ther different, as hath been faid. Secondly, from the moft apparent 
Diverfity of the Liquors or Saps, which they contain, and whicb,upon 
cutting the Branch tranfverfly, do diftin&ly Bleed from them. Which 
is one way,whereby we do diltinguifh the Fe/ßls of Animals them(elves. 
Asin the Liver, it were hard to fay, which is a Blood-Yeffel, 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 Lympheduöfs, asin the two former. The utmoft are 
not Atilk-Veffls, but Gum-Vefils, or Refiniferons s which ftand thrag- 
ling, and fingly, about the midle of the Barque. Out of thele Vefels 
all the clear Turpentine, that drops from the Tree, doth iffue. 
19. $. Few, butvery great. So that befides the difference of their 
Number and a file and of the Liquors which they contain,and Bleed 5 
there is yet a Fourth, and that is, their Size. Moft of thefè Turpen- 
tine Vefels, being of fo wide a bore, as to be apparent to the naked Ey 
and, through a good Glafr, above $4 of an Inch in Diamen 
Whereas that of the Lympheduéfs, can hardly be difcoveredby the bef 
Microfcope. 
20. $. The fame Turpentine Vefels of Pine, are likewife remarka- 
bly bigger, not only than the Lymphedu&s, but many times, than the 
Milk Vefels themíelves : as thofe of the Fig, which, in comparifon, are 
exceeding fmall 5 every Arch, not being a Single Veffel, but a Parcel or 
Chifter of Vefels 3 Whereas one fingle Guni-Veffel in Pine, is fometimes 
as big as two whole Arched Clufters, that is, as fome Scores of the Milk 
Veffelsin a Fig-tree. And the faid Gum-Peffelsof Pine, being compared 
with the Lympheduéls of the fame Tree, one Gum-Veffel, by a mode- 
rate eftimate, may be reckoned three ot ae hundred times wider than 
a Lymphaduét. The like prodigious difference may be obferved in the 
Size of the feveral Kinds of Veffels of many other Plants. 
21. $. 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 Veffels in the Barque. But 
in Each of thefe, there are, at leat, Three Kinds. 
22. 5. And firft, in that of Oak there are Lymphedutts, Rorife- 
rous, and a Sort of Refmiferons. The inmoft or Lympheduéts, make a 
Radiated Ring, contiguous to the Wood. The utmoft or the Rorife- 
rons makealfo a Ring, but not Radiated. Thofe which are a fort of 
Rofin-Veffels, ftand in Round Parcels ; the greater Parcels betwixt the 
Two Rings of Roriferous and Lympheduöfs; and the lefler, betwixt 
the Roriferous and the Skin. 
23. $. Thatthefe laft are different Yeffels from both the other,{eems 
evident, from the difference of their Pofition, as aforcfaid. And that 
they are a fort of Refimiferons, is argued from hence; In that, not 
only Gulls are very fall of Rofi», but that the Barque of Oak it felf is 
alfo fomewhat Refímons. For the conveyance of whole Refizous parts, it 
is moft unlikely that any other Feje/s thould fubferve, but a peculiar 
Kind 5 which may therefore be properly called Refiniferons. 
24. $. The next is a Branch of Common Sumach. In the Bargue 
whereof, there are likewife Three Kinds of Vefls.  Firlt of 
isa thick Radiated Ring of Lympheduds ; ftandıng on the int
