nated Liquor, I let fall a fit proportion, for inftafice 
Four or Five drops, of a very ftrong and well filtrated ^ 
Solution of well-refined Silver, diflolv'd in clean Aqua 
Fortis ; [for a fhift, common or Sterling Silver will ferve 
the turn:] And I made the Experiment Tiicceed with Spi- 
rit of Nitre, inftead of Aquafortis, upon which there im- 
mediately appear'd a whiufll Cloud,which tho'but (lowly, 
defcended to the bottom, and fettled there in a white 
Precipitate. 
This Experiment having been feveral times, for the V, 
main of it, reiterated with Succeis, I thought fit to keep 
conftant to the way of Probation I made ufe of in it, 
(and which Trials had recommended to me for between 
20 and 30 Years) tho' (by reafon of fome things that 
Haft forbids me to mention) I pitch'd upon this way 
without at all denying, that Men of Sagacity, efpecially 
if well vers'd in Chymical Operations, may upon the 
fame ground that I went upon, find fome other and cheap- 
er ways, tho' (carce any more nice and certain, of com* 
paOing the fame end. 
After what has been hitherto faid, I prefume I may VI 
feafbnably proceed, to fubjoyn the four enfiurg Adver- 
tifements. 
And Firft, I fiiall give notice, that, to make the Ex- 
periment rather feverely, than at all favourably, there 
was ufually taken fomewhat more than a thoutand parts 
of Water to one of Salt. 
Next, I obferv'd, that having let fall a few drops of Vfl. 
our Metalline Solution, into the Liquor obtain'd from 
Sea water by the Patentees way of Sweetning it,there did 
not prefently enfue any white Cloud or precipitate,much 
lefs iuch an one as had bee newly afforded by the Water, 
that was impregnated with lefs than a thoufandth part 
! of Salr. Ana it after fome time i\\zrz happen d to appear 
I (for 'tis not abfolute necefiary it fliouldj a little Clowdi- 
nefs in this Factitious Liquor, it was both flowlier pro-
