Show it eSae, Book IIL The Anatomy 106 Pith, {tand the 25. §. Hereunto adjacent, on the outer Edg of the hardly Lives; fhort l onee and Specks, in fome ls, Acr-Veffe diftinguithed, without a verynice Infpection. Sittinhin Thefe, are placedovher Lympheduds, Oppofite to thofe in the Barque. And within thefe Lympheduds, fill in the fame : radiated Line, run more of the Milk-Vefels. 27. §. AN EIGHTH, may be that of burdocks Wherein firft, there are a Sort of Lymphaduéts, which {tand in Arched Parcels, round ; the Trunk, adjacent to the Skin. 28. ¢. Within thefe, about the middle of the Barque, run the Milk-Vefels, in the form offmall round Specks. 29. §. Next to thefe on the inner Edg of the Barque are placed other Lymphadudts. Which, together with more of the fame in the Pith, and the Aer-Veffels betwixt them, {tand all in Radiated Lines, of feveral Lengths, and all fharpning towards the Centre. — 30. §, LET the Ninth, be that of Endive: In which there is al{o much curious Work. Next to the Ski, there is, firft, a thick and fimple Parenchyma. Then there isakind of Undulated Ring of Milk. Vefels. Within which ftanda Sort of Lympheduds, in feveral Parcels = fome, in Arched Half-Ovals 5 others, in fhort {lender Rays. Betwixt thefe Parcels, manyof the Mi/A-Veffels likewile ftand. 31. §. Next there is an wdulated Ring of other Lymphedués, par- 38. §. of Trunks. 107 The hollow of the Woodis filled up with the Pith. In the Circumference of which, ftands a Ring of Lympheddus, d€ the fame fort with thofe next to the Wood without. 39. §. All the Parts of thefe Trunks, may, as I have now de- feribed them,be obférved without a Microféope : excepting the Bladders and number of Aer-Veffels. Yet Three things are hereunto neceflary 5 viz. a good Bye, a clear Light, and a Rajor, or very keen Kuife, wherewith to cut them with a {mooth furface, and fo, asnot to Diflocate the Parts, 40. g§. UPON Injpection alfo by the length, there are fome parti- culars, common, more or lef, to moft Plawts, yet better obfervable in fome, than in others. As firft, the Reticulation ofthe Veffels, (formerly defiibed ) not onlyin the Wood, but in the Barque : whichis evident in a young Branch ofCorin, upon the very Surface thereof, when fome Tab. 19; of the Vefels begin to be caft off into the Skin. And fo, by {tripping off the Ski, upon the Surface of the Wood. 41. §. Incutting by the length, as well‘astranfverfly, the young Fibres, which grow within the Wood in the Edg of the Pith, arealfo feen. As likewife the manner of the Derivation of the Parts of the Bud fromthe Branch or Stalk; asin Sonchus. There are alfo many Varieties inthe Pith, fuch as thofe hereafter mentioned (4) which fall un- (4) Chap.4. der obfervation only in cutting by the length. ting as in moft Trunks, betwixt the Barque and the Pith, Within which, are the Aer-Veffels. And within Thefe, more Sap-Vefels. Both ofthem, in {mall Specks, anfwerable, or oppofite tothe Rays in the Bargue. 32. §. I SHALL give alfo one or two Examples of Trees, or Arborefeent Plants ; the Vine and Common Sumach. Ina Slice ofthe former cut tranfverfly, next the Ski”, thereisa Thin Barge. In the in- ner part whereof, adjacent to the Wood, ftand the Lymphedutts in {everal Half-Oval Parcels, oppofite to fo many Radiated Pieces of the Wood. 33. §. The Wood is divided into the faid Pieces, byas many Parenchymous Rays,inferted from the Bargue, and fo continuous therewith. 34. g. Within thefe Radiated Pieces of Wood, tand theAer-Ve/- fels 5 the Jargeft of which, efpecially if held up againft the light, are plainlyvifible to the bare Eye. : ahi 35. §. Within the hollow ofthe Wood, ftands the Pith ; in the young Growths always large. In the utmoft Verge whereof, adjacent to the Wood, ftand a few more Sap-Veffels of the fame Sort with thofe in the Barque. 26. §. INAlike Slice of Common Sumach, contiguous to the hairy Shiv, there is a Ring of Lymphednéfs. Next to thisa Simple Parezchyma. Thenfeveral Arched Parcels of Lymphedu@s. Within thefe, a Ring of Milk-Veffels. And thena Rig of other Lympheduéts. Thus far the Barque. 37. §. Within the Bargue, ftands the Wood, divided into feveral Portions, by the Diametral Infertions divided from the Bargue. In the Body of the Wood, ftand the Aer-Vefels, very much {maller than in the Vine. CHAP. I, Of the Barque, as it appears through a good Microfcope. ZB NOWproceed toa moreparticular Defeription of feveral Trunks and Branches, as they appear through good Glaffes. 1. §. Now the Trunk, or Branch of every Tree, hath Three General Parts to be defcribed; /é. the Z, Darque, the Wood, and the Pith. Thatlikewife of OLE every Herbaceous Plant, hath either the fame Three Parts 5 or elfe Three Parts Analogous; c. the Cortical, the Lignons, and the Pithy Parts. age Tt arque confilteth of two Parts, /c. the outmoft or skin, and the Main Body. The skinis generally compofed, in part, of very {mall Veficles or Bladders, clufter’d together. That is, originallyit is fo; but as the #/amt grows, the Skin dries, and the faid Bladders; do very much fhrink up anddifappear. 3. §. Amongft thefe Bladders of the Skin, there are ufually intermixed a fort of Lignous Fibres, or Veffels, which tun through the length Tb, 20: of the Skin 5 asin Mallow, Nettle, Borage, Thiftle,and moft Herbs. Which is argued not only from the Toughnefs of the shiz by meansof the faid Veffels 5 but in fome Plants,maybeplainly feen, as in Teafle. In which, U2 the |
