fiitch'd up (though in divers manners ) together. And even all thofe 
Parts ofa Plant, which are neither formed into vifible Tubes, nor in= 
to Bladders, are yet made up of Fibers. Which, though it be difficul 
to obferve, in any of thofe Parts which are clofer wrought and prin- 
cipally in the Infértions of fome Trees : yet in the Pith,efpecially of fome 
Plants, which confifteth of more open work, they are more vifible. 
Which introduceth the obfervation of them in all other Parenchymons 
Parts. Soin the Pith of a Bulrufh of the Common Thistle, and fome 
other Plazts; not only the Threds of which the Bladders; but alfothe 
fingle Fibres, of which the Threds are compofed 5 may fometimes with 
the help of a good Giaft, be diftinétly feen. Yet one of thefe Fibres, 
may reafonably be computed to be a Thoufand times fmaller than an 
Hor fe- Hair. 
12. §. The Fibrofity of the Parenchyma is alfo vifible in fome Woods, 
in which, it isapparently mixed with the Ligvous Parts, not only by 
Infertions, but per minimas Partes organicas. That isto fay, The Parex- 
chymous Fibres, like {maller Threds, are either wraped round about both 
the Ligwous and the Aer-Vefels, or at leat interwoven with them, and 
with every Fiber of every Yeffél: as in very white Ah or Fir-Wood, Th, 39. 
with an advantagious pofture and light, may be obferved, 
13. § WHENCE it follows, that the whole subffance, or all 
the Parts of a Plant, fo far as Organical, they alfo confift of Fébres, 
OF all which Fibres thofe of the Lywpheduifs, ran only by the 
Length of the Plant : thofe of the Pith, Infértions, and Parenchyma 
of the Barque, run by the breadth or horizontally : thofe of the Aer- 
Veffels, fetch their Circuit by the Breadth, and continue it by the 
Length. 
14. §. By which means, the faid Parenchymous Fibres, in fetch- 
ing their horizontal Gircles, do thus weave, and make up the Bladders 
of the Pith, in Opex-Work, And the fame Fibres being thence conti- 
nued 3 they alfo weave and make up the Infertions, but in Clofe-Work, 
Betwixt which Infértions, the Vefels being likewife tran{verfly inter- 
jected, fome of the fame Fibres wrap themflves alfo about thefé; thus 
tyivg many of them together, and fo making thofe feveral Conjugati- 
ons and Braces of the Vefféls, which I have formerly defcribed. And 
as fome of thefe Horizontal Fibres ave wraped about the Veffels 5 fo alfo 
about the Fibres, whereof the Veffels are compofed. By which 
micans it is, that all the Fébres of the Vefels are Tacked or Stitched Tah, 463 
up clofe together into One Coherent Piece. Much after the fame 
manner, as the Perpendicular Splinters or Twigs of a Basket, are, by 
thofe that run inand out Horizontally. And the fame Horizontal Fi- 
bres, being ftill further produced into the Barque; they there com- 
pofe the fame work over again (only not fo open ) as inthe Pith, 
15. § SO THAT themoft unfeigned and proper refemblance 
we can at prefent, make of the whole Body of a Plant, is, Toa piece 
of fine Bone-Lace, whenthe Women are working it upon the Cyfhiox, 
For the Pith, Infertions, and Parenchyma ofthe Bargue, are all extream 
Fine and Perfe@t Lace-Work: the Fibres of the Pith running Horz- 
zontally, as do the Threds in a Piece of Lace 3 and bounding the {e- 
veral Bladders of the Pith and Barque, as the Threds do the feveral 
Holes of the Lace; and making up the Infertions without Bladders, or 
with very {mall ones, as the fame Threds likewife do the clofe Parts of
