_Treatment of the Feet._—All the plans for prevention are curative. Chilblain in the feet often assumes a more serious form than in the hands, and the application of _cold_ water is inadmissible, especially in the case of females. The three degrees of chilblain in the feet are: 1st. The skin is red in patches, and slightly swelled, with more or less itching or tingling, with slight tenderness. 2d. Small blisters appear, surrounded by a livid skin. 3d. Ulceration and mortification take place. For the first two cases, which are most common, the frequent application of tepid water (using plenty of soap) gives relief. A leech is a useful remedy to unload the overcharged blood-vessels; or the part may be pricked with a needle, or punctured with a lancet; in such cases a soft bread-and-water poultice should be kept on during the night, applied warm, so as to encourage the flow of blood. LEECHES. Common as leeches are now, few persons have any notion of the distance from which they are brought for our use. Our own country furnishes at present few, if any, medicinal leeches. Formerly they were imported from France, but now, many are brought from Syria, and, as they are very delicate creatures, vast numbers of them are often lost in a rough passage across the sea. Leeches should be kept in a cool place, in a stone or glass jar, filled with river water, and tied over with coarse muslin to prevent their escape, though it allows them air. The water should be changed only when it begins to get foul, as too frequent disturbing destroys them. They are also sometimes found dead after storms. There is often a great deal of trouble in getting leeches to fix. The part on which they are to be applied should be carefully cleared of perspiration, and wiped with a cool moist cloth, so as to leave it damp. If they do not take readily, the part may be moistened with a little sugar and water, or milk. But if this does not answer, the skin may be gently scratched with a needle-point, till the blood comes, and then they will take. If it be wished to put the leeches as near as possible on one spot, the best plan is to put them all in the deep part of a small pill-box, or in a small wine-glass, which is to be turned down on the part. If you wish them to spread over a large surface, as upon one of the limbs, or the stomach, they must be put on singly and by hand, which is often very tedious and tiresome work. They should then be held tightly by the tail, wrapped in a piece of wet rag, so that they may be less inconvenienced by the heat of the hand; and if the leech do not soon fix, it is best to put it again into the water to cool itself, and after applying others, to try it again. It is always best to have more leeches than the number directed, in case some will not bite.
