As we have before mentioned incidentally, the proper ventilation of the bathroom is a matter of prime importance; for since the respiration is quickened by the act of bathing, it is evident that a foul atmosphere in the bathroom is very liable to produce an ill-effect upon the bather. Many of the swimming baths in London are very defective in this respect, and we have been forcibly struck, in more than one of them, by the ammoniacal odour proceeding from those sanitary offices which are a necessary adjunct to every bathing establishment. It is a very common custom in private houses to place the bath and the water-closet in the same apartment. That this is an undesirable arrangement is evident, for the water-closet is, of all places in a house, that in which a foul atmosphere is most likely to be encountered. Although a bathroom should be well ventilated, it should certainly not be draughty, for currents of cold air blowing upon the moist skin of the bather are likely to give “cold,” and produce internal congestions of various kinds. In summer there is no difficulty in providing a sufficiency of fresh air, but in winter it is not so easy. The best way, perhaps, to provide for a constant renewal of air is to admit air by means of vertical tubes, and to have in the room an open fireplace, in which a brisk fire should be burning while the bath is being administered. In order to ensure a proper reaction after a cold bath, and to prevent chill after a hot one, it is customary to provide the bather with a supply of hot linen. This is a great comfort and a luxury, and may even be looked upon as an absolute necessity for delicate persons. It is a very general custom on the Continent for the bather, after removing the greater part of the moisture from his body, to don a hot calico Peignoir, or bathing-gown, which protects from chill, and at the same time allows of the limbs being rubbed with towels. It is not necessary to say much about towels. They are to be got of all qualities, from those as soft as a cambric handkerchief to those which, in roughness, approach the qualities of a curricomb. The bather may please himself in this matter, and will choose a soft absorbent towel to remove the moisture, and a hard one to rub the surface and produce the necessary reaction. Horsehair gloves and various rubbers made of indiarubber, &c., are in use, and require only to be mentioned.
