284 The Diverfties Lea. VI. 
Cre Astley Ides: 
Of the SUBJECT or SEAT of Tatts. 
2 22 HE Third and Laft way of diftinguilhing Tafi, is 
@ by their Subjecf, or the Part or Parts where they 
GS 
7 
i E are either wholly or chiefly perceived, And (o, 
ES T ME Tafis are either Fixed, or Movable, 
mE 
O 2.6. A Fixed Tast, is that which keepeth 
within the compas of fome one Part, all the time 
ofits Duration; as upon the Tip, or the Root of 
the Tongue, or other Part. wi 
3. $. A Movable Taft, is either Diffufive or Tranfitive, ib 
we Tafte, Y call that, which by degrees fpreads © 
abroad into divers Parts, and yet in the mean time, adheres to that hei 
Part in which it is firft perceived. So the Bitierzefs in the dryed Roots 
of Black Hellebore, is firft felton the Tip of the Tongue; from whence 
it (preads it felf to the midle of the fame. And the Bitterneß of the 
Leavs of Wild Cucnmer, {preads from the Tip, to the Root of the 
Tongue. 
5. §. A Tranfitive Tufte, is that, which after fometime, wholly 
quitting the Parf wherein it is firft perceived, is thence transfered into 
fome other Part : as the Bitternefs of Gentian, imediately from the Tip, 
to the midle of the Tongue. And moft of the Diffufive, are alfo Tran- 
fitive. 
` 6, $. The feveral Parts which thefe ways become, and with fome = 
latitude may be called, the Seats of Tafts, are, the Lips, Tongue, Pa- zum: 
date, Throat and Gulet. z 
7. $. Upon the Lips, the Root of white Hellebore, as alfo of Py- J 
retkrum, being chewed, make a fenfible Imprejlion; which continues 
(like the flame of a Coal betwixt in and out) for 9 or 10 Minutes. 
But the Heat in other Parts much longer. 
8. $. Upon the Tongue, Tafts are perceived in Three places, as 
hath been intimated, On the Tip or Cone of the Tongue; as molt com- 
monly. Onor near the Bafis of the Tongue, where the Tufte of the 
Leavs of Wild Cucumer chiefly fixeth it fel. Or on the Fertex or midle 
of the Tongues in which place it is obfervable, that the Ta/t of Gen- te 
tian, Colocynthis, and divers other Bodies, is then confiderably ftrong, > 
when not at all perceived at the Tip of the Tongue or in any other Part, 
9. $. Upon the palate or Roofe of the Month, the Root, as I take 
it, of Deadly Nightfhade maketh its chief Imprejions and there con- 
tinues about four Minutes in fome degree. 
10. $. The Throat, or the Vonla, Larivx and other adjacent Parts 
oftentimes the Seat of Taffe. For there are many Bodies, which 
although they have farce any Tasfe upon the Tongue; or any other of 
forefaid Parts, yet make a {trong Impreffion on the Throat: as the 
«os of little Daily, little Celandine, and of Pimpin alfo the 
Roots of Jalap, Mercury, Ajparagus and others. Wh 
makelittle or no Imprelfion on the Tongue, but the 
ce being fwal- 
lowed,
