Sagittal section of the head of the new-born Elephant no. 1. f nat. size. The figure represents the catoptric
image of the right half of the head. The section is not exactly median: In the upper two thirds the cut has
gone somewhat to the right side, it is the right hemisphere which has been cut, and the medial surface of the
right hemisphere adheres to that half of the head, which has not been figured; most of the nasal septum has
also been taken away by the cut, which has further, as may be seen, grazed and sligthly damaged some of
the turbinal folds; it is also the organon Jacobsoni of the right side, which is seen in the figure. In the lower
parts, especially as regards the larynx and trachea, the cut has on the contrary gone to the left, nearly the
whole of the larynx and the trachea were on the half of Ihe head which is figured, but most of their left side
has afterwards been dissected off, so that their interior has been exposed.

As for what is not explained through the explanatory figure on this page we refer to the Explanation of
the Plate 19.
