but as this method is often contra-indicated on account of 

 gangrene, approaching gangrenous states, and especially 

 owing to uncontrollable straining, amputation is often the 

 only possible recourse. 



The technique is as follows : The patient is secured and

 healthy zone in front of the prolapsed portion; a series of 

 interrupted sutures are placed around the whole circum- 

 ference as near the anus as possible, and an amputation ef-

 needle similarly armed is then passed in the same direction 

 one-half inch from the first one, the four threads are then cut 

 from the needles and one of them from the first needle is 

 tied to one from the second, first internally and then exter- 

 nally. This leaves a tied stitch between two loose untied 

 threads. A third needle, armed in the same manner, is then 

 passed in the same direction and the same distance from the 

 second and immediately cut off. Then the free thread from 

 the second stitch is tied to one of the threads of the third and 

 so on until the whole circumference is sutured. The free
