III. An Account of the probable Canfes of the 
Fain in Kheumatifms ; as alfo of the Cure of 
a total Supprefjlon of Urine ^ not caufed by 
a Stone ^ by the ufe of Acids j as commtmt- 
cated by Dr. Edward Baynard, Fellovi? of the 
CoUedge of VhyficianSy London. 
THIS Ingenious Pbyfician was always of the O- 
pinion, that the Pains in a Rheumatifm were 
not caufed from any Saline or Acid Particles in the 
Blood, but rather from its Clamminefs and Deofity 
extending the Channels through which it pailes, which 
Extenfion produces thofe ftsarp and pungent Pains which 
Rheumatifinatick Perfons fo generally complain of; foral- 
tliough the proper Coats of she Veins and Arteries ftcm 
tp be indoknt in themfekes, yti thofe thin Membranes 
\j^hich obfide them are moft exquifite of Senfe, and full 
o{ tymfh^*du^Sy which being dilated and ffretch'd ^ 
caufe an Inflammatory Symptomatical Fever, with con- 
tinual Sweats ; the Blood being Glutinous and Seizy, as 
in Quinfies and Pleurifies, and all other Inflammatory 
Diftempers. The Fever being increafed by the grea^ 
ftore of Alkalial Corrofive Salts lodging in the Blood y 
caufing Thirft, ©"c. and not diluted and vvaih'd off by 
Urine, which Urine is always thick, turbid, and high- 
coloured, and almoft, if not totally devoid of any Sa* 
line Impregnations. To prove which, he fent fix C^iarts 
of a ftrong Man's Urine in the heighth of a Rheuma- 
tifm, to that Ingenious Artift Mr. George Moults who- 
Chymically Anatomized it, and found not above the 
'Thirtieth Part of thofe Salts, ufually found in fueh^ 
quantity of the Urine of a found Perfoo.
