    EXPLANATION OF PLATE XII. EXPLANATION OF THE FORCFPS OF PROFESSOR SIEBOLD. We have been favoured, by the politeness of Dr. Eberle, with a sight of professor Siebold's forceps. In their general form and size, they differ but little from the forceps of Baudelocque ; they are rather longer in the clams, and a little more curved, as will be seen by examining the plates. What we value in them is, their very ingenious mode of lock- ing ; we are persuaded this has a decided advantage in some po- sitions of the head, and will contribute to the success of applica- tion.
