4. §. In fome Plants, they are Equidiftant 5 in others, not: in 
fome, the Great ones are Equidiftant; in others, the Leffler 5 in others, 
both’; in fome, neither. Which Varieties are not accidental; but con- 
ftant to the species in which they are feverally found. 
5. §. - They are not always vifibly continued from the Circumfe- 
rence to the Centre of the Wood: but in fome Branches, as of Sumach 5 
and in moft Truwks of many years growth, declining, in fome places, 
under or over, froma Level, are thereby, upona Tran{verfe Section, 
in part cut away. 
6. §, They have yet one more Diverfity, which is, That in di- 
vers of the aforefaid Branches, they run not only through the Wood ; 
but alfo fhoot out beyond it, into fome Part of the Barque, as in 
Ela, Sumach, Wormwood, &c. Whereas in Pine, and fome of the 
reft they either keep not diftin& from the other parts of the Parenchy- 
ma of the Barque; or are fo fall, as not to be diftinguifhed there 
form. 
7. §. The Texture likewife of thefe Infertions is fomewhat various. 
For in Wormwood, and moft Herbs, they are manifeftly compofed of 
{mall Bladders : differing in nothing from thofé of the Barque or Pith, 
faving, in their being much lef. Yet in Herbs, they are much larger 
than they are in Trees. And in many Trees, as Apple, Pear, Plum, Pine, 
&c. they are either quite loft, or fo {queezed and preffed together 
by the hard Wood ftanding on both fides, as to be almoft undifcernable. 
8. §. So that although the Parenchyma of the Barque or Pith, and 
the Infertions in the Wood,are of the fame Specifick Nature or Subftance : 
yet there is this difference betwixt them ; That the Fibres of the for- 
mer, are fo Netted together, as to leave feveral round Vacuities 3 or 
to make a great many little Bladders, whereas, in the latter, they are 
ufually fo far crowded up, as to run (as when a Net is {tretched out ) 
like a Shei of Parallel Threds. 
9. §. Ofthefe Infertions in the Wood, it is futher obfervable, That 
they do not only run betwixt the Ligwows Portions; but that many of 
their Fébres are likewife all along diftributed to the feveral Fibres, of 
which the Lignous Portions confift,and are interwoven with them; both 
together thus making a piece of Linfj-Woolfy Work, or like many other 
Manufadures in which the Warp and the Woof are of different Sorts 
of Stuff: as in the end of the Fourth Chapter is further explained. 
to, §. ‘THE WOOD is likewife compounded of Two Sorts of. 
Bodies 5 That which is ftriétly Woody 4 and the Aer-Vefels. mixed here- 
with. The true Wood is nothing elfe but a mafs of antiquated Lyw- 
pheduds, viz. thofe which were originally placed on the inner Mar- 
gin of the Bargue. For in that place, there grows, every year, anew 
Ring of Lymphaduéts. Which lofing its original foftnefs by degrees, 
at the latter end ofthe year, isturned into a dry and hard Ring of 
perfect Wood. 
11. §. So that every year, the Barque of a Tree is divided into 
Two Parts, and diftributed two contrary ways. The outer Part falleth 
off towards the Shiv 5 and at length becomes the Shi it fel In like 
manner, ashath been obferved of the Skiz cfthe Root. Or asthe Cz- 
ticulain Animals, is but the efflorefcence of the Cutis. I fay, that the 
elder Skzz of a Tree, is not originally made a Skiz3 but was once, 
fome of the widle part of the Bargue it felf, whichis annually caft orf, 
and
