    The postei-ior layer of the capsule compara- tively seldom gives trouble. If it does so, it can be easily needled. In my last 200 cases vision was tested on the 9th to the 14th days. In 33 cases or in 16 5 per cent, it was possible to re-test vision at a later date. This date varied from the 19th to the 60th day ; the average was 33 days. The final visual results as shown by E types, and by types for the illiterate, were as follows: in 3 per cent 6/6; in 3 per cent 6/8; in 16 per cent 6/12; in 21-5 per cent 6/18 ; in 24 5 per cent 6/24 ; in 14 5 per cent 6/36; in 6 5 per cent 6/60; in 8 per cent from 4/50 to 1/50; 1*5 per cent could do no more than count fingers; and in 1'5 per cent vision was lost. Of the re-examined cases 10 remained stationary, 2 receded in vision owing to acci- dents, and 21 showed a steady improvement. Had it been ])ossible to re-test a larger percent- age, it can hardly be doubted that the re- sults would have been greatly improved, but it is very hard to follow any large number of one's Indian cases. Arguing from my private cases, I should say that it takes usually six weeks to three months before the best vision is attained. As it was at this early date 89 per cent had ob- tained a vision from ^ to yV; ^ P^* cent from to-J^; 15 percent could count fingers and 1'5 per cent were failures. Five cases out of 200 obtained 6/6 vision by the 17th day and one on the 40th day. It is note- worthy tliat in not one of these cases was the whole capsule extracted, and in only one of them was even a fragment extracted. These figures are in direct contradiction to Major Smith's state- ment that by extraction in the capsule, vision is vecessariiy more acute than wlien capsule is left behind, for it is difficult to expect a better
