AND PERSONALITY 



In our dissections of these high-powered, long-distance- 

 running animals, we found the long muscles beginning near 

 the middle of the spinal column growing wider as the 

 muscles passed down over the rump. This superb muscle 

 mass is adapted to make the most powerful and the most 

 complete contractions, thereby propelling the animal for- 

 ward with a high speed. 



Just as a perfectly made airplane, battleship, or motor 

 car will exhibit a harmony of relations of each part that 

 contributes to the whole mechanism, so in these sense- 

 driven, bounding antelopes there was exhibited a harmony 

 of sense and energy organs in relation to the muscles. 



Our studies of herd animals also revealed a uniformity in 

 the adrenal-thyroid pattern throughout growth to the 

 adult state and, as a corollary, we found the behavior of the 

 young of the herd analogous to that of the adult member 

 of the herd. In line-bred animals phylogeny and ontogeny 

 are identical. 



The domestic animals have inherited this identical 

 adrenal-thyroid energy pattern from their wild ancestors, 

 but man has modified this pattern through breeding to 

 serve his purpose, although to the biologic disadvantage of 

 the domestic animals. 



Thomson's Gazelle 



The fact that recapitulation of behavior in the young is 

 identical with that of the adult in line-bred animals, in 

 contrast to the helplessness of the young of man, is well 

 illustrated by a picture of a three-weeks-old African baby 

 uninfluenced by struggle and survival and a three-weeks-old 

 Thomson's gazelle in which natural selection had stepped 

 up the brain-heart-thyroid-adrenal-sympathetic system to 

 such a point of perfection that this little Tommie (Thom- 

 son's gazelle), unaided by its mother, was able to escape 

 from the carnivorous enemies of the herd. This young and 

 toddling antelope was presented to Mrs. Crile. Though
