Plate No. 4. 



This diagram shows the manner of inserting our blade 

 forceps No. 3. All other forceps must be inserted open with 

 one blade at each side of the head of the young, a thing often 

 very difficult if not impossible when the head is wedged in the 

 pelvis. There is, however, always room at the top of the 

 head, where our long, neat and perfectly shaped blades may 

 be easily inserted. The blades are then revolved to the sides 

 of the head, when owing to the joint, each blade adjusts 

 itself flatly on the head, allowing the severest pull without 

 injury to the young.
