"Animals destitute of reason live with their own kind in a state of social amity. Elephants herd together; sheep and swine feed in flocks; cranes and crows take their flight in troops; storks have their public meetings to consult previously to their emigration, and feed their parents when unable to feed themselves; dolphins defend each other by mutual assistance; and everybody knows, that both ants and bees have respectively established by general agreement, a little friendly community."
