the great Similitude there is therefore in fa 
many Refpeds, between thefe two Subftan- 
ces, we may well look upon the Calculus as 
a true Animal Tartar^ and doubtlefi gouty 
Concretions arc the fame. 
7. Animal Tartar I would call it in Contra-^ 
diftindion to Vegetable Tartar \ for as animal 
and vegetable Subftances greatly differ in their 
Saks and Sulphurs when chymically analyfed, 
fo do alfo their refpedive Tartars : But then 
they are found exadly to agree in thefe remark- 
able Properties, viz. That they are both formed 
not barely as a Sediment at the bottom of their 
Liquors ; but being equally expanded and 
feparated from all parts of their Fluids, they 
adhere uniformly to the Sides of their containing 
Veffels in the Form of a hard Cruft: Thofe 
Particles which are immediately next the Sides 
of the VeflH being firft attraded and adhering 
to them. And as it is a known and wonderful 
Property of Fluids, to difFufe what is mixed 
with them equally fn every part, fo when part 
of thefe inemfting Particles are attraded out 
of the Fluids, the remaining Particles equally 
diftnfing themfelves, a new Succeftion of them 
is thereby brought within the Atcradion of the
