    edematous ; prolapse at point of entrance of needle. Retina extensively detached and scarcely recognizable, being asso- ciated with a band of connective tissue and round and oval cells, and inflammatory material extending from nerve entrance to anterior portion of eye. Experiment 8.-2, 17, 1893. Full grown, white-nosed Mal- tese rabbit. Ten minims of aqua chlorinata injected into left vitreous. 3,6,1893. Vitreous has remained clear; that is, there have been no dark opacities or white infiltrations, and the eyeground is visible without apparent change in the retina. 3, 20, 93. Eye placed in Miiller's fluid, but not yet examined. Experiment 9.-2,17,1893. Full grown, gray rabbit. Ten minims of aqua chlorinata injected into left vitreous. 5, 6, 93. Extensive white clouding of the vitreous, and prob- able detachment of the retina. 3, 20, 1893. Eye placed in Miiller's fluid, but not yet examined. Experiment 10—3, 8, 1893. Full grown, white and gray rabbit. Ten minims of aqua chlorinata injected into right vitreous. 3, 11,1893. Cornea hazy and no view of fundus. (Probable contamination from imperfect sterilization of needle.) Experiment 11.—3, 8, 1893. Full grown white and gray rabbit. Five minims of aqua chlorinata injected into right vitreous. 3, 11, 1893. Large, greenish-white opacity well forward in the vitreous, giving . the appearance of an old detachment of the retina, and connective tissue formation in vitreous. No change before rabbit's death, three days later. Experiment 12.—3, 8, 1893 Full grown v^^hite and gray rab- bit. Ten minims of aqua chlorinata injected into right vitreous. 3,11,1893. Large greenish-white opacity obscuring the entire vitreous. Eye removed and placed in Miiller's fluid. Microscope.—Retina and choroid for the most part in place and of fairly normal appearance, but well forward on right side a circumscribed detachment of retina,the space between retina and choroid being filled with a granular material (coagulated vitreous) containing a number of hypertrophied vitreous cells. Experiment IS.—4, 17, 1893. Full grown black rabbit. Ten minims of aqua chlorinata injected into right vitreous. Immediately afterwards a large air bubble surrounded by a dark cloud. 4, 20, 1893. Circular white opacities and still some air bubbles present in the vitreous. 4, 28,1893. Several large, white opacities hanging in the vitreous surrounded, however, by clear vitreous, permitting a view of the fundus. No hemorrhages in the retina and no detachment. 5, 9, 1893. Practically no change from note under 4, 28, 1893. 5, 17, 1893. Irregular, dense, white opacities scattered
