9. The fweet Acrid Aromaticks of tlie Faenil Clafs have alia 
Vola/ile Salt and a Volatile Oyl, as Angelica, Lovage, Parfly, 
Memii, Dill. Note, The Leaves and Roots, of Fknil contain a 
Vo/atile Oyl and Effential Salt, the Seed a Volatile (3yl and Salt ^ 
bi/t fince the Roots and Leaves have a pungent Tafte, there is alio 
9' Volatile Salt in them, tho the Ghymift do not obferve it. 
All the parts of Cariaways have the odor of Punaifes, except 
the Seed ^ from whence I may infer, that the foetid Plants have 
the fame principles as the Aromatics^ viz. a Volatile Oyl and 
Salt «5 and this is confirmed by other fatids which have them, as 
Rue and Afjafatida^ and Vulvar la, Veuceianum is defcibed ofr 
a bitter acid. Tefte^ with the odor of Pitch, and muft have a Vola- 
tile Salt, tho L' Emery defcribes only its effential Salt and Oyl ; 
So in Smallage he defcribes only the effential Salt and Oyl^ but 
its Acrid Tafte manifefts the Volatile Salt. 
10. The Sweet Gums, as Marina, Sarcocolla, contain much 
Oyl and effential Salt ^ tho Honey and Sugar have more effential 
Salt than Oyl-, by which we may obferve how much effeno'al Salt 
is in all Sweets, and why they are apt to turn fowre, and ferment ^ 
and from fuch fweet Gums all fweet Plants have their Acid and 
Oyl upon Diftillation, 
11. CitruUs, Melons, Gourds, Cucumbers, which are bittet 
Sweets, and very mucilaginous, contain much Oyl and little Salt. 
Since the whole Claffes of Sweet Plants contain an Oyl and 
fential Salt, fome more fome lefs of both, the Vertuesof the feve- 
ral fweet Taftes can never be explained by the Chyrnical Princi- 
ples, and no new Virtues by them is difcovered^^ therefore all the 
advantage yve have obtained by thefe Chyrnical Diftillations is only' to ' 
fhew the nature of Sweetnefs in general,by difcovering the prijicinles 
contained in fweet Plants,and this is a greater advantage to Na rural 
Philofophy than toPhyfick, to which the tailing of Plants is more 
ufefiil. 
By the Tafte we diftingnifli the Sweets into their feveral Claffes, 
and we difcern tempers and digeftion, and mixture of their princi- 
ples^ and thence eafily guefs at their effefts in Animals^ :vnd by 
the Tafte w^e diftinguifti the different ftate of both the Oyl and 
Acid in Plants of different fweet Taftes ^ whereas the Chymiits 
obferve no difference cf the Tartar Acid, ivhether it be Acerb, or 
Vinous, or Volatile^ nor of the fw^eet Oyls from the bitter and 
Himy.
