This is done in the eye by an application offibres, i. e., of contractile strings, similar in their position andaction to what an artist would endeavor to procure, and mustemploy if he had the same piece of workmanship to perform.II.

Now this, according to the principles ofoptics, that is, according to the laws by which the transmis-sion of light is regulated (and these laws are fixed), could notbe done without the organ itself undergoing an alteration, and receiving an adjustment, that might correspond with the 70 THE EYE exigency of the ease, that is to say, with the different inclina-tion to one another under which the rays of light reached it.Eays issuing from points placed at a small distance from theeye, and which consequently must enter the eye in a spread-ing or diverging order, cannot, by the same optical instru-ment in the same state, be brought to a point, i. e., b
