MA TANTE.--What is your work? This is the first question to ask anyone who is troubled with roughness of the arms. We would have been pleased if you had given us a description of the roughness of which you complain. Roughness above the elbows may be due to so many causes. If there is nothing to see upon your arm, no spots or patches, but simply a slight scaliness of the arm, wash the place in warm water and soap, and then smear on a very little lanoline or simple ointment. COMPLEXION.--1. We have published many long “Answers” on the subject of face-spots. In last year’s volume you will find a very long account of “acne” in an answer to “Fair Isabel.” In 1896 we published an article on face-spots. You should read these and they will tell you practically all that you require. The little article on the complexion, recently published, will also help you.--2. The soap that you mention is made for household and not for toilet use. We strongly dissuade you from using it for washing your face. TIGER.--We are always pleased to answer questions about the feet and hands, for the subject has great fascination for us. The cause and treatment of flat-foot are well understood; but it is far more easy to prevent the feet from becoming flat, than it is to restore the natural arch of the foot after it has once been broken down. The causes of flat-foot are numerous. Occupations which necessitate prolonged standing. How often we see flat-foot in policemen. Occupations in which you sit down all day. The office clerk is generally flat-footed. Weakness of the muscles of the legs, whether part of a general weakness or not, is another cause. Lastly, and vastly the most important cause of all is ill-fitting foot-gear. We do not believe that flat-foot would ever occur if people did not wear boots or shoes. If your boots are very well made, and do not bend at the waist, but are flexible in the toes, they will not produce flat-foot. But by far the greater number of boots bend in the waist only, the result is, that the centre of the foot, where nature intended that but little movement should take place, is the only part of the civilised foot which is free to bend. Its joints are dragged open at every step, the tendons and ligaments give way, the arch collapses and the foot becomes quite flat. To treat flat-foot, get boots which fit well, and which are prevented from bending in the centre by being stiffened with a steel waist. Pads are often used for this complaint. The pads are shaped like a division of an orange and are placed in the boots to support the instep. If they fit and are comfortable they are useful. If, as is usually the case, they do not fit, they cause extreme discomfort and do great harm. Walking on tip-toe for half an hour a day, without boots or shoes on, will help to strengthen the foot and relieve the flatness. Walking, running and jumping, are excellent exercises for the relief or flat-foot. Skipping is a pleasant and useful pastime for flat-footed
