9. $. The Figure of thefe Cryflals is angular and oblong, molt of 
them about the fifth, fixth or feventh of an Inch; but none of them 
very regular. Yet we are not hence to.conclude, but that with the 
help of fome Circumftances which might be wanting in the fhooting of 
thefe ; fome portion of regular ones may be obteined from this, as well 
as other Lixivial Salts hercafter mentioned, 
10. $. They are fomewhat tranfparent, and of a dark Ambar Co- 
or, or like that of brows Sygar-Candy. OF a quite different Tao 
“j from that of the solution or Lee out of which they are bred; being not 
dy 
at all Lixivial, but very weak and mild ; not Sst, but Bitter in a 
The good degree. 
11. $. It is alfo obfervable;, that Alkaline and Acid Salts being both 
x poured feverally upon thefe Cryftals, they ftir not, nor are any way 
lo affested with either of them. So that thele C7y/2als are no fort of Tar- 
pet tar, or Tartareows Salt. Asis plain, from the. manner of their Gexera- 
tions Tartar being {till bred in clofe Vefels 3, thele never, but by expo: 
ad fing the Liquor to the Aer. „As alfo from their Taife, being not fower, 
ye in the leaft, but bitter. And in that Tartar will make a Bullition with 
Alkaline salts, which thefe will not do. Upon which accounts it ap- 
pears, that they are a Salt different. in Nature from all other Salts 
hitherto known, or anew Species added to the Inventory of Nature. 
12. $. Thele Crystals within the {pace of about a fortnight after 
their firft Generation, did alfo ceafe to {hoot any more, but only in- 
mr creafed a little in their Bulk, After which time, I dayly expected to 
pa fee the produétion alfo of a true Marine salt... And about two months 
jal after the faid Efential Crystals had done fhooting, and not before, this 
alfo began to thoot, in many fmall Cry/tals, and at the top of the Soly- 
,¢ tion, as the other did, (till falling to.the bottom as they grew 
t biger. 
a E $. The Size of moft of them was near that of the Flakes or 
k Grains of Bay-Salt. The Colour of fome of them white, of others tran- 
S fperents and of others mbitein the Centre, with tranfpärene Edges sas 
is alío ufual in the Cryftals of Common Salt. 
ls 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 2 
= Fldome an exaét Cube. An exatt Cube, being the conftant property of 
be no Marine Salt, that I know of, except that of the Dead Sea. Divers Tab, 83. 
m 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 ; 
and not in any other. Their Tafe is neither Lixivial, as that of the 
Solution out of which they fhoot 5 nor bitterifh, as that of the Effen- 
tial Cryflals; nor fowerifh, as that of Tartar ; but the perfect Tafe 
of Common Salt. 
15. $. It is alfo to be noted, That if Oy/ of Vitriol, and fome other 
ftrong 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 ftrongit ftirrethit not. In both 
which, and all the formentioned refpedts, it anfwers to the Properties of 
a Marine or Common Salt, which no other Salt doth. I conclude it there- 
fore to be a true Marine Salt produced by Art in the imitation of Nee 
ture.
