264 Effential and Marine Lea. VE 
CHAP. IL 
Wherein is fhewed, That the faid. ESSENTIAL 
and MARINE Salts of Plants are both of different 
Sorts. 
=JA VING madethe Experiment, that both an 
GAN) Effential and Marine Salt may be produced out 
| of the Lixival Salt of a Plant. I thought it 
probable, that neither the one nor the other, 
was always the fame, but that as they had their 
general properties which made them to be of 
two general |kinds 5 fo they might have fome 
fpecial property, for the diftinguithing of each 
kind into feveral Sorts. And withall, that 
in a warmer feafon, than before taken, the Tryal hereof might be 
finifhed in a fhorter time. s 
2. $. For the making'öf which, I conceived it requifiteto remove 
an Opinion which feemed to lye in my way; fe. That there is little 
or no difference between the feveral Lixivial Salts of Plants, as fome 
Learned men have thought. But either there is a difference, or not: if + 
not, it fhould be proved : and if there be,it fhould then be juftly fated, 
what that difference is. For the doing of which, I chofè this Method, I 
took an equal quantity of the whiteft and pureft Salts of divers Plants, 
all made by an equal degree of Calcimation 5 and diffolved them all fe- 
verally in an equal quantity of water. And pouring likewife an equal 
quantity, as about 10 or 12 drops of each into a fpoon, Itafted them 
feverally. Whereby it was very evident, that they were not all of one 
Taft, but of very different ones, both as to ftrength and kind: and 
therefore different in Nature alfo. The Salts I made tryal of were 
thofe of Sorrel, Anife, Wormwood, Mallow, Afh, Tartar and others : 
and upon half a Drachm of each I poured 3ijf8 of water. The Sol- 
tions are here prefent to be tafted. By which the differences will ea- ug 
fily be obferved, and particularly that the Salt of Wormwood or Scur- Ne 
aygrafi, is almoft as {trong again asthe Salt of Avifé, orSorrel: and that Na 
the Salt of A is above twice as ftrong, and that of Tartar above » 
thrice as ftrong, as that of Sorrel, and almoft thrice as {trong asithat of 
Wormwood or Scnroygrafs. So that he who (hall give half a Scruple, 
fuppofe of Salt of Tartar 3 inftead of half a Scruple of Salt of Worm- 
wood, or other like Salt; he may as well give a Scruple of Rofi» of 
Jalap, for a Scruple of the powder, or almoit three! Drachms of Rba- 
barb, or other like Purge, inftead of one. And the like is to be fiid 
of other Lixivial Salts in their degrees, 
/ 3. $. Having obferved thus much, I proceeded to repeat the for- 
mer Experiment, with fome ofthe aforefaid, and fome other Y 
Salts, the beft calcin'd, and the pureft, that could be made for this 
purpofe, being thele Six Salts, fe. of Rofemay, Garden Seurrygrafi,
