Supposing they are employed, three or four stout and semicircular curved needleSj each with a silver-wire or black silk thread, are inserted in a row above the cornea, at about half an inch from the corneal margin.

Then a puncture is made with a pointed knife through the coats of the eye at about half an inch external to the margin ot the cornea, and by it one blade of a blunt-pointed scissors is introduced, and so an oval piece of sclerotic, including the cornea, &c., is removed altogether, and just within the points at which, above and below, the needles traverse the sclerotic. Then the needles are drawn through, and the sutures are tied in knots each to each. THE OPHTHALMOSCOPE.
