"Two days afterward the eye, which had been kept closed by means of court-plaster, was again opened. He now described what he saw as a number of opaque watery spheres, which moved with the movements of the eye, but when the eye was at rest remained stationary, and then partly covered each other. Two days after this the eye was again opened. The same phenomena were again observed, but the spheres were less opaque and somewhat transparent; their movements more steady; they appeared to cover each other more than before. He was now for the first time able, as he said, to look through the spheres, and to perceive a difference, but merely a difference, in the surrounding objects. When he directed his eye steadily toward an object, the visual impression produced by the object was painful and very imperfect, because the eye, on account of its intolerance of light, could not be kept open long enough for the formation of the idea as derived from visual sensation. The appearance of spheres diminished daily; they became smaller, clearer, and more pellucid, allowed objects to be seen more distinctly, and disappeared entirely after two weeks. The _muscae volitantes_, which had the form of black, immovable, and horizontal stripes, appeared, every time the eye was opened, in a direction upward and inward. When the eye was closed he observed, especially in the evening, in an outward and upward direction, an appearance of dark blue, violet, and red colors; these colors became gradually less intense, were shaded into bright orange, yellow, and green, which latter colors alone eventually remained, and in the course of five weeks disappeared entirely. As soon as the intolerance of light had so far abated that the patient could observe an object without pain, and for a sufficient time to gain an idea of it, the following experiments were made on different days. "_First Experiment._--Silk ribbons of different colors, fastened on a black ground, were employed to show the complementary colors. The patient recognized the different colors, with the exception of yellow and green, which he frequently confounded, but could distinguish when both were exhibited at the same time. He could point out each color correctly when a variety was shown him at the same time. Gray pleased him best; the effect of red, orange, and yellow was painful; that of violet and brown not painful, but disagreeable. Black produced subjective colors, and white occasioned the recurrence of _muscae volitantes_ in a most vehement degree.
