The two branches are articulated in a manner peculiar to M. Charriere (dtenoti), which admits of their being readily dismounted. The patient being placed in a suitable position, the operator grasps the instru-ment by its handle, with his right hand, and introduces it to the head of thefoetus by passing it along the palmar surface of the fore and middle fingers of theleft hand, which also serve to keep it in its place; it is then rotated on its axis likea punch, until it penetrates the cranium, which is indicated by the cessation of55 866 DYSTOCIA. resistance. Then, and not before, the instrument is opened for the purpose ofenlarging the aperture. To effect this, the left hand retains its position, andholds the instrument, whilst the extremities of the four fingers of the right handpress upon the lever D, the handle resting upon the thenar eminence.

The brain is afterwards broken up by inserting the instrument still deeper,and moving it in all directions. Before withdrawing the craniotome, it is allowed to close itself, after whichits extraction from the genital parts is unattended with danger either to thevaginal mucous membrane, or to the fingers of the operator. The principal advantages of this instrument may be summed up as follows : 1. Great solidity and simplicity. 2. Introduction and withdrawal entirely safe, rendering it capable of beingused by the least experienced operators. 3. Capability of acting by pressure, and that with a single hand, the otherremaining at liberty to guide the instrument, keep it in its place, and know whatbecomes of i
