CHASE. ETT. 
Of the SUBFECT or SEAT of Tatts. 
pa YA HE Third and Laff way of diftinguifhing Tufts, is 
G by their Subjeéf, or the Part or Parts where they 
\'e- are either wholly or chiefly perceived. And f, 
ID Tafts are either Fixed, or Movable. 
. Ne) a. §. A Fixed Taif, is that which keepeth 
po ) within the compaf$ of fome one Part, all the time 
BOG of its Durations as upon the Tip, or the Root of 
the Tongue, or other Part. 
3. §. A Movable Tafte, is either Diffufive or Tranfitive. 
4. §. A Diffifive Tafte, 1 call that, which by degree? {preads 
abroad into divers Parts, and yet in the mean time, adheres to that 
Part in which it is firft perceived. So the Bitterve/s in the dryed Roots 
of Black Hellebore, is firft felton the Tip of the Tongue; from whence 
it {preads it {elf to the midle of the fame. And the Bitterne(s of the 
Leavs of Wild Cucumer, {preads from the Tip, tothe Root of the 
Tongue. 
5. §. A Tranfitive Taffe, is that, which after fometime, wholly 
quitting the Part wherein it is firft perceived, is thence transfered into 
fome other Part : as the Bitterne/s of Gentian, imediately from the Tip, 
to the midle of the Tongue. And moft of the Diffufve, are alfo Tran- 
fitive. 
6, §. The feveral Parts which thefe ways become, and with fome 
latitude may be called, the Seats of Ta/ts, are, the Lips, Tongue, Pa- 
jate, Throat and Gulet. 
7. §. Uponthe Lips, the Root of white Hellebore, as alfo of Py- 
rethrum, being chewed, make a fenfible Impreffion ; which continues 
(like the fame of a Coal betwixt in and out) for 9 or 10 Minutes. 
But the Heat in other Parts much longer. 
8. §. Upon the Tongue, Tufts are perceived in Three places, as 
hath been intimated, On the Lip or Cone of the Tomgues as moft com- 
monly. Onor near the Bafis of the Toxgues where the Taffe of the 
Leavs of Wild Cucumer chiefly fixeth it fel, Or on the Vertex or midle 
of the Tongue; in which place it is obfervable, that the Taft of Gen- 
tian, Colocynthis, and divers other Bodies, is then confiderably ftrong, 
when not at all perceived at the Tip of the Tongve or in any other Part. 
9. §. Upon the Palate or Roofe of the Month, the Root, as I take 
it, of Deadly Night(bade maketh its chief Impreffion; and there con- 
tinues about four Mizutes in fome degree. 
to. §, The Throat, or the Uvala, Larinx and other adjacent Parts 
ate oftentimes the Seat of Taffe. Forthere are many Bodies, which 
although they have fearce any TaSfe upon the Toxgne, or any other of 
the aforefaid Parts, yet make a {trong Impreffion on the Throat: as the 
Leavs of little Duify, little Celandine, and of Pimpinel ; as alfo the 
Roots of Jalap, Mercury, Afparagus and others. Which being chewed 
makelittle or no Impreffion on the Tongue, but their Fuyce being {wal- 
% lowed,
