imploy the way, whereby I have of- 

 ten quickly dilpatched it. As foon 

 then as Ih&ve diffblved a convenient 

 quantity, which needs not be a great 

 one, of Silver in cleanfed Aquafortis^ 

 I add twenty or twenty five times as 

 much of either diftilled water or rain 

 water i ( for though common water 

 will fometimes do "well , yet it fel- 

 dome does fo well 5 ) and then into 

 the clear folution I hang by a ftrilig a 

 clean piece of Copper, which will "be 

 prefently covered with little (hiding 

 plates almoftlikefcalesoffifh^ which 

 one may eafily (hake off and make 

 room for more. And this may illu- 

 ftrate what we formerly mentioned 

 about the fubfiding of metalline cor- 

 pufclcs,when they convene in liquors, 

 wherein, whilft they were difperfed 

 in very minute parts 5 they fwam 

 freely. Fdr in this operation the 

 little fcales of Silver feemed to be 

 purely metalline, and there is no fe- 

 line Precipitant, as Salt of Tartar or 

 of Urine, imployed to make them 



fubfide.
