fever. On the second day red spots, like parts stung with net- 

 tles, are seen; which almost vanish during the day, and recur in 

 the evening with the fever, succeeded in a few days by very 

 minute scales. See Trans, of the College, London. 



17. Jlphtha. Thrush. It has been doubted, whether aphtha 

 or thrush, which consists of ulcers in the mouth, should be enu- 

 merated amongst febrile diseases; and whether these ulcers are 

 always symptomatic, or the consequence rather than the cause of 

 the fevers which attend them. The tongue becomes rather 

 swelled; its colour and that of the fauces purplish; sloughs or 

 ulcers appear first on the throat and edges of the tongue, and at 

 length over the whole mouth. These sloughs are whitish, some- 

 times distinct, often coalescing, and remain an uncertain time. 

 Cullen. I shall concisely mention four cases of aphtha, but do 

 not pretend to determine whether they were all of them symp- 

 tomatic or original diseases. 



Jlphtha sensitiva. A lady during pregnancy was frequently 

 seized 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 almost every month. The thrush in 

 the mouths of young children seems to be a similar disease. These 

 ulcers resemble those produced in the sea-scurvy, and have pro- 

 bably for their cause an increased action of the secerning system 

 from increased sensation, with a decreased action of the absorbent 

 system from decreased irritation. See Class I. 2. 1. 14. 



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

 taken frequently into the mouth in very small quantity. See 

 Class II. 1. 3. 1. 



Jlphtha irritata. Inflammatory aphtha. A case of this kind 

 is related under the title of suppurative rheumatism. Class IV. 

 2.1.16. 



Jlphtha inirritata. Sloughs or ulcers of the mouth, attended 

 with sensitive fever with great arterial debility. They seem to 

 spread downwards from the throat into the stomach, and probably 

 through the whole intestinal canal, beginning their course with 

 cardialgia, and terminating it with tenesmus; and might perhaps 

 be called an erysipelas of this mucous membrane. 



M. M. Cool air. A small blister on the back. Bark. Wine. 

 Opium in small repeated quantities. Soap neutralizes the gastric 

 acid without effervescence, and thus relieves the pain of cardial- 

 gia, where the stomach is affected. Milk also destroys a part of 

 this acid. Infusion of sage-leaves two ounces, almond-soap from 

 five grains to ten, with sugar and cream, is generally both agree- 

 able and useful to these patients. See I. 2. 4. 5.
