23. $. THE sap-Veffls, are not only of divers Kinds, in divers 
Roots, but in the fame. Whether in all, I doubt : but in fome it is 
certain they are: For if you cut a Fenil-Root traveríe, both Milk and 
Limpid Sap, will prefently afcend, and, upon accurate infpettion , 
appear thereupon dinftinétly. So the Roots, both of Trachelinm and 
Enula, Bleed both a Lympha, and a Citrine Balfame: and Wormwood, 
both a Lympha, and a Terebinth, at the fame time. So alfo the Root 
of Dandelion being cut in November, feems to bleed both a milk, 
and a Lympha; the latter being drowned by the former at another 
time when it is more copious. Whether all Roots have Lympheduits, 
is doubtful 5 but ‘tis moft probable, that they have, more or fewer 5 
ftanding, for the moft part, in a Ring, at the Inner Verge of the 
Barque : the Sap whereof, I fuppofe, is fo far of common Nature in 
all Roots, as to be Clear, and leß Oily. 
24. $. THE Quantity of thefe Vefels is very different: In Borage, 
Peony, Biftort, but few 5 in Afparagus, fewer : in Parfuep, Celendine, 
many; in Fenil, Marfh-mallow, many more: and betwixt thefe ex- 
treams, there are many Degrees, as by comparing the Roots of Horfe- 
Radifh, Turnep, Briony, Skirrets, Parfley, Goats-Beard, and as many 
more as you pleafe, maybe feen. Amongft the feveral Sorts of Docks, 
they feem in Patience, to be the fewelt; in Red-Dock, the molt nu- 
merous. There are two ways of judging of their Number 5 Either 
as their Extremeties are vifible upon the traverfe cut of the Barque 5 
or as the Barque is diverfly Brittle or Tough 5: being fo, from the va- 
rious Number of thefe Vefels therein, as in the Second Chapter hath 
been faid. 
25. $. The Quantity of the afcending Sap, is a doubtful argu- 
ment, whether of the Number, or Size: of thefe Vefels. For it is 
common to moft Milky-Roots, for the Milk to afcend more copioufly : 
yet in fome of them, the Vefels feem, in proportion with the Paren- 
chymous Part, not to be fò numerous, as in fome other. Roots, where 
the afcending Sup is les as by comparing the Laöfeals of Dandelion, 
and the Lymphaduéts of Fenil together, may appear: fo that it fhould 
fem, that the bore of the Laéeal Veffels; is greater than that of the 
Lymphaduds. 
Barque, as of Melilot. In others, they {tand not fo much in Prieks, 
as Portions or Colums, as in Cunnfiy-
