before. And upon tryal it appears, Firft, that two Ounces of Water 
will diffolve three Ounces of Loaf-Sugar and no more, except the 
Water be heated. i 
19. §. Thefame quantity of Water that is, two Ounces will dif 
folve above two Ounces of Salt of Tartar. 1 fay above, for how much 
more, want of a greater quantity of Sa which I could confide in, 
made me that I could not finifh the Experiment. 
40. §. The fame quantity, /¢. two Ounces of Waier, diffolveth an 
Ounce and a Drachm of Green Vitriol. 
21. §. The like quantity diffolveth fix Drachms and a Scruple or 
above 3 of an Ounce of common Sait. 
22, g. Of Nitre, Five Drachms two Scruples and an half. 
23. §. OfSal Armoniac, five Drachms and two Scruples. 
24. 9. Of Alum, not above two Diachms and a Scruple. 
ag. §. And of Borax, not above a Drachm and half a Scruple. 
26. §. Ofthefenote, That although Common Sait be very diffo- 
luble, and will prefently catch the moyfture of the Aer: yet a much 
greater quantity not only of Salt of Tartar, but even of Loaf sugar, 
and of Greer Pitriol it felf, may be diffolved in Water than of Common 
Salt. : 
27. §. Again, as the great Solubility of fome, fo the lefS Solubility 
of other Salts is alfo obfervable, as of Alum, and Borax. For the fame 
quantity of Water will diffolve near four times as much of Green Vitriol, 
as it will of Alum. And of Sugar more than ten times as much. Of 
Green Vitriol near eight times as much as of Borax 5 and of Sugar, twen- 
ty times as much, 
28. §. Fromthis Experiment we are likewife cautioned, not only 
in the Infufion of feveral Ingredients together, but of any one fingly 5 
that fuch a proportion thereofto the Menftraxum, be not exceeded. 
Forall that is over and above what the Adex/trun will bear,is either not 
extracted, or will be precipitated. Asis evident not only in the Di//o- 
lution of the Salts above named, but inthe Infusion of Phanis themfelves: 
as, for inftance; of Sezza; two Drachms whereof will impregnate 
four Ounces of Water as {trongly,asif twice the quantity were infufed 5 
pre the Water willbear no more of the Purgative Parts of that 
ody. 
29.°§. There is only one Sa/¢ more remaineth to be fpoken of un- 
der this Experiment 5 and that is, the Cryftals of Tartar. Whereof, 
it is {omewhat ftrange to obferve, that it will {carce at all diflolve in 
Water : not more, than even divers Refizous Gums, as Maftick, Tolu; 
Tacchamahacca, and fome others will do. For if two Drachms, fup- 
pofe of thee Cryfals, of Tartar (commonly fold for Cremor Tartar: ) 
be put to one Ounce of Water, fcarce five Grains thereof will, by Agi 
tation, be therein diffolved.
