fetus to which they may be applied, whether the tissues be soft 

 or hard. They have been used in obstetric practice for a great 

 many years, but have not acquired a very wide application. 



They consist in many cases of two powerful, sharp blades ope- 

 rated as shears by some mechanism which gives them sufficient 

 power to cut through an extremity at any point where it may 

 be grasped. Sometimes the instrument is constructed somewhat 

 on the plan of an ecraseur, and by some mechanical appliance 

 a sharp chain is forced through the tissues. Representing this 

 type of instrument, which has recently become quite popular 

 in Germany, is the Pflanz embryotome, Fig. 99, and the Pflanz 

 extractor. Fig. 100.

The former consists of a heavy frame-work which might be 

 likened to that of an ecraseur, with an ordinary strong chain, 

 which is passed around the part of the fetus to be divided. By 

 drawing upon this, the sharp chain or sector is brought in contact 

 with the part to be amputated and forced through the soft tis- 

 sues and bone.
