An important function of the skin is to expel objectionable elements coming from the breaking down of the cells and from digestive processes; the skin is quite as important a factor in getting rid of this waste matter as those other processes more commonly considered in this connection. This action goes on most energetically when the secretion of perspiration is abundant and when the temperature of the surrounding air is so high that perspiration does not evaporate as rapidly as discharged. All these secretions contain more or less solid material which, unless removed, accumulates on the surface of the skin to clog up the glands and, in some cases, to putrefy and decay. It is this decay of organic matter on the surface of the skin which causes the odors plainly noticeable in a crowd, particularly in the winter time. This accumulation can be prevented only by frequent bathing and by wearing clean clothes, and there is no surer indication of a proper self-respect than the habit of cleanliness, both as to one's person and one's clothes. There is also the very practical feature that cleanliness is an effective method of discouraging infection and disease, partly by the removal of scurf and partly by the greater healthfulness of the skin thereby induced. Baths have always served as therapeutic agents, and evidences of their use may be found in Roman paintings and in Egyptian sculpture to-day. But from our standpoint it is their hygienic importance that is insisted upon. Ordinarily, the temperature of the bath should be between 90 and 100 degrees, and enough soap should be used to counteract the oily nature of the deposits on the skin. Unfortunately, facilities for bathing, except in summer, have not been generally supplied to detached houses in the country. Plumbing in most houses has been lacking, but in these days bath-rooms are being installed with surprising rapidity, and the conveniences resulting are enjoyed as soon as they are understood. Only a few days ago, the writer was told of a small village of perhaps two or three hundred persons where this last summer one house, the first in the village, was provided with a bath-room, to the great interest of all the villagers. The convenience and comfort involved were immediately appreciated, and the plumber, who came in from a neighboring city twenty miles away, secured contracts for and installed twelve bath-rooms in twelve houses before he was allowed to leave the village. This same interest is everywhere noticeable, and the lack of bathing throughout the winter, formerly, alas, so common, is now giving way to a greater cleanliness, thereby improving the health and character of the inhabitants.
