all animals of the same kind. I accordingly went to the Tower with one who plays on the German flute; he began playing near four or five lions; only one of these (the rest not seeming to regard it at all) rose up, came to the front of his den, and seemed to be all attention; meantime a tyger in the same den started up, leaped over the lion's back, turned and ran under his belly, leaped over him again, and so to and fro incessantly. Can we account for this by any principle of mechanism? Can we account for it at all?" Where is the mystery? Animals are affected by music just as men are who know nothing of the theory, and, like men, some have musical ears and some have not. One dog will howl at a flute or trumpet, while another is perfectly indifferent to it. This howling is probably not the effect of pain, as the animal shews no mark of displeasure; he seems to mean it as a vocal accompaniment.
