that time contraded the Stone in the ^/^«^Vj-jWhich Plant 
he much difcomiiiends as well as the l^apham, upon the 
fcore of their ill felit, for difpofing the Kidneys to pu- 
trefacftion, and fo to breed the Stone. Much might be 
faid to invalidate this Hypothejis : but the common and 
innocent ufe of theleP/ nts will fecure m againft this pre- 
judice, upon which Ohfervatiun his Hypothejis feems whol- 
ly to depend. 
We may alfo except againft the Experiment of Coa- 
^ulation^ upon £he mixtures ok high rectified Spirits of 
Vrine and Wifie, which if warily managed Will make a 
Coagulum with fuch expedition as feems very ftrange and 
furprizing: for this C^?;2f:r^^/c;2 will eafily be diflblved by 
water. In like manner if either of lYio. Spirits be very 
phlegmatic^ there will fo-low no Coagulation. In fo much 
that the Jiumours of tho, human contain too much 
water in them to admit fuch an EfFedt, eveninthofe Con- 
Jiitutions thzz haveufed themfeli^es to i^ery highly redlifi- 
cd Spirits, Moreover Horfes, Doggs and other Jnimals 
that drink no rvine are not free from this^r^^^^ Cementati- 
on, Nor could I ever difcover any drop of vinous Spirits 
afforded upon our Diftillation of thi$ matter. I would 
not be thought here to excniQthcfc Ardent Spirits from 
doing mifchief to the human body, but doe believe that 
they are apt enough to make ill Secretions and fome Con- 
cretions of the humors, (tho of an other fort) I mean fuch 
as, are vifible enough in tliQ faces of Great drin^rs and the 
like. Nor is this difagreeable to our experiments, where 
tho* the diluted and weakened5/?m>x will not convene in- 
to a firm hardened body, yet fome leffer and fofter Con- 
cretions will Subfide to the bottom of the G/<^/i'. 
We may alfo queftion the Hypothecs of the FroduSlion of 
the Stone by PetrefaBion, Stones are fuch fixt bodys 
that they yield nothing upon Dijlillation except a fmall 
Quantity
