ALTA.--For the bites and stings of midges, etc., rub a little dilute ammonia on the bite. This usually relieves the pain instantly. It is better to put a drop of dilute carbolic acid (about 1 in 100) upon the bite after using the ammonia. The reason for this is that the trouble from an insect's bite is dependent upon two causes. In the first place the insect actually drops poison into the bite. This, which is usually formic acid, makes the wound smart at once, but its effect passes off in a little time. Ammonia neutralises this acid and so gives instant relief. But there is a second cause of trouble which is far more serious. The bite of a fly has caused more deaths than you would think, and from this reason. Flies of all kinds are given to feed on garbage, and as they have not yet learnt to use a toothbrush, their mouths are always swarming with germs. Usually these germs are not of a very virulent kind. But suppose that a midge has been eating the carcase of an animal which has died from peritonitis. That fly is now more deadly than a viper, for on its tongue it has a poison which is capable of rapid increase if it ever finds a suitable home. If this fly bites you, you may die from the bite. Everyone knows that often an insect sting or bite does not ache or swell at first; but after several hours the place becomes hot and swollen, and if the place bitten be the hand, the arm begins to swell and the glands in the armpit enlarge. In this case a mild dose of microbes has been innoculated. Ammonia will not in most cases destroy these microbes. Therefore, we say, put a drop of dilute carbolic acid on the place as soon as you can. The ammonia simply relieves a little itching (for the poison of the insect itself is rarely dangerous), but the carbolic acid destroys organisms which are capable of great mischief. Rubbing the face and hands with oil of eucalyptus, or paraffin, will sometimes prevent insects from coming near you. LILY, MY QUEENIE.--1. Is the skin round your eyebrows scarred? Hair never grows on scars, nor can it be made to do so by any means in our power. If there are no scars, try a little white precipitate ointment applied carefully to the eyebrows.--2. Moles cannot be cured. They can be removed by operation. If they are large and noticeable it is better to have them removed. Otherwise leave them severely alone. PEARL.--Take our advice and see a doctor at once. Severe headache is a very common symptom, and though it is usually caused by some trivial ailment, it is often the only subjective sign of a serious disease. Your attacks suggest megraine, but they might be due to far more serious things. Without a complete personal examination no man living could diagnose your malady.
