Mr. Bartlett informs me that when a female Cape butfalc {Bubalus caffer) was turned into an inclosure with a bull of the same species she attacked him, and he in return pushed her about with great violence. But it was manifest to Mr. Bartlett that, had not the bull shown •dignified forbearance, he could easily have killed her by a single lateral thrust with his immense horns. The giraffe uses his short, hair-covered horns, which are rather longer in the male than in the female, in a curious manner; for,. Fig. 63.
