As a counterpart to much of this, the ancient Hyrcanians may be mentioned, who lived near the Caspian Sea, and who deemed it one of the strongest expressions of respect to leave the corpse of their deceased friends to be torn and devoured by dogs. Every man was provided with a certain number of these animals, as a living tomb for himself at some future period, and these dogs were remarkable for their fierceness. [Not only the Hyrcanians but most of the people dwelling on or near the Caspian sea, preserved this race or a similarly formidable one, more particularly to devour their dead; it being considered more propitiatory to the Gods, and more flattering to the spirits of the deceased, to make this disposition of the corpse, than consigning it to the gloomy grave or funeral pile. This custom is noticed by Theodoret as being pursued by the inhabitants of those parts, and was not abolished till after their adherence to Christianity.--L.] DOMESTICATED DOGS OF THE FIRST DIVISION Some of the readers of this work may possibly recollect three beautiful dogs of this species in the gardens of the Zoological Society of London, which afforded a perfect illustration of the elongated head of the dogs belonging to Cuvier's first section. Mr. Bennett, the Secretary of the Society, gave an interesting account of them in 1835, derived from the observation of Sir John Franklin and Dr. Richardson. The elongation and sharpness of the muzzle, and the small capacity of the skull, first attract attention. The dog was doubtless fitted for its situation, where its duty is to hunt by sight after the moose or rein-deer, but would have been comparatively worthless if he was to be guided by the scent. Its erect ears, widened at the base and pointed at the top, gave it an appearance of vivacity and spirit. Its depth of chest, and tucked-up flank, and muscular quarters, marked it as a dog of speed, while its light frame, and the length of the toes, and wideness of web between them, seem to depict the kind of surface over which it was to bound. It is not designed to seize and to hold any animal of considerable bulk; it bounds over the snow without sinking, if the slightest crust is formed upon it, and eagerly overtakes and keeps at bay the moose or the rein-deer until the hunters arrive. This animal furnishes a beautiful illustration of adaptation for a particular purpose.
