38. g. The hollow of the Wood is filled up with the Pith, In 
the Circumference of which, ftands a Ring of Lymphedéus, of 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 obferved without a Microfcope : excepting the Bladders 
and number of Aer-Vefels, Yet Three things are hereunto neceflary 5 
viz. a good Eye, a clear Light, and a Rajfor, or very keen Kuife, 
wherewith tocut them witha fmooth furface, and fo, asnot to Diflo- 
cate the Parts. 
40, §. UPON Infpection alfo by the length, there are fome parti- 
culars, common, more or lefs, to moft Plats, yet better obfervable in 
fome, than in others. As firft, the Reticulation of the Veffels, (formerly 
deferibed ) not only in the Wood, but in the Barque : which is evident 
in a young Brauch ofCorin, upon the very Surface thereof; when fome 
of the Veféls begin to be caft off into the Skiz. And fo, by ftripping 
off the Si, upon the Surface of the Wood. 
ai. §. Incutting by the length, as well astranfverfly, the young 
Fibres, which grow within the Wood in the Edg of the Pith, are alfo 
feen. As likewife the manner of the Derivation of the Parts of the Bud 
fromthe Branch or Stalks asin Sonchus, There are alfo many Va- 
rieties in the P#th, fuch as thofe hereafter mentioned (2) which fall un- (4) Chap.4:

Of the Barque, as it appears through a good Microfcope: sd 
ee NOW proceed toa more particular Defeviption of 
feveral Trunks and Branches, as they appear through 
good Glaffes. 
i. §: Nowthe Irank, or Branch of every Tree, 
hath Three General Parts to be defcribed 5 fc. the 
Barque, the Wood, and the Pith. That likewife of 
every Herbaceous Plant, hath either the fame Three 
ree Parts Analogous; fe. the Cortical, the Lignons; 
and the pithy Parts. 
2. ¢ The Bargque confifteth of two Parts, fc. the outmoft or Skiz, 
and the Maiz Body, The Skizis generally compofed, in part, of very 
fall Veficles or Bladders, clufter'd together. That is, originally it 18 
fo; but as the Plant grows, the Skin dries, and the faid Bladders, do 
very much fhrink up and difappear. 
3. §. Amoneft thefe Bludders of the Skiw, there are ufually inter 
mixed a fort of Liguous Fibres, or Veffels, which run 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 sk# by means of the faid
