"It is generally the weak and debilitated who are the most sensual and debauched." "The sound man has purer tastes, independent of his greater self-command." "We find amongst the children of nature, amongst simple peasants who have had but little contact with civilisation, the purest virtue and truest feelings of honor."--PRIESSNITZ. OBSERVATIONS.--Persons who consider themselves in health, will derive advantage by six weeks' or two months' treatment at Gräfenberg, and will learn how to apply it to themselves or families. Parents will there acquire the habit of using cold water, be prepared to ward off disease from themselves, and learn, by simple means, how to preserve the health of their children. Officers in the army, who have an insight into hydropathy, will have nothing to fear from epidemics; they will find that fevers and inflammations are diseases which form the easiest part of Mr. Priessnitz' practice. The water at Gräfenberg has no advantage over that which we find everywhere, except that it is peculiarly cold and fresh. In the general purposes of the cure, water should be soft, that is to say, it must possess the quality of dissolving, and for this reason it must be cold, and divested of all mineral properties; for to prove its fitness, linen cloth washed in it must become white, and vegetables dressed in it tender. Trout living in water does not prove its softness, but frogs do; the softest of all waters is the rain. Hard water makes the skin rough, but soft water, on the contrary, renders it smooth. When water, with the slightest acidity in it, has been suffered to remain in leaden pipes, pumps or cisterns for any length of time, it absorbs the dangerous qualities of the lead; and this has been known to produce serious consequences. It is necessary, therefore, that water should be drawn off before any is drunk. Those who wish to begin ablutions in winter, should do so in a warm room, and as a beginning, instead of washing, they may wet a towel, and with it be well rubbed all over twice a day, or use the rubbing-sheet. The morning immediately on getting out of bed, is the best time for the first ablution; the other should be undertaken two or three hours after eating, _never_ on a full stomach, nor immediately after making any great exertion. The rubbing should be continued from three to five minutes. It is conceived that one ablution a-day, and the drinking of cold water, will enable those who are in health, and in the enjoyment of life, to continue in that state. After any excess, instead of resorting to drugs, the rubbing sheet should be resorted to, and an increase in cold water as a beverage. The same means may be resorted to by persons who have any reason to suppose that they have caught cold.
