which is produced by an Auftere only, or an Auftere 
Acid. 
Thefe Experiments being made and defcribed in or- 
der to explain the Nature and Caufes of a Rheumatifm, 
and the Gout, thefe Diftempers are next treated of. 
The Matter or Humour producing a Rheumatifm is 
made to have a different Nature in feveral Patients 5 in 
fome it is Acid, in fome Saline, and in others Acrious. 
This Matter whilft it lies in the Mafs of Blood, temperd 
with the other parts, fcarce gives any fenfiblc effeft : but 
the mucilaginous Glands between the Mufcles, (as we 
fee other Glands of the Body often do,) (erving iome- 
times for the Depuration of the Sanguineous Mafs, by 
feparating from it incongruous and morbifick Particles, 
this Matter fo feparatcd comes to be more ftrong and 
fincere, fo as to have a fenfible effeft upon the Fibres, 
pricking and irritating of them, and if the Matter be 
an Acid or Auftere, it affe&s the Mucilage it felf, fb as 
to coagulate it in the Interfaces of the Mufcles, which 
produces that Rheumatifm, which is fixt, and where 
the Blood is very fizy. 
As there is a difference in the Matter, which produces 
the Diftemper, fo it is to be treated with different means. 
Where the Matter is thin and acrious 5 with temperate 
and cooling Medicines, together with fuch gentle Dia- 
phoreticks, as have themfelves no Acrimony. Where 
the Humour is fait; with diluting and aqueous things 
together with fome Diureticks. And when the Muci- 
lage is coagulated with an Acid above other things, the 
moft proper Medicines leem to be fuch as diflblve a Coa- 
gnlum, fuch are Oleum Tartar* per deliqnium^ Spirit of 
Salt Armoniack, and Spirit of Harts-Horn. 
In the Gout the humour likewife is of a different 
Nature 5 fometimes Acid, or Saline, and fometimas Acri- 
ous. This Matter is (eparated in the manner of a Crip 
by the mucilaginous Gland&of the Joynts, where it al-
