AND PERSONALITY 



although the male rhinoceros and the male buffalo that we 

 collected were of approximately equal weight, the brain of 

 the rhinoceros was i% times heavier than that of the 

 buffalo, the adrenal glands of the rhinoceros were nearly i% 

 times heavier than those of the buffalo, and the thyroid 

 gland of the rhinoceros was i^i times heavier than the 

 thyroid gland of the buffalo. 



The weights of the energy-controlling organs of these 

 two great animals seem to indicate that the rhinoceros can 

 execute a more formidable immediate attack than the 

 buffalo.
