This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1899 edition. Excerpt: ...forgetting that the lines of vision--i. e., the axes--of the two eyes cross as they pass outward. See Fig. 4, page 22. The eyes rotate thus, not only when moving apart to look fixedly at the scene in front, but when, moving in the same direction, both are glancing from side to side of this scene. But now, when the eyes rotate, what must be the effect? What but to cause each eye to roll not only sideward but also downward? And when this has been done what should we expect but--to describe the result more graphically than scientifically--that each eye should turn the vertical lines at one side of the field of sight slightly away from the perpendicular? As shown by a series of experiments in chapter i. of part ii. of Le Conte's " Sight," this is exactly what does happen; in the resultant image on the retina formed by the combined action of both eyes (see what is said of binocular vision in Chapter XVI.), the vertical lines, as they rise at the sides of the field of sight, seem, immediately above the horizontal level, to incline slightly away from the perpendicular in front of us. Nevertheless, at a comparatively short distance above this level, in accordance with the effect of the altogether different principle determined by distance or perspective which has already been pointed out, these same vertical lines seem to incline toward the perpendicular. It will be noticed, however, that, as applied to the horizontal lines above the level of the eyes, though less to those below it, this rotary action does not change, but, if anything, augments the effect of the upward curve described in the last paragraph. The fact just mentioned with reference to the side vertical lines, as well as the very slight effect which, when very near, is exerted upon...show more
