;o OBSERVATIONS ON THE
CHAPTER XIX.
Of the Ganglia of the Nerves.
E
X Would begin herewith again observing an universal overfight os authors
~^ in their description of the ganglia of the spinal nerves. They describe
these as formed after the anterior and posterior fasciculi os nervous sibres
from the spinal marrow are united; so that every nervous fibre srom the
spinal marrow, is supposed to pass through a ganglion. Inftead os this, I
have observed, that the posterior fasciculus only of the spinal nerve enters
into the ganglion; and that authors had been deceived, by not having ssit
open the external coat of these nerves *.
One half, therefore, of all the nerves of the muscular organs os the trunk
of the body, and one half of the nerves of the arms and legs, do not pass
through ganglia.
S E C s. II.
Authors suppose that the olfa&ory, the optic nerves, the sourth, sixth,
seventh, eighth, with its accessory, and the ninth pair, are without ganglia.
But, as the sixth pair, portio dura os the seventh, the eighth and the
ninth pairs, are conneded by nervous silaments to the ganglia os the great
sympathetic nerve, we shall soon sind that there may be some reason sor sup-
poling that part os them likewise panes through these ganglia, as we cannot
pretend to judge os the course os the nerves srom observing the angles they
sorm with their trunks, the course os many nerves, being retrograde.
