    of the navy. To avoid this difficulty, I usually cut out a large piece from the centre of the membrane, and then cauterize the edges of the wound with nitrate of silver. Treat it as you will, however, this is often a most vexatious complaint, returning over and over again, and of course requiring repeated operations.—T. D. M.] TUMOURS. You meet with tumours in the corner of the eye growing from the conjunctiva, and sometimes involving the caruncula lachryma- lis. Sometimes warty tumours grow from the conjunctiva covering the ball of the eye; these are seldom of a bad character, and they may be taken hold of and dissected off freely enough. In removing tumours of this kind you must take away the tissue from which they grow, or they will return. Those tumours which grow in the inner corner of the eye require to be dissected off carefully so as not to injure the puncta lachrymalia or the little canals going from them. These must be avoided if possible. DEFORMED FISSURE. A person is sometimes brought to a surgeon on account of con- genital deformity, with the fissure of the lids badly placed. The fissure, perhaps, is out towards the temples, and in consequence of this he sees very indifferently; he cannot see right in front of him. This is not an uncommon occurrence. One of the pupils here, five or six years ago, laboured under this deformity, and it was remedied in the manner I shall describe. The fissure may be too small, and you may enlarge it; but in some cases something more is required. There may be too much skin in the middle line, and the fissures therefore are placed much too far on each side. This is very easily put to rights by pinching up a portion of the skin in the middle line over the glabella, and taking away the portion included by two elliptical incisions, the edges are then put together by a point of suture. The fissure of the lips is thus brought to its proper place, and you not only remedy the deformity but enable the patient to see better than he did before. [ptosis. The terms ptosis ; blepharo-ptosis ; lapsus palpebral superioris ; atonia palpebrarum, and ophthalmoplegia, have been applied to an affection of the upper lid, characterized by a loss of power in the muscles of the part, or preternatural elongation of the integument,
