12. §, None of thefe E/éntial Cryftals have any hot fiery Laffe, but 
are very mild, and fenfibly Bitter ; efpecially, about the Roof of the 
Tongue: as is alfo obfervable of fome Plants hereafter mentioned, in 
{peaking of the different Taftes of Plants. 
13. §. Oy! of Vitriol droped upon thefe Cry/tals doth not affect 
them in the leaft: yet droped into the feveral Solutions out of which 
the Cryftals are produced, immediately caufeth a great Effervefcence, 
14. §. Ofthe Solutions above named, that, of Salt of Tartar was 
the 6th. Whereof it is remarquable, That having waited feveral 
Months together, I could not obferve the leaft Effential Salt to be 
therein produced in all that time. Whether there be any other Vege. 
table Salts, befides this of Tartar, which will not yield the Efential 
above defcribed, I have not yet experimented. ; 
5. §. Inthe mean time, from the Premifes it is very probable, 
that moft of them afford more or fewer of the faid Cryftals. In regard 
they are Plants of a very different kind, which I made tryal upon: 
as Garden Scurvygrafs, very Hot 5 Rofemary, very Arouatich. Worm. 
wood very Bitter 3 Black Thorne, Aftringent and Sower. And it is alfo 
plain, That the faid E/extial Salts contained in the Lixivial, are not 
altogether one and the fame, - but of divers Sorts. 
16. §. ABOUT 7 or 8days after the Effential CrySfals were produ- 
ced; the Marine Salt did alfo begin to fhoots, firft in Rofemary; quickly 
after, in Scuroygra/s; Next, in Black Thorn and Wormwood, fc. after 
the fpace of a week or 10 days more. And inall of them with fome 
difference of Size and Figure. 
17. §. The plaineft of all, was that produced out of the Swit of 
Black Thorn, confifting for the moft part of very finall Crsfeals, not 
above the 15% of an Inch fquare, as alfo thin, fhaped like a Duch Tile 
ufed for Chimnies. Many others were very thick, and near to a 
Cube. Moft of which were a little hollowed in the midle, like a grind- 
ing Marble or Salt-Celler ; and the hollow bounded by 4 plain and 
equal Sides, all defcending a little towards the Centre ; and meafured 
by two crofs Lines, which ftaid upon the four Angles of the Square y 
and fo cut one the other at Right Angles. Both which Properties 
are likewife ufually feen in the Cry/tals of Common Salt, 
18. §. In Wormwood, many of thefe Cryftals, befides the plain 
Ones, were figur'd crofsways like a Dagger-Hilt, Which was fome- 
times naked, and fometimes inclofed in a quare andalmoft Cubical Box. 
Many others were figur’d into Sprigs made up of four chief Branches 
{landing crofswife, and thofe fubbrancheds and all the Branches made 
up of little (quare Cryffals, cluftered together in that Figure. The 
Sprigy Figure of thefe Cryffals is not accidental, but hath conftantly 
come after they hadbeen three times diffolved, and the Solution expo- 
fed to evaporate. 
19. §. The Marize Salt of Rofémary hath alfo fome variety. For 
befides the plain ones above defcribed, there are fome thick Sqaares, 
which have alfo a {quare hollow defcending by five, fix, or feven nar- 
row fteps, towards the Centres being in Figure, faving thefe Steps, 
fomewhat like the Hoper in a Mil. 
20. §. Upona fecond Solution of the fame Salt, there fhoots an- 
other fort of {quare; which is not plain on the edges, as the above- 
named, but fcalloped or florid all round about, not unlike the Leaves 
of fome Plants. 21. ¢.
