Thus treated, instead of the feeble and sickly appearance before mentioned, he will present a lively countenance, with all that activity of motion, and enjoyment of existence, which are natural to his age, and afford the surest criterion of vigorous health. Experience has fully convinced me of the great importance of attention to the lodging of children, as a prophylactic measure; and this renders me desirous of impressing upon the profession generally, the truth of my own convictions on the subject. With the same design of obviating the injurious effects of a high temperature upon the infantile system, I advise frequent ablutions with cool water, and its free employment as a beverage. Infants, unable to make their wants known, often suffer exceedingly from the inability of their attendants to understand them. During the heat of summer, the increased evaporation from their surface is necessarily productive of increased thirst, which, if unsatisfied, renders them uneasy and restless. To quiet them, the breast or bottle is offered. Aliment is thus given, where drink only was required; and the stomach, overloaded and oppressed, is apt to become irritable, and is thus brought into a condition most favourable to the occurrence of cholera. By attention to the peculiar language of infants, expressed not by words, but by signs, I have often been able to detect their wants; and, in many instances, have afforded the most decided relief, by simply giving them a little cool water for drink. From the dread which some individuals have for cool air and cold water, it would seem that they were considered rather as destructive poisons than as absolute necessaries. I have no fear of either, when judiciously employed; and as prophylactics in cholera, I do not think their place can be supplied.
