Priessnitz considers these complaints wholesome, being the medium chosen by Nature for relieving the system. On their appearance, his great aim is to strengthen the patient, and eliminate the morbific matters by the pores of the skin. It is frequently asked, "But does not the hydropathic process drive the virus into the system?" No, on the contrary, the packing-sheet acts as a poultice to the whole body; and this, followed by a tepid bath, causes an outward action, and the system is cooled and relieved through miles of drainage (the pores), the true medium through which relief can with certainty be obtained. A young man with measles, at Gräfenberg, had as many as 400 packing-sheets applied in about fourteen days. _Small-Pox._--Small-pox, of all diseases, is that which should be treated hydropathically; because by its operation the morbid matters are thrown out by the pores of the skin, upon which it rarely leaves any of those scars so detrimental to the beauty of the person. In the Water-cure, judiciously treated, the small-pox is under no circumstances attended with danger, nor is the patient reduced in strength as under any other treatment. "Small pox," Priessnitz says, "instead of being suppressed, ought to be encouraged, as it relieves the system of humours that ought to be carried out of it, and is a healthy process." At one period the profession were as much at fault in the treatment of small-pox, as they now are in that of cholera. No means were left untried, but they failed in arresting its ravages. Jenner's discovery was hailed as an intervention of Providence, and he was voted two grants in parliament. If Priessnitz is right, this discovery may be hailed as a curse rather than a blessing. He states that the insertion of poisonous matter into the blood of a healthy subject produces poisonous consequences, is repugnant to our feelings, and at variance with the laws of nature. In small pox, where there is much eruption on the face, a muslin handkerchief, wetted, may be used as a bandage to the part. If the head is much affected, head-bath and wet bandages must be resorted to. Bandage the back and thighs if they require it. In these complaints, as in all others, if the bowels require opening, use injections. Drink plentifully of water. I treated a young lady in small-pox as follows:--
