A partial warm bath, such as the foot-bath, is of much service in warding off many complaints. If a child get the feet wet, plunging them into warm water will often prevent any ill consequences; and even when the first chill and slight shiverings which usher in colds, fevers, and other inflammatory complaints, have been complained of, the disease may be cut short by the use of a foot-bath, continued till free perspiration occurs. RULES FOR THE USE OF THE WARM BATH. TEMPERATURE OF THE WATER.--When the warm bath is used as a measure of hygeiene, as a general rule, any degree of temperature may be chosen between 92 degrees and 98 degrees, which appears to be most agreeable to the child; but on no account must 98 degrees be exceeded. When ordered as a remedial measure, the temperature will of course be fixed by the medical attendant. The same degree of temperature must be kept up during the whole period of immersion. For this purpose the thermometer must be kept in the bath, and additions of warm water made as the temperature is found to decrease. These additions of warm water, however, must be regulated by the indications of the thermometer, and not by the feelings of the child. PERIOD OF REMAINING IN THE BATH.--This must depend upon circumstances. As a measure of hygeiene, it must be varied according to the age of the child. For the first four or five weeks, the infant should not be kept in beyond three or four minutes; and the duration must afterwards be gradually prolonged as the child advances in age, until it extends to a quarter of an hour, a period which may be allowed after it has attained the age of four years. When the bath is employed as a remedial agent, the time of immersion must be prolonged; this will be determined by the medical adviser. Speaking generally, a quarter of an hour may be said to be the shortest period, an hour the longest, and half an hour the medium. When in the bath, care must be taken that the child's body is immersed up to the shoulders or neck, otherwise that part of the body which is out of the bath (the shoulders, arms, and chest), being exposed to the cooler temperature of the air, will be chilled. When the infant or child is taken out of the bath, the general surface, especially the feet, must be carefully rubbed dry with towels previously warmed; and when one of the objects of the bath is to excite much perspiration, the child should be immediately wrapped in flannel and put to bed. When, however, the object is not to excite perspiration, the child may be dressed in his ordinary clothing, but should not be allowed to expose himself to the open air for at least an hour.
