I The medulla oblongata, a prolongation of the brain aftei the 
marrow-like substance of the cerebrum and cerebellum have 
united, and forming the commencement of the spinal marrow 
This portion has a ropy appearance. 
n. The point of the atlas bone which sustains or carries the 
first bone of the neck. 
o. The first bone of the neck. 
p. The dentata, or tooth-shaped bone, the second bone of the 
vertebral column. 
q . The cartilage covering the entrance into the eustachian tube, 
or communication between the mouth and internal part of 
the ear. 
r. The spinal marrow, extending through a canal in the centre 
of the bones of the neck, back, and loins, to the extremities 
of the tail, and from which the nerves of feeling and of 
motion which supply every part of the frame arise. 
s , s The septum-nasi ’, or cartilaginous division between the nostrils. 
When the nostril is opened, the membrane by which the 
cartilage and whole cavity of the nose is lined is seen. By 
the colour of this membrane, much more than by the lining 
of the eyelids, we may judge of the degree of fever, and 
especially of inflammation of the lungs or any of the air- 
passages. We also determine by the ulcerations which are 
seen on this membrane, the existence of glanders. This 
cavity on both sides is occupied by two bones, which, in 
consequence of being rolled up in the form of a turban, are 
called the turbinated bones. 
t, t The septum-nasi , cut off at the lower part to exhibit the 
spongy turbinated or turban-shaped bones, filling the cavity 
of the nostrils. Part of the cartilage is removed to display 
them. They are as thin as gauze, and, like it, perforated 
into a thousand holes. Between them are left sufficient 
passages for the air. 
If these gauze-like membranes were unrolled, they would 
present a very considerable surface. On every part of them 
there is spread the pulpy substance of the olfactory, or first 
pair of nerves, and are the organs of smell. The design of
