The American Buzzard.
The eye of tha American buzzard, according to a description given by a taxidermist, mast be a very unique arrangement In effect it is practically a3 good as an opora-gltfsa. The bird can screw it in or onfc, so to speak, and fit it to tha d!sfc:uie3 across which he wanfca to look at any object. The eyeball is surrounded by homey plates, which move siightly on both sides. The muscles a« the back of the eye are so arranged that they can thrust the centre of the" ball of the eye out in front, and the pressure of these homey plates keeps the whole eye from being pmhed out also. Thus the eye assumes a cone-like appearance from the outside. By relaxing this pressure and exerting these muscles in the opposite directiou the front of the eye can be made flat. By this means the buzzard can, while flying at a great height, sweep the ground with his telescopic eye in search of carrion, and as lie approaches the earth can keep adjusted his sight so that ho sees the desired object plainly, even when it is under his very beak. —The Optician.
