through a magnifying glafs.
In all thefe FOUR Figures,
A B C D E Reprcfent nerves entering the ganglia.
F One of the nerves by which the thoracic ganglion is conneaed to the
proper intercoftal nerve.
GG In Fig. I. and III. arc the roots of the proper intercoftal nerves joined
to the ganglia by the bi'anches F F.
L In Fig. III. reprefents the out fide of the fore part of the cut ganglion.
H H H H Reprcfent the inner part of the ganglia, in which, with the magnifying
glafs, numberlefs fafciciili of fibres can be diftindly fcen, with

I In Fig. I. and II. a fmall ganglion, in which likewife nei'vous fibres can
be traced diftinilly.
At KK, Fig. II. and IV. where the nerve F connedls the ganglion to the
proper intercoftal nerve, fome of the nervous fibres of F are continued
with the nei-vous fafciculi in the upper part of the ganglion, and others
