He's got his own character and his own experience.

All lions have ways in common because they're built alike.

They're heavy and muscular because they've got to pull down big game; and because they're heavy they move slowly, and because they move slowly they've got to adopt common tactics in hunting.

Good; but one lion differs from another, and so with other animals, right away through the list.

So, I say, one must study the personal habits of animals in their own back yard, so to say, before he can give a true description of them.
