ZIEGLERS FORCEPS. 235 which is first introduced, and thus serves as a guide to the Dr. Zieglers Forceps. These are the principal varieties introduced in the constructionof the instrument. We have endeavoured to explain the objectsintended by them. Among so many, each differing from theother, and all used by accoucheurs of acknowledged skill, it is noeasy matter to determine which forceps is the best. In makinga selection, therefore, of any, we must not be understood as wash-ing to depreciate the value of those we reject. In the construc-tion of these instruments, two different principles seem to havebeen followed. Some have wished to render the mechanism ofthe forceps as perfect as possible; others have sought simplicityin its construction. The former have contrived instruments ofgreat power, but which are not very easily applied ; the latterhave succeeded in the facility with which their forceps may beapplied, although with some of them the power is extremelylimited. Your late respected professor. Dr. Davis, contrived aforceps which you may take as an example of th
