Anecdotes of the Habits and Instinct of Animals

How it begins

Formed like man, and practicing similar gestures, but with thumbs instead of great toes upon their feet, and with so narrow a heel-bone, that even those who constantly walk upright have not the firm and dignified step of human beings; the Quadrumana yet approximate so closely to us, that they demand the first place in a book devoted principally to the intellectual (whether it be reason or instinct) history of animals. This approximation is a matter of amusement to some; but to the larger portion of mankind, I should say, it is a source of disgust.
