EXPLANATION

OF

PLATE 38.

ca

ca

Fig. 1. Part of the right half of the head
of the old Elephant "Chang"; only the right
nasal cavity has been drawn in detail. The
nasal septum has been cut away, only the caudal
(inferior) end of it having been left. The
mucous membrane of the cartilaginous and
bony parts of the nasoturbinal and of the nasal
cartilage has been dissected off; the anterior
end of the nasal cartilage has been cut off.
/) bony part of the nasoturbinal; ca moveable
cartilaginous plate of the same; ca' anterior end
of the cartilaginous part of the nasoturbinal,
being continuous with the cartilaginous septum,
which is here cut away; et ethmoturbinals; i inferior
part of nasoturbinal consisting only of
soft tissues; nc nasal cartilage; r margin of
vomer; s caudal end of nasal septum consisting
here onlv of soft tissues; do vomer.

Fig. 2. The same, further dissected. The cartilaginous plate ca has
been cut across and the posterior part of it bent up and fixed by means
of an anatomical hook, so that the room below it and the opening into
the nasal sinus are seen; a sound (the upper sound in the figure) has been
introduced through this opening into the nasal sinus, which has been shaded,
while the other air-sinuses are onlv indicated in outline. Another sound
has been introduced below the caudal end of the nasoturbinal into the
opening of the maxillary sinus (comp. fig. 8—9 on Plate 36), from which
the inferior end of the sound protrudes. Of the endoturbinalia the margin
has been cut off, so that some of the ectoturbinalia are seen. The specimen
is seen somewhat more from behind than in fig. 1, so that the nasal tube
is shortened, in comparison with fig. 1. //—VII basal laminae of endotur-
binals.

Fig. 3. The same, still further dissected. The whole of the nasoturbinal, the bony as well as the cartilaginous
parts, have been cut off, so that the large diverticulum is seen; on the lateral wall of this latter are
seen the opening of the nasal sinus and the groove in the intermaxillary bone. The ecto- and endoturbinalia
have been taken away, only the bases of them having been left (comp. the textfigure).

The brownish parts in these figures are those where the mucous membrane of the nasal cavity is still present.
