Under this title I shall only take notice of domestic baths, which are made in bathing tubs fitted for that purpose. The water made use of must be soft and light, lathering readily with soap. If this is not to be had, it must softned by the addition of soap, or by mixing it with milk, or by boiling wheat bran in it. Likewise it may be corrected by camomile flower, or the leaves, flowers or roots of white lilies, or lastly the leaves of mallows or marsh-mallows. The water should be made pretty warm, but not too hot, for then it will have bad effects. A bath thus made is useful to promote an easy delivery, especially if it be the first child, and the woman is not young and of a dry constitution; but it must be used principally in the last months. Likewise in the dorsal consumption of infants, and in the rickets; because they open the obstructed and constricted vessels, render the nutritious juice more fluid, and more easy to be distributed all over the body. But the cold bath is the best in this last cafe, if the child is immediately put between blankets, to sweat after it.
These sort of baths are good in diseases of the head, in melancholy, in disorders of the mind, attended with dreadful dreams, the head-ach, giddiness of the head, tooth-ach, and other pains of the nervous parts; particularly the pains of the stomach, the colic, and a fit of the gravel. They are so remarkable for easing pains arising from spastic strictures, that though some are quite at ease while they fit in the bath, they will return as soon as they are out of it. They like-wise promote the circulation of the blood and humours, and forward perspiration through the skin; for if the patient removes from the bath into a warm bed, and his body is rubbed with dry cloths, he will fall into a profuse sweat.
