HYDROPHOBIA.—No kennel should be without this medicine:—Six ounces filings of pewter, six ounces rue, four ounces garlic, four ounces mithridate or Venice treacle. Cut the rue and garlic small; mix them with three quarts of strong beer, or white wine, in an earthen vessel that can be stopped close; put it into a pot of water with hay tied about it, to prevent it from being broken against the sides of the pot when the water is boiling; let it simmer over a slow fire three or four hours, then squeeze the liquor from the herbs, bottle it for use, and seal the cork. How to apply it:—For a dog, one table-spoonful the first day, two the second, three the third, four the fourth, and five the fifth; continue to give five for four mornings more; nine mornings in all. The same quantity to man or woman, making allowances for robust or less vigorous frames. To a child, half the quantity. POISON.—When you have reason to suppose that you have accidentally swallowed a poisonous substance, and proper medical advice is not at hand, take an emetic. This may be done almost instantaneously by swallowing a cupful of warm water mixed with a tea-spoonful of mustard. If you have not dry mustard in the house, you are almost sure to have a mustard-pot, and a quantity from that put into the water will very quickly empty the stomach. As mustard may thus prove of so much use, it should never be wanting in any house; but even should there be no mustard at hand, warm water by itself forms a tolerably efficacious emetic. A HINT TO INVALIDS.—It may not be generally known to persons in delicate health that new milk put into a vessel, and let stand until it becomes of a pleasant sourish taste, is much more wholesome and nutritious than sweet milk; it is more cooling and strengthening, and agrees with many stomachs with which new milk will not.—H. C. A FUMIGATION FOR INFECTED AIR.—Take muriatic acid, and nitrous acid, of each half an ounce; put them into a quart bottle; add of manganese an ounce and a half; carry this about the room for a few minutes; a powerful smell will then be perceived, which will be sufficient; then let the bottle be closely stopped till the air begins to be offensive, when the same method must be repeated. This will last for months. TO PREVENT INFECTION FROM TYPHUS FEVER.—Six drachms of powdered saltpetre, six ounces oil of vitriol; mix them in a tea-cup by adding one drachm of the oil at a time. The cup to be placed during the preparation on the hearth, and to be stirred with a tobacco-pipe. The cup to be placed in different parts of the room.—F. E. W. TO REMOVE THE SMELL OF HOUSE SEWAGE.—Mix gypsum (sulphate of lime), with the sewage, which is called “deodorising,” and it will partially answer the purpose; but peat charcoal will be found a more effective addition. TO CURE THE STING OF A WASP.—Apply oil of tartar, or solution of potash, to the part affected, and it will give you instant ease.—F. E. W.
