 the female among the lower animals runs more 

 smoothly and evenly — is more on the order of the 

 neutral tint — than is that of the male. The females 

 of the same group dififer from one another much

 mission that makes him more restless, feverish, and 

 pugnacious. He is literally "spoiling for a fight" 

 most of the time. This surplusage, these loaded 

 dice, make the game pretty sure. 



Cut o£E the ugly bull's horns, and you have tamed 

 him. Castration tames him still more, and changes 

 his whole growth and development, making him 

 approximate in form and disposition to the female. 

 I fancy that the same treatment would have the 

 same effect upon the peacock, or the bird of para- 

 dise, or any other bird of fantastic plumage and

 gay and the ornate, should have played any con- 

 siderable part in superinducing these things.
