Tongue 5 it hereby comes to país, that according as the taffable parts of 
any Plat are more or leß penetrant, fübtle, or difloluble, they are 
admitted into one part of the Tongue, and not another. And in the 
Throat, the outer Skin it flf, feems to be the immediate Senforys and 
fo, to be evidently affected with the Fuyces of fome Plants, from which 
gue recciveth little or no fenfible Impreffion.

it isalign, either that the Guffable Parts are le diffoluble ; or more 
fubtle, fo asto enter the Concaves of the Fibers and that there is an 
admixture of an Zereal Salt, or alike Sulphur; fome of the parts where- 
of, beingcrooked, hang like Hooks on the Fibers of the Tongue. For 
the reception of fuch a Taff, is not to be looked upon as a wound 
made witha Lancet, and fo the Lancet taken away 5 but withthe Lay.

Of the Judgment which may be made of the VIRTUES 
of Plants, from their Tafts. 
MES by duly obferving the Tafts of Plants, we may be 
J} direéted to underttand their Canfes. So alfo the 
Ufe and Virtues of thofe Plants or Parts of Plants 
in which they refide. For the proof whereof, an 
) Inftance might be fetched from every particular 
difference of Tai before fet down. But it may be 
RS, enough, to give thefe which follow, 
2. $. And firft, we may make no ill gueß ex 
Analogia, or where we find the fame Tast, that there the fame Virtue 
in fome kind, and in fome degree, may refide. So Jalap, Mercury, 
and Daify, have all of them that exafperating Tafi in the Throat be- 
fore deferibed 5 and they are all three more or lefs Cathartick. Where- 
fore, we may believe, that other Plants which make the like Im- 
c|jion on the Throat, and there are many others which do, that 
they are in fome degree alike Cathartick. Thofe Plants which 
are reckoned amongft the chiefeft cephalicks, caufe rather a du- 
rable, than a vehement Heat upon the Tongue, as Pyrethrum, Eu- 
Phorbinm, Black-Hellebore, Exc. It feemeth therefore reafonable to 
rank with thefe, any other Plant, though not ufed, which produceth 
the like durable Heat. The young Roots of Yarrom, or Miere
