In typhus fever, medical men do not make the distinction between congestion of the venous and arterial systems. They imagine that inflammatory action exists, whereas it is in typhus, venous congestion: therefore, the leeching and severe depletory measures are decidedly wrong; they increase the existing evil, lower and exhaust the vital powers, and if persevered in, lead to death, or a long lingering state of convalescence. On the contrary, Hydropathy acts upon a diametrically opposite system: by the imbibition of water, containing as it does an excess of oxygen, the vital forces are sustained, the blood is decarbonised, the appetite improved, the bowels regulated, etc. etc. _Fever._--An English officer who caught a fever twenty years ago in the West Indies, wrote to Priessnitz that all his prospects in life were blighted, and that existence was almost intolerable. He came to Gräfenberg and was treated as follows: Early in the morning packing-sheet and bath; wore heating bandage always. Breakfasted at eight o'clock, when, from nine o'clock until five o'clock in the evening, he was ordered to change the waist bandage every ten minutes. At five o'clock packing-sheet and bath. If ague appeared, which it did sometimes, then rubbing-sheets, well wrung out were applied with great friction until the fit was over. This patient was perfectly cured in three months. _Nervousness and slow Fever, and disposition to a Decline._--A lady was treated as follows:-- Morning, five packing-sheets and bath, 62°; noon, douche and sitz-bath; afternoon, rubbing-sheet and two sitz-baths. At first, she was ordered to have a cold bath prepared by the bed-side at night, and when fever and sweating came on, to go into the bath, and repeat it if necessary. She had a bad cough at the time; her friends thought such a proceeding would end in her death; the patient, however, recovered from her fever and cough, and left much improved in health. On awaking in the morning with distracting head-ache, parched tongue, and all the concomitants of fever, a lady was put into a packing-sheet; in twelve minutes, head-ache ceased. After remaining enveloped an hour or two, rubbing-sheets were applied, followed by a sitz-bath of twenty minutes: she drank water freely. This one application effected a cure. A young lady had her foot and ankle much swollen from rheumatic gout. Second day, arose with head-ache and pain in all her limbs; and towards evening, had a slight fever. For this, she was put into a tepid bath 62°, and rubbed for forty minutes, when the arm-pits feeling no warmer than the other parts of her body, she was allowed to leave the bath. This application was sufficient.
