We condense from a capital English review of M. Blazs's work on Dogs, the following chapter - which we are certain will be read with great pleasure by all our readers in the country].

The dog alone, of all the brute creation, shows a perfect attachment - alone understands our wishes, adapts himself to our habits, waits upon our commands, associates with us as a friend. The service of man, while a single link of the connexion remains, is a necessity of his existence. The Siberian dogs, set free in summer to shift for themselves, though overtasked, treated with brutality, and nearly starved, return to their masters at the approach of winter, to be harnessed to the sledge. The Pariah dog of India, when homeless and unowned, will fasten on a stranger, and exhaust every art to induce him to adopt it. Colonel Hamilton Smith tells of one that fixed his regards on a gentleman traveling rapidly in a palanquin| and continued to follow him with wistful eyes, till he dropped with fatigue* No one can question that this disposition of the dog is a peculiar gift of Providence for the benefit of our race. Other animals surpass him in beauty and strength, yet in every quarter of the globe, the dog alone is in alliance with man, because he is alone endowed with that impulse that renders him accessible to our advances, and submissive to our will.

His domestication, in the opinion of Cuvier, is the most complete, the most useful, the most singular conquest we have achieved, and perhaps, he adds, essential to the establishment of society.

The vast power and courage of certain races of the dog are truly extraordinary. The story told by Pliny of an Albanian dog of Alexander the Great, who conquered, one after another, a lion and an elephant, is probably a fable, like the addition of aelian, that his tail, his legs, and his head, were severally amputated without loosening his hold, or producing even an appearance of pain. As little do we credit the feats of a mastiff in the reign of Elizabeth, who was reported to have fought and beaten in succession, a bear, a leopard and a lion. But there are better grounds for believing that one of this species really engaged the king of beasts in the reign of Henry VII., who absurdly ordered him to be hanged for his presumption: and it has been frequently proved that three or four can carry off the victory. Colonel Hamilton Smith was witness of a scene between a bull-dog and a bison, in which the former seized the latter by the nose, and kept his hold till the infuriated animal crushed him to death. The terrier grapples with beasts of twenty times his size, and, however cruelly mangled, dies without a groan. It is thus that the dog, who provides the savage with food by his swiftness, protects him by his bravery. Such prowess and endurance belong to few of our domestic breeds.

But nature develops the faculties which the occasion demands. The dogs that live amidst wilds and dangers are all conspicuous for hardihood, daring, and insensibility to pain. Their cunning and sagacity are in like manner proportioned to their needs. The dogs by the Nile drink while running to escape the crocodiles. When those of New-Orleans wish to cross the Mississippi, they bark at the river's edge to attract the alligators, who are no sooner drawn from their scattered haunts, and concentrated on the spot, than the dogs set off at full speed and plunge into the water higher up the stream. An Esquimaux dog, that was brought to this country, was given to artifices which are rarely seen in the native Europeans, whose subsistence does not depend on their own resources - strewing his food round him, and feigning sleep, in order to allure fowls and rats, which he never failed to add to his store.

Bat even with us, the dogs who bant on their own account, display an ingenuity which is seidom attained by those who bunt for a master. The wily lurcher, who, more than any other dog, is addicted to poaching, when he puts up a rabbit, makes for her burrow, and there awaits her arrival. M. Blaze had two dogs that hunted by stealth, of whom one started the hare, and the other, concealed behind a fence, pounced on her as she passed through her accustomed run A story is told of a pointer and a greyhound who combined together - the greyhound availing himself of the scent of the pointer to find the game, the pointer of the speed "of his associate to catch it. The pointer becoming suspected was furnished with a chain to impede his movements; and still continuing his roving life, it was at length discovered that the greyhound, in order to enable him to hunt us usual, carried the chain in his mouth, till he himself was called upon to take up the chase. The skill of the common hound, though less striking, is still proportioned to the exigencies of the service, and is something more than a mere instinct; for when a young dog is entirely at fault, one experienced in the craft, will detect the doublings of the fox or the stag, the devices to break the scent, or the attempts to divert it, by starting another animal.

It is practice which has taught him to unravel the intricacies of the chase, to distinguish between conflicting scents, to divine the rust of a fugitive that is fertile in resources. In one thing, however, old dogs and young, tame dogs and wild, are all alike, and that is m the interest they take in sport. The symptoms of preparation never fail to prod ace in them the most lively transports. The dog whose master is accidentally prevented from taking the field, will often seek out a neighboring sportsman, and enlist in his service for the day, though it would be a vain effort to entice him for any other object, and equally vain to attempt to retain him when the sport was at an end. Even in the company of his master, true as he is to his allegiance, he will attach himself for the occasion to a total stranger, who chances to be a better shot; and yet, far from deriving any advantage from the result, he entertains a dislike for the bones of game, which he eats, when he eats them at all, with the reluctant air that shows them to be distasteful.
