r, 2, 3,4, 5, 6 , 7. arc Capillary Veflels, which run 
longitudinally through the Branch, in the Ligneous 
part, which was made in the Year 1715*. Through 
thefe Tubes, the Steam rifech from the Root ; the ftrength 
of which is well explain’d by the Engine for railing 
Water by Fire, invented by the late Captain Savory. 
From A to B, we may view Veflels of the fame 
fort, made at the fame time. 
8, 9. are Veflels of the fame ufe with the former, 
now forming themfelves for the ufe of the Year 1716. 
By this means the Diameter of the Branch is increas’d, 
and additional Nourilhment fuflerd to pafs into thofe 
Buds which are to make new Branches. Thefe are made 
out of the Fourth or innermoft Bark, markt C, C. 
The Mouths of the Capillary Tubes of the Y'ears 
1715", and 1716. are D, E. The Vapour which rifeth 
from the Root, is continued in thefe Veflels, to- the ex- 
tremities of the Branches ; where it meets with parts (not 
here defcrib’d) like to Glands ; which Glands, if we may 
fo call them, are likewife found at every Knot or Joynt. . 
At thefe places, the Vapour coming near the Airiscon- 
denfed, and returns between the Barks, by means of its , 
own weigjit, down F, G, H, leaving in each Bark mark’d 
I, K, L, fuch Juices as each of them naturally is inclin’d to 
feparate.from it 5 till at lafl, the more Oyly part palling 
to the Root, may lengthen the Fibres thereof, as Icicles 
are lengthned ; and by its Oleous Particles, preferve 
them from Rotting by the Wet. The parts which com- 
pote the teveral Barks, are P arenchymeus or Spongey. 
The firft mark’d M, is of a clofer Texture than the 
fecond N, and the fecond clofer than the third O, and 
fo on till- thefe Parenchymous Parts- are interwoven 
with the longitudinal Wood-VefTels, where they are 
fomewhac conftrain’d, till they come to make the. Pith * 
mark’d P, Then they are much Larger than in any 
othex. i
