Only 4·94 per cent. of the total number of cases lie below the age of 36, and nearly 69 per cent. lie between the ages of 40 and 60. This is in accordance with what we know of senile cataract in India. Of the fourteen cases which show an age of 30 or below, eight may be excluded as having probably given their ages too low; one was lost by suppuration after couching, and no deduction can be made as to the condition before operation; in two it seems probable that the cataract was secondary to syphilitic iritis: they were two eyes of different persons; in one patient the operation failed on both sides: the eyes were congenitally imperfect, and in addition iritis was present as a complication in one of them. In the sixth the operator evidently burst the capsule and let out its semi-fluid contents; but the nucleus remained _in situ_ and blocked the pupil. It is obvious that couching is an extremely unsuitable operation for this class of case; it requires for its easy performance a firm lenticular mass, but as will be seen when we come to discuss the morbid anatomy of the subject, it is quite possible to dislocate one of these fluid lenses intact. There is at least a presumption that in such cases the posterior operation has been performed, though, in view of the toughness of the capsules of not a few Morgagnian cataracts, one cannot say with certainty in all such cases that the anterior operation has not been done. No table is more interesting than that which gives the state of vision when the patients came under observation. In only 10·59 per cent. was the vision 1/3 and upward. In another 11·05 per cent. the vision was 1/4 to 1/10, in 9·64 per cent. it was 1/10 to 1/50, and in 7·05 per cent. it was a finger-count at 2 feet or less. The figures given refer in each case to the vision corrected with lenses. If every case that got a vision of 1/10 and upward be considered a success, the coucher can claim 21·64 per cent. Again, if anything from 1/10 vision to the ability to count fingers close to the face be counted as partial success, the figure for this class is 16·69 cent. This is very much more liberal treatment than would be accorded to the cataract statistics of any modern surgeon. A further light is thrown on the above figures by a study of the table showing the duration of vision after couching. Of the 45 successful cases, 23 of them, or more than 50 per cent., had been couched less than two years before; 9 more had been couched between two and three years, and 11 from three to ten years. In two this detail was unmarked. The great preponderance of short histories in the cases of successful operation is significant.
