gin of the Barque, contiguous with the Wood. Thefe Veffels exhibit 
their Lympha very apparently. A fecond kind of Pefels, fe. Rori erons, 
are fituate towards the outer Margin of the Barque, and are compofed 
into diftin&® Arched Parcels, all ftanding in a Ring. 
25. § Betwixt thele Two Kinds ftand the Milk-Veffels. Every 
fingle Milk Veffél being empaled or hemmed in with an Arch of Rorife= 
rous. The Aılk-Veffels are extraordinary large, almoft as the Guns 
Veféls oF Pine 3 fo as diltinĝly to be obferved without a Microfeopes 
after they are evacuated of their Milk 5 and without diffculty will 
admit a Virginal Wyer 5 being two or three hundred times as big asa 
Lymphedutt. Befides thefe Three forts of Vefels, there is alfo a Ring, 
adjacent to the Skins which feemstobe another fort of Roriferous. 
26. § The Laft, is a Branch of Common Wormwood. In the Tab.35s 
Barque whereof, there are likewife Three Kinds of Veffels. Firft of 
all, there is a thin Radiated Ring of Lympheduis, contiguous with the 
Wood or on the inner Margin of the Barque. Yet the Ring is not en- 
tire, but made up of feveral Parcels 5 which are intercepted by as ma- 
ny Parenchymous inferted into the Pith. 
27. $: A Second Sort of Vefels, which feem to be Roriferovs, are 
fituate about the middle of the Barque: and are compofed into Arched 
Parcels, which likewife ftand all even in a Ring. 
rifon, are 28. $. Beyond thefe Arches, and towards the outer Margin of the 
Parcel or Barque, ftand a Third Sort of Veffels. Different from the Milk-Vep: 
metimes Jels in Sumach, both as to their Situation, Size and Content. For in 
the Milk Sumach,the Milk-Vefels fand within the Arched Lympheduéts : whereas 
ompared thefe in Wormwood, ftand without them. Likewife, being the Yepels 
a modé ofan Herb, they are far lef 5 fè. about the compaß or width ofa {mall 
der than Wheat-stram. Their Content, is not a Milk, buta liquid, moft Oleous 
dnde and v:/tid Gum. Or which, for its pleafant Flavour may be called an 
Aromatick Balfom, For it perfectly giveth whatever is in the Smell 
k, Come and Tufte of Wormwood : being the Effence of the whole Plant, which 
lero nature treafüreth up in thefe Veffels. So that they are, in all refpects, 
tof ihe analogous to the Turpentine Veffels in Pine. There are divers other 
Herbs and Trees, which in the like Veffels, contain a Turpentine, or ra- 
ther Aromatical Balfom 3 as Angelica, Helenium and others ; the Veffels 
being fo very large, that they may be eafily traced with a knife, in cut- 
ting by the length ofa Branch or salth, 
29. $. Whether in fome Plants, there arenot more Sorts of Vef- 
fils, in the Bargue, than have been now mentioned, I cannot fay: 
Though we have not much reafon to doubt ofit. Becaufe we fee; 
there is fo great variety in the Viftera of Animals. For what the 
Vifeera are in Animals the Veffels themfelves are in Plants, 
30. $. CONCERNING the Form and Texture of the Lympheduéts, 
there are fome things, which though they are belt obferved in the 
Wood, yet in regard I am now deferibing the faid Vefels, I (hall here 
therefore add. T have already faid, and thewed, in the former Books, 
That the Lignous and Towy Parts of all Plants, are Tubulary. And 
that the Lympha is conveyed, by the length of a Plant, through an in- 
numerable company of fmall Tubes or Pipes. 
31. $. The Queftion may be yet further put: If the Tomy Parts of 
the Barque are made of Tubes, What are thefe Tubes themfelves made 
up of? I anfiver, That thefe Tubes or Lymphaduds, are not only 
themfelves 
rque. But
