Sagittal section of the head of the Elephant no. 2. Nearly I naL size. The section is not exactly median.
At the top the section goes somewhat to the left; the air-sinuses, which are here opened, belong to the left
nasal, maxillary and palatine bone, and the hemisphere which has been hit by the cut is the left; also at the
curvature of the nasal tubes it is the left tube which has been cut, and the section has here gone rather much
laterad, the nasal septum being here wholly on the other half of the head. But further downwards the section
has gone more to the right: the organon Jacobsoni, the longitudinal section of which is seen in the figure, is
that of the right side, and most of the nasal septum was also present in the figured half, but has afterwards
been dissected away with the exception of its caudal end (s). The cut has gone to the right of the pharyngeal
coecum figured in Plate 18 and 20. The trachea was also for the greater part wholly on the figured half, but
the right side has been dissected off. Only the anterior end of the oesophagus has been opened by the cut,
but this is principally the consequence of the oesophagus lying somewhat to the left of the median line.

The trunk has been cut through the left nasal tube, with the exception of the terminal end where the
section goes on the right side of the nasal septum.

p is the hard palate.
