Ears of Animals.
The hearing apparatus of animals is like that of human beings, but i modified to suit the conditions of the animal’s life. Deer, hares, and horses, like all animals whose life necessitates keen hearing, have ears shaped and set in the best way to catch faint for far-off sounds. The serpent has no ' ear-drums. The ear of the fish is a membraneous labyrinth connected with the bladder by a series of little bones. Though the sense of hearing is peri feet only in the higher animals, even j the animals that have no ears per- ■ ceive sounds. Instead of ears they are i supplied with fine nerves whose func- : tion is to note and to respond to every touch; nerves whose receiving | centers are different from the centers .of the purely tactile impressions. All animals, including insects, have an apparatus which enables them to distinguish the approach of an enemy.— Harper’s Weekly.
