nasal passage, and it is completed above by a pair of splints, the
nasals. Along the floor of the nasal passage, on the middle line, lies a
splint of bone formed by the coalescence of two halves. It embraces
in a V-like groove the mesethmoid (nasal septum) above, and lies on
the palate.
{Lines from First Edition only.}
-Its position is indicated by a heavy black line in 4, and it is
called, the vomer bone (vo.).-
{Lines from Second Edition only.}
[In the frog it is represented by two laterally situated bones.
This is the vomer bone (vo.).]
The nasal passages are partially blocked by foliated bony outgrowths,
from the inner aspect of their walls, which in life are covered with
mucous membrane, and increase the surface sensitive to smell. The
ethmoid ends in the ethmo-turbinal (e.t.); the nasal, the naso-turbinal
(n.t.); and the maxilla, the maxillo-turbinal (m.t.). In the anterior
corner of the orbit there is a bone, the lachrymal (lc. Figure 1), which
is hidden by the maxilla in the side view of the skull.
