While reading Les Misérables I found this

"It is our conviction that if souls were visible to the eye we would clearly see the strange fact that each individual of the human species corresponds to some species of the animal kingdom; and we would easily recognize the truth,scarcely preceived by thinkers, that from the oyster to the eagle, from the pig to the tiger, all animals are in man and that each of them is in each man; sometimes several of them at a time." (Hugo 169)

That really stuck out to me, and it amused me as well. Seems that Therianthropy isn't as young as some might have you believe *grins.*
