animals caught in a trap or enclosure attacking and 
destroying each other in their frenzy ; and the fact 
that some fierce-tempered carnivorous mammals 
will devour the companion they have killed. It is 
an instinet of animals like wolves and peccaries to 
devour the enemy they have overcome and slain: 
thus, when the jaguar captures a peccary out of a

first place of attacking and killing it. In no other 
circumstances, not even when starving, do they prey 
on their own species. 
If the explanation I have offered should seem a 
true or highly probable one, it will, I feel sure,

regarding this seemingly ruthless instinct, not as 
an aberration but as in some vague way advantage- 
ous to animals in their struggle for existence, are 
yet unable to think of it without pain and horror ; 
indeed, I know those who refuse to think of it at

It should be arelief to them to be able to look on 
it no longer as something ugly and hateful, a blot 
on nature, but as an illusion, a mistake, an un- 
conscious crime, so to speak, that has for its motive 
the noblest passion that animals know—that sub- 
lime courage and daring which they exhibit in 
defence of a distressed companion. This fiery spirit
