Science; Natural history. 146 ELEPHANTS therium" by him, signifying "the beast of the Lake ; This creature is not bigger than a tapir, and had the shape of head and face which we see in that and the ordinary hoofed animals (Fig. 20). It had no trunk, and whilst it had six small and simplified mastodon-like grinders in each half of each jaw, it had six incisors in the upper jaw and a canine or corner tooth on each side. In. Fig. 19.—Restored model of the skull and lower jaw of the ancestra] elephant Palaeomastodon from the upper Eocene' strata of the Fayoum Desert, Egypt. It shows the six molar teeth of the upper and lower jaw (left side), the tusk-like upper incisors and the large chisel-like lower incisors in front. the lower jaw there were only two large incisors besides the cheek-teeth or grinders. Not the least interesting point about Meritherium is that it tells us which of the front upper teeth have become the huge tusks of the later elephants. Counting from the middle' line there are in Meritherium three incisors right and three left. The, second of these upper teeth on each side is much larger.
