AND PERSONALITY 



bear its own weight in the mud-water medium as it lies in 

 wait to entrap its prey, and a lion, an animal possessing 

 the most fulminating energy known, is seen in the contrast 

 of the energy-controlling organs of these two animals. The 

 weight of these two animals was approximately the same, 

 the weight of the lion being 430 pounds and that of the 

 alligator, 450 pounds. Both animals are carnivorous. Note 

 the brain of the lion. It weighs 261 grams, whereas the 

 brain of the alligator weighs only 14.08 grams (Fig. 2). 

 Note, also, the thyroid glands that maintain the constant 

 level of oxidation. The thyroid gland of the lion weighs 

 22.52 grams; the thyroid gland of the alligator weighs 13.32 

 grams. 



Note the adrenal glands that execute crisis energy. The 

 adrenal glands of the lion weigh 34.64 grams; the adrenal 

 glands of the alligator weigh 11.96 grams. The heart of the 

 lion weighs 1,175 grams; the heart of the alligator weighs 

 318.4 grams. 



In Fig. 3 note the striking contrast between the com- 

 plicated network, the mass of interlacing nerves, the large 

 celiac ganglia and plexuses of the adrenal-sympathetic 

 system of the lion and the simplicity of this mechanism 

 and the absence of the celiac ganglia and aortic plexuses in 

 the alligator. In the lion, on each side, eighty-two nerves 

 extend from this mass; in the alligator but three. 



No one could fail to see the difference in power that 

 is generated by these two mechanisms. The blueprints of a 

 tractor engine and an airplane engine could be no more 

 enlightening. Both the alligator and the crocodile are master 

 animals in their limited environment, but the master cold- 

 blooded animal shows a marked contrast to the master 

 warm-blooded animal. 



Another striking contrast between a cold-blooded animal 

 and a warm-blooded animal is seen in a comparison of the 

 energy-controlling organs of a python that we collected in 

 Africa with a sparrow that we collected in Cleveland.
