But a glance with oblique illumination was sufficient toshow that conical cornea did not exist. Throwing the light upon the eye with the ophthalmoscope at a distanceof about twelve inches, two images of the fundus could be seen simulta-neously. (See the accompanying Fig. i.) The central disc-like portion. Fig. I. of the pupil showed blood-vessels which were suddenly lost at its peri-phery, and the peripherical portion which encompassed the central discin the shape of a broad ring or zone showed blood-vessels, whichappeared to terminate quite as abruptly at its inner bordei-. Thediameter of the central portion was about equal to the breadth of thesurrounding zone, when the pupil was fully dilated. The observer, on moving his head from side to side, could distinctlysee that the vessels in the peripheric portion moved in the same direc-tion, while those in the centre moved in an opposite direction. Thiscould only be accounted for by the fact that the central portion of theeye was myopic, while the peripherical portion was hyperopic. Theblood-vessels in the centre belonged to an aerial, inverted (real) image,whereas those of the jjeriphery were seen in the virtual, upright image,which, in opposition to the former, showed a positive parallax in relati
