the additament of the faline to the 

 metalline particles. 



And that part offuch additaments 

 is, (retained," may not only be found 

 by weighing, but in divers cafes 

 may bfe argued from what is obvious 

 to the Eye : as if you diflblve Mer- 

 cury ifi Aquafortis^ and into the phil- 

 tratedfolution dropfpirit of Salt, or 

 falt-water, or an urinous fpirit, as of 

 Sal Armoniac, you will have a very 

 White Precipitate} but ifinftead of 

 anyofthefe, you drop-in deliquated 

 fah of Tartar, your Precipitate will 

 be of W brick or orange colour. 

 From v^hsch experiment and fome o- 

 thers I would gladly take a rife to 

 pefrfwdd£ Chymifts and Phyfitians, 

 chat 'tis not fo indifferent, as thofe 

 ieem to think who look on Precipi- 

 tatioivbutas a kind of Comminution, 

 by what means the precipitation is 

 performed* For by rfcaibn of the 

 ftrift adhefion of djvers faline par- 

 ticles of the precipitant and the fol- 

 vent 3 the precipitated body, not- 

 withftanding all the wonted abluti-
