An ape will be an ape, though clad in purple.

Who hears the fishes when they cry?

Of all the creatures that breathe and creep on the surface of the earth, none is more to be pitied than man.

Histories are more full of examples of the fidelity of dogs than of friends.

Every creature in the world is like a book and a picture, to us, and a mirror.

Animals are such agreeable friends—they ask no questions, they pass no criticisms.

The elephant, although a gross beast, is yet the most decent and most sensible of any other upon earth.
