The tusks are simply the incisor teeth of the upper jaw enormously developed and modified. Elephants of the present day are confined to the warm regions of the Eastern hemi- O sphere. They are seven to ten feet high, and ten to fifteen feet in length, and covered with thick, nearly naked skin. One distinctive characteristic of these animals is found in the grinders, the crown of which is deeply divided into transverse vertical plates, each con- sisting of dentine coated by enamel, and this by a bone- like substance which fills the spaces between the plates.
