1 88 DISEASES Class II. i. 3.2, 



twice a day with cold vinegar and water, or cold fait and water, 

 or cold water alone, by means of a fpoage. If fome parts are 

 too cold, as the extremities,* while other parts are too hot, as the. 

 face or bread, cover the cold parts with flannel, and cool the 

 hot parts by a current of cool air, or bathing them as above. 



4. For the healing of ulcers, if in the mouth, folution of 

 alum in water about 40 grains to an ounce, or of blue vitriol 

 in water, one grain or two to an ounce may be ufed to touch, 

 them with three or four times a day. Of thefe perhaps a folu- 

 tion of alum is to be preferred, as it inftantiy takes away the 

 flench from ulcers I fuppofe by combining with the volatile al- 

 kali which attends it. For this purpofe a folution of alum of an 

 ounce to a pint of water fhould be frequently injected by means 

 of a fyringe into the mouth. If there are ulcers on the exter- 

 nal fkin, fine powder of bark feven parts, and cerufla in tine 

 powder one part, fhould be mixed and applied dry on the fore, 

 and kept on by lint, and a bandage. 



As Houghs in the mouth are frequently produced by the pre- 

 vious drynefs of the membranes which line it, this drynefs mould 

 be prevented by frequently moiftening them, which may be ef- 

 fected by injection with a fyringe, or by a moift fponge, or. laft- 

 lyin the following manner. Place a glafs of wine and water, 

 or of milk and fugar, on a table by the bedfide, a little above the 

 level of the mouth of the patient ; then, having previoufly moif- 

 tened a long piece of narrow lifting, or cloth, or flannel, with 

 the fame liquor, leave one end of it in the glafs, and introduce 

 the other into the mouth of the patient -, which will thus be fup^ 

 plied with a conftant oozing of the fluid through the cloth, 

 which acts as a capillary fyphon. 



The vifcid phlegm, which adheres to the tongue, fhould be 

 coagulated by fome auftere acid, as by lemon-juice evaporated 

 to half its quantity, or by crab-juice ; and then it may be fcra- 

 ped off by a knife, or rubbed ofFby flannel, or a fage-leaf dipped 

 in vinegar, or in fait and water. 



2. Eryftpelas. St. Anthony's fire may be divided into three 

 kinds, which differ in their method of cure, the irritated, the in- 

 irritated, and the fenfitive eryfipelas. 



Eryfipelas irritatum is attended with increafe of irritation be- 

 fides increafe of fenfation ; that is, with ftrong, hard and full 

 pulfe, which requires frequent venefection, like other inflam- 

 mations with arterial ftrength. It is diftinguifhed from the 

 phlegmonic inflammations of the laft genus by its fituation on 

 the external habit, and by the rednefs, heat, and tumour, not be- 

 ing diftinctly circumfcribed ; fo that the eye or finger cannot 

 exactly trace the extent of them.
