    upward operation is performed, the blade must be bent at a more or less acute angle (Fig. 3; in this figure a narrower blade, curved at a medium angle, is shown), according to the prominence of the upper edge of the orbit. The blade must be bent at a still more acute angle if the iridectomy is to be made at the nasal side. If the anterior chamber is almost wanting, so that the ms is nearly in contact with the cornea, it may be pre- ferable to use a common extraction knife instead of the lance-shaped one. 4. The iris forceps should catch most accurately, and, when closed, should be perfectly smooth at the extremity, for if they are rough they will tear and scratch the iris and the lips of the incision, and thus perhaps set up some irritation. They may be straight (Fig. 4) when the operation is made outwards, although I, even here, prefer to have them sHghtly bent (Fig. 5). For the up- ward, or the nasal operation, they must be bent at a more acute angle. 5. A pair of iris scissors. Maunoir's (Fig. 6 ; I generally use a pair of this shape, but somewhat smaller) are the most useful. They are bent at an angle; though sharp, they are not too finely pointed. Care should be taken that the blades close tightly and do not override each other, which may easily occur in such slight scissors if the joint be not sufficiently strong and firm. Instead of these, a pair of scissors ctu-ved on the flat (as shown in Fig. 8) may also be employed. The patient is to be placed m the recumbent position, either in bed or on a couch, the head being shglitly ele- vated. Chloroform should be administered. I prefer to use it in aU cases of glaucoma, as the operation is often very painful, particularly if the eye is acutely inflamed; and however com'ageous and determined the patient may be, he may find it impossible to control some sudden, in-
