They are diftributed into twenty principal branches, 
the ten outermoft a little within the apple, are diverted 
from a freight line into fo many arches ; from which a 
few fmall branches are without any order difperfed thro* 
the apple; the five middlemoft and the five inmoft run in 
a ftrait line as far as the core, and are there diftributed 
•into as many leffer arches, the former at the outer and 
the latter at the inner angles of the core, upon which laffc 
the feeds hang. 
All thefe main branches meet together at the top of the 
apple, where originally they ran into the flower. 
A lemon hath a three-fold parenchyma, feemingly 
derived from each other; the texture upon every deriva¬ 
tion being fomewhat altered, by being made more clofe 
and elaborate. The outmoft called the rind, hath the 
moft open and coarfeft texture, being compofed of the 
largeft threads, and thefe wove up into larger bladders. 
Thofe little cells which contain the eftential oil of the 
fruit, and Hand near the furface of the rind, are fome of 
the fame bladders, but more dilated. 
From this outmofl parenchyma, nine or ten infertions 
are produced, betwixt as many portions of the pulpy part 
towards the center, where they all unite into one body, 
anfwerable to the pith in the trunk or root of the tree $ 
and are a confpicuous demonftration of the communica¬ 
tion between the bark and pith. 
Throughout this parenchyma the vefiels are difperfed, 
but the chief branches hand on the inner edge of the 
pith, juft at the extremities of every lamellae from thofe 
branches at the edge of the pith; other little and very 
fhort ones flioot into the pulp of the fruit, upon which 
the feeds are appendant. In the center of the pith are 
eight or nine in a ring, which run through the fruit up 
to the flower.
