In other words, the lens in far accommodation is a less convex, and in near accommodation a more convex lens. The single elastic substance takes the place of the series of different objectives in the microscope. The near limit of accommodation, for the normal or emme- tropic eye, is about 12 cm. ; the far limit is infinity. Infinity begins, however, at a distance of some 65 m. : since rays which reach the eye from a point at that distance may, for all practical purposes, be considered as parall...el. Questions. — (8) Draw a diagram, illustrating the mechanism of accommodation for far and near points. r (9) Assure yourself, by observation of Sanson's images (method to be indicated by Instructor), that the essential thing in accommodation is the bulging forward of the anterior surface of the lens!} 1^(10) Perform Scheiner's experiment (method to be indicated by Instructor). What light does it throw upon the problem of accommodation }\ Q (ir) Name some of the commonest and most disturbing im- perfections of cheap optical instruments.
