Is a very painful and well-known complaint, arising sometimes from cold, and frequently from a very acrid blood which stimulates the delicate vessels of the eye, swelling and inflaming them. The following eye waters are very good to cool sharp, hot humours, they may be readily prepared, and will more effectually answer their end if assisted by the use of diuretics at the same time. First, calaminaris levigated, half a dram, rose water, 2 oz.—Second, take white vitrol, 15 grains, rose water, 2 oz.—With either of these, the eyes may be washed at discretion, in all hot defluctions; but when the sight decays from dryness, or a defect in the optic nerve, such things can avail but little.—When a poultice is necessary, you may take half a pint of the decoction of linseed, and as much flour of linseed as is sufficient to make it a proper consistency. This poultice is preferable to bread and milk for sore eyes, it will not grow sour nor acid. In corroboration of the above, we give a letter to the editor of the Mechanics’ Magazine, page 95, vol. I. “Sir,—Reading your miscellany to a friend, a cure for weak eyes, he had recourse to your receipt, and was cured in a short time, though he had previously spent much money without getting relief from the faculty. I hope your readers who may be in a similar situation, will follow the example.” OINTMENT FOR BURNS. This ointment has never yet failed to give relief; yellow basilicon 3 ounces turpentine 1½ ounce. FOR SHORTNESS OF BREATH. Mix ¾ of an oz. of fine powdered senna, ½ an oz. of the flour of brimstone, ¼ of an oz. of powdered ginger, in 4 oz. of clarified honey. Take about the size of a nutmeg every night and morning for five successive days, afterwards, once a week for some time, and finally once a fortnight. TO MAKE GINGER BEER. One ounce and a half of well-bruised ginger, 1 ounce of cream of tartar, 1 sliced lemon, 1 pound of white sugar. Put these ingredients into an earthen vessel, and pour upon them a gallon of water, boiling; when cold, add a table spoonful of yeast, and let the whole stand till next morning; then skim and bottle it; keep it three days in a cool place it will then be fit for use. PROBLEMS. A country woman carrying eggs to a garrison, where she had three guards to pass, sold at the first half the number she had, and half an egg more; at the second, the half of what remained, and half an egg more; and at the third, the half of the remainder and half an egg more; when she arrived at the market-place, she had three dozen still to sell, how was this possible, without breaking any of the eggs?
