Perhaps one of the most striking uses of water in diseased conditions is that which is produced by the process known as "packing." In cases of high fever, as for instance in typhoid, the patient experiences much relief and the fever is considerably reduced by wrapping in a wet sheet and keeping the patient therein for a considerable period of time. The sheet may be removed from time to time, washed in tepid water, and replaced. When a medical student I noticed in the wards of the typhoid hospital in Vienna, the general treatment of typhoid patients by giving them large doses of quinine and then immersing them naked in the bath, the temperature of which was high enough to produce no chill, that is, at a temperature of 85, 90 or 950. Gradually the warmer water would be drawn away from this bath and colder water substituted until the temperature of the bath would sink to 85, 80 or even 75o. Under this treatment the temperature of the patient rapidly fell and he was greatly benefited. It is probable that the therapeutic effect of water in the treatment of fevers of this description has not been properly appreciated by the medical profession.
