Intelligence of Elephants

This book deals with the intelligence of the elephants, their emotions and memory. The higher mental faculties of the elephant are more advanced in their development than in any other animal, except the dog and monkey... "The elephant is the largest living land animal. Though numerous forms existed in early geological times, it is represented today by two species only: the African elephant, and the Asiatic elephant.
The African elephant differs from its Asiatic cousin in several particulars. The apparent distinguishing features are the tusks that attain a much greater development and occur in both sexes, while in the Asiatic species the males alone possess them. The African elephant is at least a foot higher than the Asiatic, attaining a maximum height of eleven feet. Its ears are extremely large, covering the shoulder, and in some instances measuring three and a half feet in length by two and a half feet in width, while those of its Indian relative are comparatively small."...
