me, the Circumference of it is between ieventeen and eicrhteen 
Inches. 
Thro’ the Middle of each Leaf lengthwife runs a ftrong Cojla 
or Rib, rifing above the Surface on both Sides, but mod on the 
lower or back Side. It decreafes in Thicknefs as it advances to- 
wards the Extremity, being thickefi: near the Branch to which it 
is fixed y and as during a fmall Space from thence the Leaf is ex- 
tremely narrow on both Sides, that Part has been taken for a Pe- 
dunculus or Foot Stalk j and in the Leaf I have here given the 
Dimenfions of it is about half an Inch in Leng-th. 
/ O 
From each Side of the Cofia arife a great many Fibres of dif- 
ferent Sizes, the largefl being parallel to one another, and inclin- 
ed obliquely towards the End of the Leaf. The others are fpread 
irregularly thro’ the Pulp of the Leaf which is pretty hard and 
folid, tho’ not very thick. 
The Surface and Edges of young Leaves are fiuooth and even, 
except where Rifings are form’d by the Coda and large Fibres j 
but as they increafe, the Edges become commonly pinched, the 
reft of the Leaf undulated or wav’d in many different Manners, 
bending likewile fometimes both according to the Length and ac- 
cording to the Breadth. 
The Leaves while frefh are all pretty much of the fame Colour, 
the upper Side being of a deep graffy green, the under Side 
lighter by a good many Degrees. 
Ffitherto we have confider’d the Leaves by themfelvesj the next 
Step is to examine them on the Plant. From the time that the 
Trunk appears above Ground, till the Branches are fhot our. 
Leaves grow upon it in the fame Order as the Branches do after- 
w\ards. In a young Plant only feven Inches high, I counted five 
Pair, befides the feminal ones, and the largeft of them was four 
Inches in Length. Thefe feminal Leaves differ from the reft in 
Shape, being more nearly circular, and adhering to the Stem by 
the Sides, rather than by one End. Some Leaves are found on 
the Trunk, even after the Branches are out, in all Ages of the 
Tree, and they grow always clofe by the Root of a Branch, but 
w ichout being pair’d as before. 
Two very tender Leaves are always found at the Top of the 
Trunk, join’d to a final! Ihort Foot Stalk, arifing from between 
the Pair immediately below them. This Foot Stalk increafes and 
becomes a new Joint or Internodium of the Trunk-, but before it 
has gain’d any confiderable Length or Strength, a new one tip’d 
with other two Leaves fhoots out from its Top, betwixt the two 
Leaves placed there. In this manner the Tree increafes in 
2 Height;
