Not while he is perspiring _violently_, or the perspiration might be checked suddenly, and ill consequences would ensue; _nor ought he to be put in his tub when he is cold_, or his blood would be chilled, and would be sent from the skin to some internal vital part, and thus would be likely to light up inflammation—probably of the lungs. His skin, when he is placed in his bath, ought to be moderately and comfortably warm; neither too hot nor too cold. 122. _When the child is a year old, do you recommend cold or warm water to be used?_ If it be winter, a little warm water ought to be added, so as to raise the temperature to that of new milk. As the summer advances, less and less warm water is required, so that, at length, none is needed. 123. _If a child be delicate, do you recommend anything to be added to the water which may tend to brace and strengthen him?_ Either a handful of table salt or half a handful of bay salt should be previously dissolved in a quart jug of _cold_ water; then, just before taking the child out of his morning bath, let the above be poured over and down the back and loins of the child—holding the jug, while pouring its contents on the back, twelve inches from the child, in order that it might act as a kind of douche bath. 124. _Do you recommend the child, after he has been dried with the towel, to be rubbed with the hand?_ I do; as friction encourages the cutaneous circulation, and causes the skin to perform its functions properly, thus preventing the perspiration (which is one of the impurities of the body) from being sent inwardly either to the lungs or to other parts. The back, the chest, the bowels, and the limbs are the parts that ought to be well rubbed. CLOTHING. 125. _Have you any remarks to make on the clothing of a child?_ Children—boys and girls—especially if they be delicate, ought always to wear high dresses up to their necks. The exposure of the upper part of the chest (if the child be weakly) is dangerous. It is in the _upper_ part of the lungs, in the region of the collar-bones, that consumption first shows itself. The clothing of a child, more especially about the chest, should be large and full in every part, and be free from tight strings, so that the circulation of the blood may not be impeded, and that there may be plenty of room for the full development of the rapidly growing body. His frock or tunic ought to be of woolen material—warm, light, and porous, in order that the perspiration may rapidly evaporate. The practice of some mothers in allowing their children to wear tight bands round their waists, and tight clothes, is truly reprehensible.
