23. In that form of _Ophthalmia_ commonly known in India by the name of _Country Sore Eyes_, especially when it attacks children, a solution of Alum is often of great service. For children the strength of three grains to an ounce of water is sufficient; but for adults, a solution of double this strength may be used: the eyes should be freely washed with it four or five times a day, or a cloth wet with it may be kept constantly applied. If the eyelids are much swollen, especially in the morning, they should be well bathed with warm milk, the eyelids should then be carefully separated, and the Alum lotion dropped in. There is a native plan of treatment of these cases which proves in many instances effectual, but it has the disadvantage of being very painful for a short time. It is as follows: Place some finely powdered alum on a heated plate of iron, and whilst it is in a state of fusion add a small portion of lemon or lime-juice, until it forms a black, soft mass. This, whilst hot, is applied entirely round the orbit, care being taken that none of it gets beneath the eyelids, as it causes under such circumstances intense agony. One or two applications, each being allowed to remain on for twelve hours, suffice ordinarily to effect a cure. 24. _After severe Blows on the Eye_, when the pain and heat have subsided, and much discoloration and swelling remain, an ALUM POULTICE is an effectual application. It is made by rubbing up 30 grains of powdered alum with the white of an egg till it forms a coagulum. This placed between two pieces of thin rag or muslin, should be kept applied to the eye for some hours. 25. _In Hæmorrhage from the Lungs, Stomach, Kidneys, Uterus, and other Internal Organs_, Alum, in doses of 10 to 12 grains, thrice daily, with or without opium, may often be given with advantage. It is, however, inadmissible if much fever is present, and should at once be discontinued if after the first few doses the symptoms are at all aggravated. The following, called ALUM WHEY, is a good form of administration: Boil for ten minutes two drachms of powdered Alum in a pint of milk, and strain; of this, the dose is one and a half to two ounces thrice daily. This may also be given with the view of checking _Excessive Menstrual Discharges_ (_Menorrhagia_) and _Bleeding from Piles_. In this last case, clothes saturated with a solution of Alum in decoction of Galls (145) or Babúl bark (9), in the proportion of two drachms to eight ounces, should be kept constantly applied externally. This application also proves useful in _Prolapsus (descent) of the Anus_, especially in children. _In Profuse Bleeding from the Nose_ injections of a solution of Alum (20 grains to one ounce of water) into the nostril is sometimes effectual; care, however, is required in its use. Powdered Alum, or a very strong saturated solution, applied locally on a compress, occasionally suffices to arrest _Bleeding from Leech-bites, Cuts, &c._
