 

 animals and, in some cases, the whole animals have been 

 mounted, and grouped about them are models of their 

 energy-controlling organs. 



Since the striking difference between the energy release 

 of the cold-blooded alligator or crocodile and the warm- 

 blooded lion or tiger of the same weight, of the fish and of 

 the warm-blooded bird was still to be explained, during the 

 winter of 1937 we set up a field laboratory in a cabana on 

 the beach at Key West, Florida. 



Here, besides studying many varieties of birds and small 

 mammals, Dr. Quiring, Mrs. Crile, and I studied various 

 species of fish, those that prey and those that are preyed 

 upon. We contrasted the cold-blooded shark with the warm- 

 blooded porpoise of the same weight. We discussed the
