7- $. From thefe Annual younger Fibers it is, that although the 
Cortical Body and Pith are both,of the fame fubftantial nature, and 
their Pores little different ; yet whereas the Pith, which the firft year 
isgreen, and ofall the Parts the fulleft of sap, becomes afterwards 
white and dry : The Cortical Body, on the contrary, fo long as the 
Tree grows, ever keepeth green and moilt, Se becaufe the faid Sap.Fi- 
bers, annually grow therein, and fo communicate with it. 
8. $. The Pores likewife of the Lignous Body, many of them, 
in well-grown Timber, as in Oaken boards, are very confpicuous, 
in cutting both lengthwife and traverfe. They very feldom, if ever, 
run one into another, but keep, like fo many feveral Vefels, all along 
diftin&; as by cutting, and o following any one of them as far as 
you pleafe, fora Foot or half a Yard, or more together, may be ob- 
ferv’d. And fo, the like, in any Cane. N 
9. $. Befidesthefe, there are a leffer fort; which, by the help 
only of a good Speéfacle Glafs may be obferv’d. $ 
To. $. And thefe are all the Pores vifible without a Microfeope. 
The ufe of which, excepting in fome few particulars, I have pur- 
pofely omitted in this firft Book. Mr. Hook theweth us, befides thefe, 
a third, and yet finaller Sort; and (as a confirmation of what, in 
the Second Chapter, I have faid of the Pores of. the Lignous Body 
in general) that they are all continuous and prolonged by the length 
of the Trunk, asare the greater ones: whereof he maketh Experi- 
ment, by filling'up, in a piece of Char-coal, all the faid Pores with 
Mercury : which appears to paß quite through them, in that by a 
very good Glaf it 15 vifible in their Orifices at both ends; and with- 
out a Glafs, by the weight of the Coal alone, is alfo manifelt. All 
thefe I have feen, with the help of a good Microfcope, in feveral 
forts of Woods. As they all appeare in a piece of Oak, cut tranf- 
verfely, See Tab. 3. 
11. $. Upon further Enquiry, I likewif find, That the Pores 
of the Lignous Body in the Trunks of Herbs, which at firft I only fap- 
pofed, by the help of good Gaffes, are very fairly vifible: each Fi 
bre being fometimes perforated by 30, 50, 100, or hundreds of Pores. 
Or what I think is the trucft notion of them, That each Fibre, though 
it (eem to the bare eye to be but one, yet is, indeed, a great number 
of Fibres together 5 and every Pore,being not meerly a {pace betwixt 
the feveral parts of the Wood, but the Concave of a Fiber. So that 
if it beasked, what all that Part ofa Plant, either Herb or Tree, which 
is properly called the Woody-Part 3 what all that is, I fuppofe, That 
it is nothing elfe but a Clufler of innumerable and molt extraordinay 
finall' Vefels or Concave Fibers : as ina Slice of the Trunk of Bur- 
dock is apparent. 
12. $. Next the Infertions of the Cortical Body, which in the 
Trunk of a Tree fawd athawrt, are plainly difcerned as they run 
from the Circumference toward the Center; the whole Body of 
the Tree being vifibly compounded of two diftin& Subftanc e, that of 
the feveral Rings, and that of the Infertions, runni g.croís 5 fhewing 
that in fome refemblance in a Plain, which the Lives of Latitude and 
ofthe Meridian doin a Globe. The entrance of the Infertions into 
the Wood, is alfo, upon ftriping off the Barque, very apparent; as
