' " I ^ H I S table is intended to fliow the way in which the
branches of the different nerves of the face are connected.
FIG. I. Shows the way in whicli ii branch of the poi'tio dura of the feventh
pair of nerves is conneded with a branch of the infra orbitar branch
of the fifth pair in a man. The diameter of thefe nerves is reprcfented
three times greater than is natural.
A Is a branch of the portio dura.
B Is a branch of the infra orbitar nerve.
CDE Are principal branches fent off from the arch which the joining of
A and B forms.
C Is chiefly from A, but
D and E are evidently formed by branches of the portio dura A, joined
with branches of the infra orbitar nerve B.
FIG. II. Reprefents the joining of the fame nerves in the face of an ox,
F Is part of the mufcles of the upper lip.
G Is a branch of the portio dura.
HI Are two branches of the infra orbitar nerve, fent out at different holes
of the fuperior maxillary bone.
KLM Are three branches fent off from GHI.
K Is formed by a nerve from H joined to a nerve from 1.
L and M have each a thread from G, joined to a thread from N, which is
formed by H, joined with I. That is, the nerves L and M have threads
from tiie portio dura, and alfo from both branches of the infra orbitar nerve.
At O the portio dura and infra orbitar nerves were joined together by a
fmall nerve which formed an arch.
