2. Tf you keep the Lye to evaporate by the Fire in 
Veflels of Earth Glafed, you will lofe a great Quantity 
of the Salts, for that as the Lye' grows thicker, the Salt 
penetrates the Bottom and Sides of the Veflel of Earth, 
and is loft. 
3. The Quantity of Water to make the Lye of is not 
determined ; for the moft part ftfc of Water w ill extrad 
all the Salt from itb of A(hes. 
4. The Afhes whereof vVe have already made the Lye, 
and by Confequence drawn out the Salt, may, if you 
burn the fame again in a Brick Furnace, make you after- 
wards another new Lye, which ufually yields fome fmall 
Portion of Salt. 
5. The Salts drawn in the manner aforefaid,when the 
Air is Moift ufe to melt, to obviate this Inconvenience, 
when you burn the Materials to reduc^them to Adies, 
'tis requifite to ufe with them a due Quantity of Sulphur, 
and if it happen the Arties fliould be made to your Hand, 
you may mingle them with Sulphur, and keep the fame 
to the Fire till fuch time as it be burnt. By this Means 
the Salt will never come to run, but become more White 
and Chriftalline. 
6. There is no General Rule concerning the QiJantity 
of Sulphur to be put into the Materials you thus Burn ; 
you may neverthelefs at a guefs fay, to a Hundred Pounds 
of Materials 4 or 5 5 of Sulphur are ufually fufficient. 
7. All the Salts have a peculiar and determined Figure, 
the which they always keep, altho' they are often refol- 
ved into Water, and afterward congealed. 
8. If in One only Liquid you diflblve together Two 
or Three forts of Salt of different Figure, when they con- 
geal) they all affume their ancient and Proper Figure,and 
this nor only happens in Fa^litious^ but alfo in Mineral 
Salts. If in a Veflel full of Water you diffolve equal or 
unequal Quantities of Vitriol of Cypru^^ Rocb Allum,
