MARY NOBLE.--Undoubtedly you do suffer from chronic nasal catarrh. It is the rule for persons afflicted with this malady to be subject to constantly recurring attacks of acute inflammation of the nose. You must get the following powder made up and use it three or more times a day:--Chlorate of potash, bicarbonate of soda and borax, of each, one part; powdered white sugar, two parts. Dissolve one teaspoonful of the powder in half a tumbler of tepid water, and use it as a nose wash and gargle. Wash out your nose thoroughly with this lotion, and then apply the following paint with an "atomiser" or nasal spray--menthol in paroleine, sixty grains to the ounce. FLUFF.--Wash your head in borax and water once a week, and then rub a little sulphur ointment into the roots of the hair. It is quite impossible for us to answer any correspondent in less than six weeks' time from receiving her letter. Often, at this time of the year, it is two or three months before a letter can be answered. A READER.--See answer to "Fluff" for scurf on the head. Scurf on the face is usually secondary to that on the head. Apply sulphur ointment, made with lanoline, for a week or so. Be careful of the soap you use. THROAT.--Catarrh of the throat is of course at the bottom of your trouble, and if we can cure this, we will probably at the same time improve your hearing. You should treat your throat in the same way that we advised "Mary Noble" to do. The great secret of success is to thoroughly and completely wash out the nose and throat while you are about it. We would advise you to syringe out your left ear to make certain that there is no wax there. ST. CECILIA.--The reason why you so frequently suffer from "colds" is most probably because you are the subject of chronic nasal catarrh. Read the answer to "Mary Noble" above, and do the same as we advised her to do. SYLVIA.--Inhalations of steam impregnated with medicinal substances are exceedingly useful, especially in bronchitis or catarrh of the throat. If you have an inhaler handy so much the better; if not, you can make an excellent inhaler out of a jug. Fill the jug or inhaler with hot water, add the drugs prescribed (most probably, compound tincture of benzoin or camphor), place your face over the jug, being careful not to scald yourself, and cover your head with a large dry towel, shrouding yourself with the jug beneath its folds. Inhale for about half an hour or less. Be very careful to keep out of draughts after inhaling. Very severe colds, if nothing worse, may occur from carelessness in this respect.
