Let. IV. Salts of Planis.. 263 
9. §. The Figure of thele Cryftals is angular and oblong, moft of 
them about the fifth, fixth or feventh of an Inch; but none of them 
very regular. Yet weare not hence to conclude, but that with the 
help of fome Circumftances which might be wanting in the fhooting of 
thefe 5 fome portion of regular ones may be obteined from this, as well 
as other Lixivial Salts hereafter mentioned. 
to. §. They are fommewhat tranfparent, and of a dark Ambar Co- 
lor, or like that of brown Sugar-Candy. Of a quite different Ta/fe 
from that of the Solutiox or Lee out of which they are bred 5 being not 
at all Lixzvial, but very weak and mild; not Ss, but Bitter in a 
good degree. 
11. §. It isalfoobfervable, that Alkaline and Acid salts being both 
poured feverally upon thefe Cryffals, they ftir not, nor are any way 
affe&ed witheitherofthem. So that thefe Cry/tals are no fort of Tare 
tar, or Tartareows Salt. Asis plain, from the manner of their Genera- 
tion, Tartar being {till bred in clofe Vefeéls; thefe never, but by expo- 
fing the Liquor to the Aer. As alfo from their Tus#e, being not fower, 
in the Jeaft, but bitter. And in that Tartar will make a Bullition with 
Alkaline Salis, which thefe will not do. Upon which accounts it ap- 
pears, that they are a Salé different in Nature from all other Salis 
hitherto known, or anew Species added to the Inventory of Nature. © 
12. §. Thefe Cryé#als within the fpace of about a fortnight after 
their firft Geveration, did alfo ceafe to {hoot any more, but only in- 
creafed alittle intheir Bulk, After which time, I dayly expected to 
fee the produétion alfo of atrue Marine Salt. And about two months 
after the faid E/fential Crystals had done fhooting, and not before, this 
alfo began to fhoot, in many finall Cry/fals, and at the top of the Solz- 
tion, as the other did, ftill falling ‘to the bottom as they grew 
biger. 
oo §. The Size of moft of them was near that of the Fiskes or 
Grains of Bay-Salt. The Colour of fome of them white, of others traz~ 
fparent s and of others white in the Cevtre, with tranfparent Edges 5 as 
is alfo ufual in the Cryftals of Common Salt. 
14. §. The Figure of moft is a perfect Square, and of very many 
coming near to'a Cubes which is alfo the Figure of Common Salt, and 
feldome an exact Cube. An exact Cube, being the conftant property of 
no Marine Sali, that 1 know of, except that of the Dead Sea. Divers Tu, 84: 
of them were alfo raifed as it were by feveral fteps from a deep Centre 
tothe Top: as is often feen in the common fhooting of Common salt 5 
and not in any other. Their Tae is neither Lixivial, as that of the 
Solution out of which they fhoot 5 nor bitterifh, as that of the E/ex- 
tial Cryftals; nor foweribh, as that of Tartar; but the perfect Laffe 
of Common Salt. 
15. g. It is alfo to be noted, That if Oy/ of Viiriol, and fome other 
{trong Acids, be poured upon this artificial Sea-Salt, they make an Ef- 
fervefcence together : but if Spirit of Salt or Spirit of Nitre either be 
poured on it, though it be never fo ftrong it ftirrethit not. In both 
which, and all the formentioned refpedts, it anfwers to the Properties of 
2 Marine or Common Salt, which no other Salt doth. 1 conclude it there- 
fore to be a true Marine Salt produced by Aré in the imitation of Nae 
ture.
