9, To be brief. Whether the Th^inmenm of lofs of vertues 
in fuch Waiters may by an Hjfothefis of an inteftinc Precipitati-

(if not better^ explicated, than by the Hjf6thefis of an A- 
volationofSpiiicucus parts through all Vcffels and clofures 
whatfo^^verf 
Which Hypothefis that it may be the better weighed , I fhall 
only exhibit it , and leave itto the Ingenious and Learned to 
conclude concerning it. 
Fir [I therefore it is generally received amongftmoft, cfpe- 
Cialiy the morepolitc,Chymical Authors and Students, That, if 
any Medical vertues be in Minerals or Metals, it confifts m their 
Sulphurs 5 which are of a Volatile 2nd Alcalifate property • ef» 
pecially when not intimately conmmix' t with ^ or after com- 
mixtion perfe^ly freed from their Mercurial parts. 
Next , its as much received,even to become a Cymical Max-

Again they alike conclude , that S^lts aft bi ft in a State of
