Her Majesty had one from Islay, a faithful and affectionate creature, yet with all the spirit and determination that belongs to his breed. The writer of this account had occasion to operate on this poor fellow, who had been bitten under somewhat suspicious circumstances. He submitted without a cry or a struggle, and seemed to be perfectly aware that we should not put him to pain without having some good purpose in view. A third species of terrier is of a considerably larger bulk, and three or four inches taller than either of the others. Its hair is shorter than that of the other breeds, and is hard and wiry. THE SHOCK-DOG is traced by Buffon, but somewhat erroneously, to a mixture of the small Danish dog and the pug. The head is round, the eyes large, but somewhat concealed by its long and curly hair, the tail curved and bent forward. The muzzle resembles that of the pug. It is of small size, and is used in this country and on the Continent as a lap-dog. It is very properly described by the author of "The Field Book" as a useless little animal, seeming to possess no other quality than that of a faithful attachment to his mistress. THE ARTOIS DOG with his short, flat muzzle, is a produce of the shock-dog and the pug. He has nothing peculiar to recommend him. THE ANDALUSIAN, OR ALICANT DOG, has the short muzzle of the pug with the long hair of the spaniel. THE EGYPTIAN AND BARBARY DOG, according to Cuvier, has a very thick and round head, the ears erect at the base, large and movable, and carried horizontally, the skin nearly naked, and black or dark flesh-colour, with large patches of brown. A sub-variety has a kind of mane behind the head, formed of long stiff hairs. Buffon imagines that the shepherd's dog--transported to different climates, and acquiring different habits--was the ancestor of the various species with which almost every country abounds; but whence they originally came it is impossible to say. They vary in their size, their colour, their attitude, their usual exterior, and their strangely different interior construction. Transported into various climates, they are necessarily submitted to the influence of heat and cold, and of food more or less abundant and more or less suitable to their natural organization; but the reason or the derivation of these differences of structure it is not always easy to explain.
