Musical Ear.

Notes differing only one-hundredth part of a tone from each other can be distinguished by Aie well-trained ear of a musician. Most people cannot perceive a difference of one-tenth of a tone, and a few can scarcely tell one tone from another. The cause of this curious disparity is due to slight differences in the structure of the cochlea, a wonderful piece of apparatus In the innermost part of the ear. says London Tit-Bits. It is a little body, shaped like a snail shell, and believed to be the part of the hearing apparatus which recognizes musical sounds. In Its structure it close ly resembles the Strings of a piano and even has a damper to prevent the mixture of sounds quickly following one another. « This little musical apparatus is set going by vibrations received from the middle ear or drum and in gome mysterious manner it sends these on to the brain through the auditory nerve in the form of musical sounds.
