ii2 EXPLANATION OF THE TABLES.

TABLE V.

¥N this table a view is given of the human crura cerebri and
cerebelli, of the tuber annulare, and medulla oblongata,
after diiTecting away from them the arachnoid coat and pia
mater, in order to mow the general direction of their medullary
fibres.

A A. BB. CC The anterior, middle, and posterior lobes of the brain,
slightly Iketched.
DD The hemispheres of the cerebellum.
EE The superior and anterior vermiform processes of the cerebellum.
FF The two optic nerves cut horizontally.
G The intimate intermixture of their medullary substance.
HH The optic nerves cut across near the foramina optica.
II Cineritious substances intimately connected to the optic nerves, and fur-
nishing some part of their medullary substance; between these there is
a fishire through which the pia mater and blood-vessels pass.
K A sec~tion of the infundibulum.
LL The corpora albicantia behind the infundibulum.
MM The crura cerebri consisting, on their surface, of bundles of medullary
fibres.
N A cineritious substance joining the crura cerebri and corpora albicantia
of opposite sides of the brain.
OO The principal crura cerebelli.
PP The tuber annulare, or pons Varolii, the surface of which consists of
medullary fibres laid chiessy in transverse bundles.
