It is a soientific truth, though not widely known, that to preserve all the powers of the eye to a good oíd age, the eye should always be rubbed toward the nose ; never f rom the mose outward. The natural direction for passing the fingers over the eyes, especially when washing the face, is the one most destructivo to the eyesight ; so that unless one fixes the fact firmly in mind and becomes familiar with the motion, he will surely injure his eyes. The explanation is that in rubbing the oyo from the nose outward the tendenoy is to flatten the ball of the eye, and aa the cornfa or front part of the eye becomes flattened the rays of light which enter the eye are not sufficiently refracted to bring them to a focus on the retina. The focus falling behind the retina, the sight is diuitned or blurred ; while it' the eye be rubbed towards the nose one rubs more upon the side of the eye-ball and so helps nature to preservo the original conical shape of the cornea or eye-front. When the eye is flattened the object to be viewed has to be removed farther from the eye, so that the refraction produoed may be sufficient to bring the rayg of light to a focus on the retina. Henee the long-sightodness of oíd age is due wholly to the flattening of the cofnea of the eye, and if not wholly obviated, may be greatly relieved, by this effectual and simple method of rubbing the eyes towards the nose. They teil a queer story about the doctors ia a certain Texas town, who all went last sunimer to attend a medical convention. They were absent about two months, and on their return found all their patients had recovered, the drug stores had closed, the nurses opened dancing-schools, the cemetery was cut up into building lots, the undertakers had gone to making fiddles, and the hearse had been painted and gold for a circus wagon. A Scotchman went to a lawyer once for advico and detailed the circumstances of the case. " Hare you told me the facts precisely as they occurred ?" asked the lawyer. "O ! aye, eir !" replied he ; "I teil ye the plain truth. Y can put the lies into it yourstlf !
