The strength of the branches is sufficientto incise the long process of the incus without trouble.* In order to use theinstrument for both ears, the upper portion is changeable by means of ascrew. The operation is carried out as follows: the instrument with closedbranches is introduced in a horizontal direction nearly to the long process ofthe incus, when the scissors are opened, slightly advanced, and the longprocess of the incus, which may now be felt between the branches, is incisedb\ closing the scissors. In order to prevent the adhesion of the incised ends,.
