and sores, swarming with vermin, and starving with hunger. Verily, no one, until they have seen "the city of the Faithful," can understand in its full force, "I have not the life of a dog!"

A newfoundland dog, which, as is common with dogs, took great pleasure in walking with his master; he soon found out that the act of taking hat and gloves, or of merely putting aside books and papers, at certain times of the day, were indications of the master's intention of going out, and he expressed his anticipation of pleasure by manifest signs. Several times, however, the dog had been sent home, as his company could not always be convenient to his master. The consequence was, that the dog would take good care not to show that he expected to leave the house, but he would slily steal out of the room as soon as he thought that any indications of a walk had been given, and wait at a certain corner, which the master had to pass daily, and which was at a considerable distance from home. Surely this indicates some operation of the mind not to be accounted for by instinct.

I can give another more striking instance of mental operation in this intelligent animal: he accompanied a servant who rode to a place some distance from home. The horse was tied to a tree in front of a house while the servant executed his message. When, after some delay, he came out of the house, the horse was gone; he went on a hill, and from this elevated spot he observed the dog leading the horse by the bridle, which the canine leader held in his mouth, both trotting at a moderate pace. The dog brought home the horse and led it to its proper place in the stable. So he was in the habit of leading one of the horses to be watered. This animal was sent from the coast of Labrador, and was not of the common long

haired breed of Newfoundland dogs.-Lieber's Political Ethics.

There is a chapter in one of our metaphysical writers, showing how dogs make syllogisms. The illustration is decisive. A dog loses sight of his master, and follows him by scent till the road branches into three; he smells at the first, and at the second; and then, without smelling further, gallops along the third. That animals should be found to possess in perfection every faculty which is necessary to their well-being is nothing wonderful; the wonder would be if they did not; but they sometimes display a reach of intellect beyond this. For instance, dogs have a sense of time so as to count the days of the week. My grandfather had one who trudged two miles every Saturday to market to cater for himself in the shambles. I know another more extraordinary and well-authenticated example

A dog, which had been sold by an Irishman, and was sold by him in England, would never touch a morsel of food on a Friday; the Irishman had made him as good a Roman Catholic as he was himself. The dog never forsook the sick-bed of his last master, and when he was dead, refused to eat, and died also.

An Intelligent Dog.-A person of the name of John James, residing at Little Eccleston Hall, near Poultonle-Fylde, a few days ago went on his ordinary business to Lancaster, accompanied by a shepherd's dog kept by him. After his arrival, he had occasion to write to his family at home. He accordingly indicted a letter, and gave it to the dog, desiring him to go his way back, and carry it safe;" which the dog did, performing his master's wish in three hours. The distance was twenty miles.

A Religious Dog.-Mr. Simpson, farmer at Bowness,

in Cumberland, has at present a sheep-dog in his possession which attends church every sabbath during the morning service. As soon as the bell commences ringing, the dog shows symptoms of considerable anxiety; and after a few peals have been rung, he may be seen proceeding towards the sacred edifice, unaccompanied by any one. Perhaps the most extraordinary fact is, that he never attends the church but on Sundays, although the bells ring frequently during the week.

A Word for the Dumb Creation.-During sultry weather, all persons who keep dogs and horses, will, if they be thoughtful and humane, give them free access to water, and plenty of it. The annual English epidemic, a horror of mad dogs and hydrophobia, when at its full height, causes magistrates even to issue ordinances for the destruction of all dogs found at large. It would be much more to the purpose if they provided fountains at which the poor creatures could quench their thirst. In Portugal, and other hot countries, where dogs are much more numerous than here, and many of them ownerless, the disease called hydrophobia is unknown, because there they have the liberty of assuaging the intensity of thirst at their option, which is the great preventative against this fatal malady.

MATERIA MEDICA.

BLISTER.

ARE applications to the skin, which separate the cuticle in the form of vesicles containing a serous fluid. They excite increased action in the vessels of the skin, by means of which this fluid is thrown out. The part or neighbouring parts are somewhat relieved by this discharge, but more by the inflam mation and pain which are produced, and which lessen the inflammation and pain previously existing in some contiguous part.

The substances used are various; the most important is the meloe cantharides or Spanish fly. Euphorbium is sometimes used. In common blistering for strains, &c., where the expense of cantharides is objected to, auxiliary vesicatories may be admitted, among which the tincture of croton is now used.

Melt the three latter articles slowly together, and when not too hot, gradually mix the cantharides or flies.
