528 ESSAYS AND OBSERVATIONS 



The inftrument being thus armed,! pla- 

 ced the patient on a chair, with his face op- 

 pofitc to the light ; then holding the inftru- 

 ment by the handle D. and turning the 

 ends of the thread round my fore finger, 

 but fo as not in the lead to fhift the noofe 

 out of the groove, I pufhed the inftrument 

 into the patient's throat, till it reached 

 the pharynx, which brought on the ac- 

 tion of vomiting, and thereby forced up 

 the polypus through the ring of the in- 

 ftrument, which was contrived fo large as 

 to fill up all the fpace in his throat. Im- 

 mediately, on feeing all the polypus in his 

 mouth, I thruft the inftrument to the 

 root of it with the left hand, and pulling 

 the threads with the other hand, made a 

 firm noofe on it. I then withdrew the 

 inftrument, and allowed the threads to 

 repafs the tubes B. upon which he 

 fwallowed the polypus with the thread, 

 the ends of which hung out of his 

 mouth. The time employed in cafting 

 this noofe was fo momentary, that the 

 patient was in no danger for want o£ 

 bieatb.
