in this the pain only affects the patient during the 

 motion of the part, and from the fecond kind of 

 rheumatifm above defcribed, as it is not attended 

 with quick pulfe or inflammation. It is generally 

 believed to fucoeed the acute rheumatifm of the 

 fame p^rt, and that fome coagulable lymph, or cre- 

 taceous, or calculous material, has been left on the 

 membrane ; which gives pain, when the mufcles 

 move over it, as fome extraneous body would do, 

 which was too infoluble to be abforbed. Hence 

 there is an analogy between the chronic rheuma- 

 tifm and the difeafes which produce gravel or gout- 

 ftones ; and it may perhaps receive relief from the 

 fame remedies, fuch as aerated fal foda.
