The lukewarm daily bath, taken either in the morning or evening, ought to be continued until at least the age of four years. If, after the fourth or fifth year, ablutions of the entire body be resorted to only every second or third day, the practice should be commenced of sponging the chest every morning with cold, or alternately with cold and hot water, followed by brisk frictions. Soap is to be used but sparingly in the bath of young children. It must be of the blandest and purest quality. Various eruptions are caused by the employment of impure soaps, and even by the excessive application of the best kind. In illustration of the importance of our present subject, we may state that Dr. Hufeland, to whose admirable work on the art of prolonging life we have before alluded, lays down, as one of the means which lengthen life, the care of the skin. He dwells upon the benefit of paying such attention to it from infancy that it may be kept in a lively, active, and useful condition. The power of the bath to ward off disease in childhood is not sufficiently appreciated by parents. Properly managed, it soothes, but never increases, any internal irritation which may exist, and often does away with the necessity of resorting to the administration of drugs. If due attention were paid to the condition of the skin in early life, many of the most common ailments of childhood would be averted. The daily employment of the bath, and scrupulous attention to cleanliness of the person and clothing, would materially lessen the demand both for purgative medicines and for soothing syrups. One word more in regard to the washing of the infant. The mother herself, if she be in health, should always perform this office, and not entrust it to the child's nurse. Plutarch awards high praise to Cato the censor, for his invariable custom of being present when his child was washed. Every mother, at least, would do well to follow the example of this old Roman. It will give her the opportunity to detect many incipient affections which would for a long while escape her attention if she saw the child only when dressed. The mother will also take pains to engage the mind of the little one, and render the bath a source of amusement to it. After the fourth or fifth year, two or three baths a week during the colder seasons of the year will be sufficient to keep the skin clean, and properly active. During the summer, however, a daily bath is of great advantage to children, and ought not to be neglected. Swimming is very useful and very invigorating to the health of both sexes. It is desirable that children be taught this art.
