with snakes we have a special, and very marvellous, adaptation to a certain end, which arouses admiration in a high degree in one direction, even though it may excite disgust in another. On the whole—to me, at least, who am a naturalist, with the curiosity proper to one strongly developed—there is far more of wonder and instruction, than of horror, in the scene, unless, indeed, the sufferings of the victim are prolonged, which is by no means always the case. Some of the smaller constrictors, for instance, will dart upon, and twist one or two of the first neck-coils round a rat, or other small mammal, with such lightning-like speed and dexterity, and with such tremendous strength, that death—as shown by the relaxation of the muscles, and hanging down of the limbs—is almost instantaneous, and the effect upon the mind comparable to that which would be produced by the stoop of an eagle, or the spring of a tiger. We are impressed by the speed and power, and have to admire the amazing ingenuity—one may even say the beauty—of the structural adaptation; for, after all, one should have an intellect, as well as a heart. This would soon pass into more distressing sensations, were the rat long a-killing; but in the cases to which I refer it is very soon over. The bowstring in a Turkish harem must be a lengthy process in comparison. Thus the balance of our emotions produces, or should produce, the exclamation, "How wonderful!" rather than the one, "How horrible!" but with the gull and kittiwake, only the latter is
