ken from him four or five times in considerable quantity, with 

 gentle cathartics, with calomel, diluents, and cool air, and he 

 recovered without any figns of delirium, or inflammation of the 



meninges of the brain. Mr. W , a ftrong corpulent 



m<- >f inferior life, had eryfipelas over his whole head, with 

 ili d pulle : he was not evacuated early in the difeafc 



through the timidity of his apothecary, and died delirious. Mrs. 



f had eryfipelas on the face, without either ftrong or weak 



pulfe; that is, with fenfitive fever alone, without fuperabun- 

 dcuice Or deficiency of irritation ; and recovered without any but 

 natural evacuations. From thefe three cafes of eryfipelas on the 

 head, it appears that the evacuations by the lancet muffc be ufed 

 with courage, where the degree of inflammation requires it ; 

 but not where this degree of inflammation is frnall, nor in the 

 eryfipelas attended with inirritation, as defcribed below. 



M. M. Venefection repeated according to the degree of in- 

 flammation. An emetic. Calomel, three grains every other 

 night. Cool air. Diluents, emetic tartar in fmall dofes, as a 

 quarter of a grain every fix hours. Tea, weak broth, gruel, lem- 

 onade, neutral falts. See Sect. XII. 6. 



Such external applications as carry away the heat of the fkin 

 may be of fervice, as cold water, cold flour, fnow, ether. Be- 

 caufe thefe applications impede the exertions of the fecerning 

 velTeis, which are now in too great action ; but any applica- 

 tions of the ftimulant kind, as folutions of lead, iron, copper, 

 or of alum, ufed early in the difeafe, muft be injurious *, as they 

 flimulate the fecerning vefTels, as well as the abforbent veflels, 

 into greater action ; exactly as occurs when ftimulant eye wa- 

 ters are ufed too foon in ophthalmy. See Clafs II. I. 2. 2. 

 But as the cuticle peels oiTin thiscafe after the inflammation ceaf- 

 es, it differs from ophthalmy ; and ftimulant applications are 

 not indicated at all, except where fymptoms of gangrene appear. 

 For as a new cuticle is formed under the old one, as under a blif- 

 ter, the ferous fluid between them is a defence to the new cuti- 

 cle, and fhould dry into a fcab by exhalation rather than be re- 

 abforbed. Hence we fee how greafy or oily applications, and 

 even how moid ones, are injurious in eryfipelas *, becaufe they 

 prevent the exhalation of the ferous effufion between the old 

 and new cuticle, and thus retard the formation of the latter. 



Eryfipelas inirtitatum differs from the former in its being at- 

 tended with weak pulfe, and other fymptoms of fenfitive inir- 

 ritated fever. The feet and legs are particularly liable to this 

 eryfipelas, which precedes or attends the fphacelus or mortifica- 

 tion of thofe parts. A great and long coldnefs firft affects the 

 limb, and the eryfipelas on the fkin feems to occur in confe- 



quence
