before. And upon tryal it appears, Fir(t, that two Ounces of Water 
will diffolve three Ounces of Loaf-Sigar and no more, except the 
Water be heated. 
19. $. The fame quantity of Water that is, two Ounces will dit 
folve above two Ounces of Salt of Tartar. I fay above, for how much 
more, want of agreater quantity of Salt which I could confide in, 
made me that I could not fini(h the Experiment. 
20. $. The fame quantity, fè. two Ounces of Water, dificlveth an 
Ounce and a Drachm of Green vitriol. 
21. $. The like quantity diffolveth fix Drachms and a Scruple or 
above } of an Ounce of common Salt. ? 
22, $. Of Nitre, Five Drachms two Scruples and an half. 
23. $. OfSal Armoniac, five Drachms and two Scruples. 
24. $.. Of Alum, not above two Drachms and a Seruple. 
asi $. And of Borax, not above a Drachm and half aScruple. 
26. $. Ofthefe note, That although Common Salt be very diffo- 
luble, and will prefently catch the moylture of the Aer: yet a much 
greater quantity not only of Salt of Tartar, but even of Loaf sugar, 
and of Green Vitriol it felf, may be diffolved in Water than of Common 
Salt. 
27. $. Again, as the great Solubility of fome, fo the leß Solubility 
of other Salts is alfo obfervable, as of Alum, and Borax. For the fame 
quantity of Water will diflolve near four times as much of Green Vitriol, 
as it will of Alum. „And of Sxgar more than ten times as much. Of 
Green Vitriol near eight times as much as of Borax; and of Sugar, twen- 
ty times as much, 
28. $. Fromthis Experiment we are likewife cautioned, not only 
in the Lnfifion of feveral Ingredients together, but of any one fingly 5 
that füch a proportion thereof to the Menftrunum, be not exceeded. 
Forall that is over and above what the Menftrunm will bear,is either not 
extraéted, or will be precipitated. Asis evident not only inthe Difo- 
lution of the Salts above named, but inthe Infufton of Plants chemfelves: 
as, for inftance; of Sermaz two Drachms whereof will impregnate 
four Ounces of Water as ftrongly,asif twice the quantity were infuled 5 
becaufe the Water willbear no more of the Purgative Parts of that 
Body. 
29. §. There is only one Salt more remaineth to be fpoken of un- 
der this Experiment; and that is, the Cryftals of Tartar. Whereof, 
it is fomewhat ftrange to obferve, that it will fearce at all diflolve in 
Water: not more, than even divers Refinous Gums, as Maftich, Tolu, 
Tacchamahacca, and fome others will do. For if two Drachms, füp- 
pole of thele Cryftals, of Tartar (commonly fold for Cremor Tartari ) 
be put to one Ounce of Water, fcarce five Grains thereof will, bgi- 
tation, be therein diflolved.
