Fol-lowing this, at the time of extraction, the corneal section shouldbe made a trifle larger than the usual two-fifths of the limbus, andthe capsulotomy should include one-third of the lens the expression of the nucleus and opaque part of the cortex,the free use of a warm normal, salt solution injected into the. The Simple Anterior Chamber Irrigator Eeady for Use in the Extraction of Immature Cataract, anterior chamber and capsule with a suitable syringe, so as to washout as much as possible of the unexpelled lens matter will be foundvery satisfactory. There has long been in use at the New York Eyeand Ear Infirmary a round, soft, rubber bulb with a diameter of50 mm., having a capacity of two and a quarter ounces. To thisis attached a glass tube 55 mm. long, and having the diameter ofan ordinary eye dropper. Towards the end it tapers at an angleof 140°, is contracted at the mouth and flattened, having an open-ing 1 mm. broad. (See figure). An iridectomy preliminary to any form of cataract extractionenables the operator to remove leisurely and more accurately adefinite amount of the iris. Besides this advantage at the time ofextraction, there is less liability of the i
