O MIMOSA SAN.--Certainly all your symptoms can be traced to your bad teeth. You complain of flatulency, headache, constipation, cold feet, and poor appetite. Are not all these common symptoms of dyspepsia? And what is commoner as a cause of dyspepsia than bad teeth? Go to the dentist again and have your teeth thoroughly overhauled. But remember, if you have many teeth extracted, you _must_ have false ones inserted in their place. Have the false teeth made at once, for after a month or two the remaining teeth make an attempt to fill up the gap where bad teeth have been extracted and leave your teeth with narrow slits between them. How few people recognise the value of teeth! Normal digestion is quite impossible without them. AN IRISH READER.--1. Do you wear a straw hat, and do the spots on your forehead correspond to the line where the hat presses? During the summer many girls develop spots on their foreheads from the irritation of straw hats. These spots often trouble girls, who seek in vain for their cause. The real cause scarcely ever presents itself to their notice. If you have thoroughly tried sulphur ointment without success, use ichthiol ointment 2½ per cent. instead. Also see that your hats do not press upon your forehead.--2. The fifth of September, 1877, was a Wednesday. LORNA DOONE.--One would naturally suppose that such a simple subject as the care of the nails was completely understood. But this is, nevertheless, far from being the case, and it often gives more trouble to cure thin or broken nails than it does to cure some of the most deadly diseases to which we are subject. We advise your friend to soak her finger-tips every night in hot water and then to smear them with lanoline or other simple ointment. In the morning she should wipe off the ointment and dip her fingers into pure alcohol for five minutes. She should also be very careful to cut and trim her nails properly. We do not promise to cure her, but we have seen good results from this treatment. MAORI.--The hair frequently falls off in larger quantities in autumn than in any other season. Indeed, it appears that the hair of man “moults” as does the fur of mammals and the feathers of birds. After autumn, the spring is the time of year at which the hair falls out in greatest quantities. This periodical moulting of the hair does good rather than harm, and there is really no call to stop it--if, indeed, it could be stopped, which we question. AGRICOLA.--“What is the difference between a sprained and a varicose vein?” We really do not know what you mean by a “sprained vein,” so that part of the question we cannot answer. Systematic rubbing or massage is of some value for varicose veins; but it is not altogether safe, and is not worth a trial. Rest with the legs elevated, walking, and the support given by an elastic stocking are the chief items in the treatment of varicose veins. Standing is to be avoided as far as possible.
