fever. On the fecond day red fpots, like parts ftung with net. 

 ties, are feen ; which almoft vanim during the day, and recur in 

 the evening with the fever, fucceeded in a few days by very mi- 

 nute fcales. See Tranf. of the College, London. 



17. Aphtha. Thrufh. It has been doubted, whether aphtha 

 or thrufh, which confifts of ulcers in the mouth, mould be enu- 

 merated amongft febrile difeafes ; and whether thefe ulcers are 

 always fymptomatic, or the confequence rather than the caufe of 

 the fevers which attend them. The tongue becomes rather 

 fwelled 5 its colour and that of the fauces purplifh ; floughs or 

 ulcers appear firft on the throat and edges of the tongue, and 

 at length over the whole mouth. Thefe floughs are whitifh, 

 fometimes diftincl:, often coalefcing, and remain an uncertain 

 time. Cullen. I fliall concifely mention four cafes of aphtha, 

 but do not pretend to determine whether they were all of them, 

 fymptomatic or original difeafes. 



Aphtha fenfttiva. A lady during pregnancy was frequently 

 feized with ulcers on her tongue and cheeks, or other parts of 

 the mouth, without much apparent fever ; which continued two 

 or three weeks, and returned almoft every month. The thrufh 

 in the mouths of young children feems to be a fimilar difeafe. 

 Thefe ulcers refemble thofe produced in the fea-fcurvy, and have 

 probably for their caufe an increafed action of the fecerning 

 fyftem from increafed fenfation, with a decreafed action of the 

 abforbent fyftem from decreafed irritation. See Clafs I. 2. i. 14, 



M. M. Solutions of alum, of blue vitriol. Powder of bark 

 taken frequently into the mouth in very fmall quantity. See 

 Clafs II. i. 3. i. 



Aphtha Irritata. Inflammatory aphtha. A cafe of this kind 

 is related under the title of fuppurative rheumatifm. Clafs IV. 

 2. i. 16. 



Aphtha inirritata. Slotighs or ulcers of the mouth, attended 

 with fenfitive fever with great arterial debility. They feem to 

 fpread downwards from the throat into the (lomach, and proba- 

 bly through the whole inteftinal canal, beginning their courfe 

 with cardialgia, and terminating it with tenefmus ; and/might 

 perhaps be called an eryfipelas of this mucous membrane. 



M. M. Cool air. A fmall blifter on the back. Bark. Wine. 

 Opium in fmall repeated quantities. Soap neutralizes the gaf- 

 tric acid without cffervefcence, and thus relieves the pain of car- 

 dialgia, where the ftomach is affected. Milk alfo deftroys a part 

 of this acid. Infufion of fage-leaves two ounces, almond-foap 

 from five grains to ten, with fugar and cream, is generally both 

 agreeable and ufefui to thefe patients. See I. 2. 4. 5.
