We come next to a group of 5 cases, which have one feature in common--viz., that the cataract, though _dislocated backwards, lies distinctly in front of the anterior hyaloid membrane_, and therefore outside the vitreous cavity (Pl. III., Figs. 20 and 21). In 3 of them the solid parts of the lenses have been pushed back from their original position in such a way that they act like wedges, forcibly keeping the anterior hyaloid membrane in a plane posterior to that which it would normally occupy. Out of these 5 cataracts 4 were cortico-nuclear; the fifth was too much altered for it to be possible to state what its nature was. In certainly 4 out of the 5 moderately severe iridocyclitis had followed the couching, but the exudative process was a much less severe one than that which characterised the specimens of the previous group. The consequence was that there was no such matting of all the parts concerned as is there seen. In every case the detachment of the retina was complete or nearly so, but in not one was the lens enwrapped in its folds. This we may attribute to two causes: (1) a merely contributory one, that the vitreous cavity was not invaded; and (2) that the infection was less virulent, and the inflammation consequently less severe, than in the members of the previous group. There is a small group of 3 cases in which the remains of the lens lie _in situ_ in the periphery of the capsule, whilst the central portion has disappeared. These resemble the peripheral after-cataracts not infrequently seen following the extraction of a not fully mature lens. In conclusion we have to mention 2 specimens in which the condition found was so unusual that it would scarcely have been possible to have anticipated its occurrence. The first of these was one of the earliest globes sectioned. A Morgagnian lens, entire in its capsule, was found _thrust behind the retina_. It lay against the scleral coat close to the ciliary body; it had detached the retina over a large area in the neighbourhood of the ora serrata, and had led to a complete separation of it on that (the nasal) half of the eye. The edge of the detached retina had contracted adhesions to the front of the lens capsule, and was much puckered in that neighbourhood, doubtless as the result of cicatrisation. The second specimen (Pl. IV., Fig. 22) shows many features in common with the last. The lens is entire in its capsule, and is almost certainly Morgagnian; the tear in the retina through which it was thrust has now cicatrised up, leaving a puckered scar. The retina is totally detached, and on section the cataract lay as far forward as the separation of that membrane would permit. The pupil was blocked by exudate, and atrophic scars in the iris showed that there had been extensive laceration of that membrane. The globe was removed a year after operation.
