EXPLANATION
OF
PLATE 22.
On this plate and the following are represented a series of skulls of Indian Elephants of various age, fig. 1
being the youngest, the others successively older, in order to show certain differences of the skulls according
to age. The skulls are all seen from above in the same position. While fig. 1 is a little magnified, the others
are all somewhat or much reduced in size (the real sizes are stated p. 85—87).
