PEGGIE.—It is very common for persons, especially children, to grind their teeth during sleep. There are many things which can account for the habit. Errors of diet are the chief of these. Late, or large suppers are very potent causes. Another cause is irritation about the face or head. The presence of bad teeth, of enlarged tonsils, or adenoids, or of anything hindering free respiration through the nose are also very apt to cause tooth grinding during sleep. The treatment for it is to breathe through your nose, or if you cannot do so now, have your nose seen to so as to enable you to breathe properly, and avoid late suppers. You should also be careful not to sleep upon your back. A. M. O. L.—Yes; sulphur soap and sulphur ointment used as we advised “Fair Isabel” to use them in last year’s volume, page 448. Whatever you do, be very careful of the soap you use for your face. DILLY.—You are quite right in persevering in the treatment of acne. What troubles you now is really a very simple matter. The sulphur kills the outer layer of the skin and that causes the flaking and cracking of the skin which annoys you. Now what you should do is to leave off the ointment for a fortnight or more and see how you get on. If the acne gets worse, then return to the sulphur ointment, only use it diluted with an equal quantity of lanoline or vaseline. Your face will soon get right again. Wear a veil when you go out, and apply a little glycerine and rose water (a dram of glycerine to an ounce of rose water). ALMA.—Do not let your daughter grow up with a hare-lip. This hideous deformity is readily cured by a small operation. Nothing is left of it but a small scar to mark the site of the operation. The earlier the operation is done the more excellent will be the result. BELLE.—Undoubtedly the use of tight corsets is a very fertile cause of indigestion. And, indeed, it is a potent factor of that terrible form of indigestion associated with ulceration of the stomach. Some of the greatest medical authorities aver that the reason why that most serious disease is so far more common in women than in men, is because the former wear corsets. Be this as it may, it is an absolute fact that it is quite impossible to cure indigestion if the sufferer wears tight corsets. There is no necessity to abandon corsets altogether, but you must wear them loose. And why should you not wear them loose? It is no longer fashionable to have a waist like a wasp!
