It is on this powerful agency that the steam-doctors rely, when, by moisture and heat, they stimulate all the innumerable perspiration-tubes and lymphatics to force out from the body a flood of unnaturally excited secretions; while it is "kill or cure," just as the chance may meet or oppose the demands of the case. It is the skin also that is the chief basis of medical treatment in the Water Cure, whose slow processes are as much safer as they are slower.

At the same time it is the ill-treatment or neglect of the skin which, probably, is the cause of disease and decay to an incredible extent. The various particulars in which this may be seen will now be pointed out. In the management and care of this wonderful and complex part of the body, many mistakes have been made.

The most common one is the misuse of the bath, especially since cold water cures have come into use. This mode of medical treatment originated with an ignorant peasant, amid a population where outdoor labor had strengthened nerves and muscles and imparted rugged powers to every part of the body. It was then introduced into England and America without due consideration or knowledge of the diseases habits, or real condition of patients, especially of women. The consequence was a mode of treatment too severe and exhausting; and many practices were spread abroad not warranted by true medical science.

But in spite of these mistakes and abuses, the treatment of the skin for disease by the use of cold water has become an accepted doctrine of the most learned medical practitioners. It is now held by all such that fevers can be detected in their distinctive features by the thermometer, and that all fevers can be reduced by cold baths and packing in the wet sheet, in the mode employed in all water-cures. Directions for using this method will be given in another place.

It has been supposed that large bath-tubs for immersing the whole person are indispensable to the proper cleaning of the skin. This is not so. A wet towel, applied every morning to the skin, followed by friction in pure air, is all that is absolutely needed; although a full bath is a great luxury. Access of air to every part of the skin when its perspiratory tubes are cleared and its blood-vessels are filled by friction is the best ordinary bath.

In early life, children should be washed all over, every night or morning, to remove impurities from the skin. But in this process, careful regard should be paid to the peculiar constitution of a child. Very nervous children sometimes revolt from cold water, and like a tepid bath. Others prefer a cold bath; and nature should be the guide. It must be remembered that the skin is the great organ of sensation, and in close connection with brain, spine, and nerve-centres: so that what a strong nervous system can bear with advantage is too powerful and exhausting for another. As age advances, or as disease debilitates the body, great care should be taken not to overtax the nervous system by sudden shocks, or to diminish its powers by withdrawing animal heat to excess. Persons lacking robustness should bathe or use friction in a warm room; and if very delicate, should expose only a portion of the body at once to cold air.

Johnson, a celebrated writer on agricultural chemistry, tells of an experiment by friction on the skin of pigs, whose skins are like that of the human race. He treated six of these animals with a curry-comb seven weeks, and left three other pigs untouched. The result was a gain of thirty-three pounds more of weight, with the use of five bushels less of food for those curried, than for the neglected ones. This result was owing to the fact that all the functions of the body were more perfectly performed when, by friction, the skin was kept free from filth and the blood in it exposed to the air. The same will be true of the human skin. A calculation has been made on this fact, by which it is estimated that a man, by proper care of his skin, would save over thirty-one dollars in food yearly, which is the interest on over five hundred dollars. If men will give as much care to their own skin, as they give to currying a horse, they will gain both health and wealth.

CLOTHING.

There is no duty of those persons having control of a family where principle and practice are more at variance than in regulating the dress of young girls, especially at the most important and critical period of life. It is a difficult duty for parents and teachers to contend with the power of fashion, which at this time of a young girl's life is frequently the ruling thought, and when to be out of the fashion, to be odd and not dress as all her companions do, is a mortification and grief that no argument or instructions can relieve. The mother is often so overborne that, in spite of her better wishes, the daughter adopts modes of dress alike ruinous to health and to beauty.
