ther different, as hath been faid. Secondly, from the moft apparent 
Diverfity of the Liquors or Saps, which they contain, and which, upon 
cutting the Branch tranfverfly, do diftinétly Bleed from them. Which 
is one way,whereby we do diltinguifh the Ve/fels of Avimals themfelves. 
Asin the Liver, it were hard to fay, which isa Blood-yefél, and which 
is a Bile-Veffel, where they are very fmall, if it were not for the Con- 
tents of them both. 
18. ¢. Thofe inthe Barque of Pine, are likewife of Two Kinds. 
The inmoft are Lymphedudts, asin the two former. The utmoft are 
not Milk-Veffels, but Gum-Vefféls, or Refiniferous; which ftand ftrag- 
ling, and fingly, about the midle of the Bargue. Out of thefe Vefels 
all the clear Turpentive, that drops from the Tree, doth iffue. 
19. §. Few, but very great. So that befides the difference of their 
Number and Pofition, and of the Liquors which they contain,and Bleed ; 
there is yet a Fourth, and that is, their Size. Mott of thefe Turpen- 
tine Veffels, being of fo wide a bore, as to be apparent to the naked Eye: 
and, through a good Gifs, above 34 of an Inch in Diametre. 
Whereas that of the Lymphedudés, can hardly be difcoveredby the beft 
Microfcope. 
20. ¢. The fame Turpentine Veffels of Pine, are likewife remarka- 
bly bigger, not only than the Lympheduéts, but many times, than the 
Milk-Vefels themfelves: as thofe of the F7g, which, in comparifon, are 
exceeding {mall every Arch, not being a fingle Veffel, but a Parcel or 
Clufter. of Veffels; Whereas one fingle Gum-Vefel in Pine, is fometimes 
as big as two whole Arched Clufiers, thats, as fome Scores of the Milk 
Veffelsin a Fig-tree. And the faid Gum-Peffels of Pixe, being compared 
with the Lympheduds of the fame Tree, one Gum-Veffel, by a mode- 
rate eftimate, may be reckoned three oe. hundred times wider than 
a Lymphedud. The like prodigious difference may be obferved in the 
Size of the feveral Kinds of Veffels of many other Plaxis. 
a1. §. THE Three next Quarters of Branches, are of Oak , Com- 
mon Sumach, and Common Wormwood. In the Barque-Veffels whereof, 
there is obfervable fome farther Variety. For in all or in moft of the 
above named, there are only Two Kinds of Feffels in the Barque. But 

“in Each of thefe, there are, at leaft, Three Kinds. 
22, g. And firft, in that of Ozk there are Lympheduéts, Rorife- 
vous, and a Sort of Refiwiferous. The inmoft or Lympheduéts, make a 
Radiated Ring, contiguous to the Wood. Theutmoft or the Rorife- 
rous make alfoa Ring, but not Radjated. ‘Thofe which are a fort of 
Rofin-Veffels, ftand in Round Parcels; the greater Parcels betwixt the 
Two Rings of Roréferous and Lymphedudts s and the leffer, betwixt 
the Roriferous the Skin. 
23. §. Thatthefé laft are different Vefels from both the other,feems 
evident, from the dificrence of their Pofition, as aforefaid. And that 
they are a fort of Refiziferous, is argued from hence; In that, not 
only Gals are very full of Rofiz, but that the Barque of Ozk it felf is 
alfo fomewhat Refimous. For the conveyance of whofe Reffzous parts, it 
is moft unlikely that any other Vefels fhould fubferve, but a peculiar 
Kind 3 which may therefore be properly called Refiziferous. 
24. §. Thenext is a Branch of Common Sumach. In the Barque 
whereof, there are likewife Three Kinds of Veffls. Firft ofall, there 
is athick Radiated Ring of Lympheducts , {tanding on the inner Aér- 
, gin
