AN EXCELLENT EYE-WASH.—I send you the following recipe, having found it very useful in my own case. It is especially adapted to relieve the pain and weakness incident to the eyes of elderly people, when depending on debility of the optic nerves:—Take sulphate of zinc, one drachm; spirit of camphor, three drachms; distilled water, hot, four ounces; rose-water, eight ounces. Pour the boiling water upon the zinc and camphorated spirit in a closed vessel, and when cold, strain through linen or fine tow; then add the rose-water.—J. WILSON, _Cork_. FOR WEAK EYES.—Two grains acetate of zinc, in two ounces of rose-water; filter the liquor carefully, and wash the eyes night and morning. I have used the above for many years.—M. A. S. GOULARD LOTION, OR LEAD WASH.—This may be made by dissolving one drachm of sugar of lead in a pint of soft water. Some persons are very fond of using this wash, with the addition of spirits of wine, as an evaporant; but I do not like it, for it renders the skin very dry and harsh, and its sedative virtue acting through unbroken skin, is not of much value. Under other circumstances, it is very often useful. When used as a wash for the eyes, two grains of the sugar of lead are to be dissolved in two table-spoonfuls of water. TO FILL A DECAYED TOOTH.—Procure a small piece of gutta-percha, drop it into boiling water, then, with the thumb and finger, take off as much as you suppose will fill up the tooth _nearly_ level, and while in the soft state press into the tooth; then hold on _that_ side of the mouth cold water two or three times, which will harden it.—The writer of this chanced to try it, and for two years has found it very successful; of course the breath is sweeter, and the tooth free from cold.—G. A. M. NEW METHOD OF FILLING TEETH.—Mix thirteen parts of pure finely powdered caustic lime with twelve parts of anhydrous phosphoric acid. This powder is moist during the mixing, and, while in that state, is to be introduced into the decayed tooth. The place in the tooth is to be made dry before receiving the mixture. This kind of filling must be used two or three minutes after being prepared. Soon after it is lodged in the decayed cavity, it becomes very solid.—E. A. C. SIMPLE MEANS OF REMOVING TARTAR FROM THE TEETH.—In the summer months, tartar may be effectually removed from the teeth, by partaking frequently of strawberries. TOOTH-POWDER.—Powdered orris-root, half an ounce; powdered charcoal, two ounces; powdered Peruvian bark, one ounce; prepared chalk, half an ounce; oil of bergamot or lavender, twenty drops. These ingredients must be well worked up in a mortar, until thoroughly incorporated. This celebrated tooth-powder possesses three essential virtues, giving an odorous breath, cleansing and purifying the gums, and preserving the enamel; the last rarely found in popular tooth-powders.—C.
