The following modes of treatment and cases will enable the practitioner to judge how he should treat his patient as circumstances may arise. As general rules:-- In the cold fit, use rubbing-sheets well wrung out, with a slight interim between each until the hot stage is produced. In the hot stage packing-sheets should be changed as often as necessary. In Typhus I have known them changed forty or fifty times in a day. The bath which ought at first to be a little tepid and cooled by degrees, should be resorted to at intervals twice or thrice a day, from a quarter of an hour to an hour. Should the heat action be prematurely violent, or likely to end in inflammation, resort to a sitz-bath with or without a foot-bath, instead of the tepid bath, particularly where either the brain, organs of sense, or those within the thorax are at all engaged. Rubbing-sheets, in certain cases where the vital energies are weak or languid, will be sufficient to suppress a febrile paroxysm. Their renewal and time of application must entirely depend on the age, strength and idiosyncrasy of the case: water should be drunk in small quantities, and frequently. Where the brain is attacked, water must be constantly applied to that locality, so as not to allow of an increase of temperature. Where there is no want of bodily strength in the patient, the quickest and surest method of putting an end at once to fever, is as follows. Put him into a bath up to the shoulders, tepid 63° or 64° to begin with, and to be renewed constantly by cold water being poured over the shoulders; two persons rubbing the patient the whole time. When he is quite fatigued, take him out, dry the body and throw the window open for air; when recovered a little, renew the operation, and so on for the third time if necessary. Then dress and go out to walk. Drink plentifully of water. If very cold on coming out of the bath, walk without the body bandage, but put a large thick one from the hips to the arm-pits on returning home. Let the patient rest two or three hours; and if fever return repeat the foregoing treatment. A Mr. B----, who was greatly debilitated, had, for fever, a tepid bath for half an hour to an hour and half; also many rubbing-sheets; on one occasion as many as twenty-nine in a day. If the fever resist the above treatment, then resort to the packing-sheet. Dr. L----, for fever, ordered, five or six rubbing-sheets in succession. Head bath for a quarter of an hour. Bandage from hips to arm-pits, to be changed often, even in the night; to be much in the open air.
