BUTTERCUP.—The condition of your head is known as “alopecia areata.” We do not think that it was caused by your wearing a comb; but as the disease is exceedingly obscure, we have no alternative cause to suggest. The best thing to do for it is to paint the place with tincture of iodine every day till it becomes slightly sore. Another way of treating it is to use white precipitate ointment. How much good is done by treatment we cannot say; we have never yet seen a case in which the hair did not grow again, whether the condition had been treated or not. Sometimes the patches remain bald for a considerable time; at other times hair begins to grow again in a week or so. LIZZIE.—The best way to treat warts is the following. Wash your hand well with soap and water, and then let the hand soak in hot water for two or three minutes so as to soften the wart; wipe your hand quite dry, and apply a little vaseline round the wart. You must not let the vaseline get on the wart. It is painted on the skin to prevent the caustics applied to the wart from injuring the adjacent skin. Now drop one drop of glacial acetic acid on to the wart; leave it one minute, and then rub the wart thoroughly with a stick of lunar caustic. This treatment may need to be repeated, but it rarely fails if properly done. Solvine is also of value in removing warts. Warts are frequently due to irritation of the skin, and are undoubtedly locally infective. MORELLA.—It is easy enough to account for boils recurring. It is by no means uncommon to hear this sort of account, “Six months ago I had a boil; it went away after a time, but another one developed shortly afterwards. This in its turn went away, and another came, and in this manner I have had twenty boils in succession.” In days when nobody knew anything about the diseases of the skin, this was explained thus—“The blood is in a bad state, and the matter in the boil is the impurity of the blood finding its way out.” This, we now know, is incorrect. The proper explanation is this—the first boil resulted from the inoculation of microbes into a hair follicle or sweat gland. These germs increased, poisoned the part, and produced the pus by their irritation. The boil was untreated, it burst and set free these organisms, which at once started to find a new home in a fresh follicle or gland. Had the boil been properly treated at first by destroying the microbes, the trouble would then and there have ceased. Boils are not dependent upon bad blood, nor are they influenced by internal treatment or dieting. They can be completely cured by applying hot fomentation wrung out in solution of carbolic acid (1 in 40). Poultices should never be applied to boils.
