the part that is to be removed, so that it cannot be drawn 

 inside and thus increase the impediment to breathing. 

 After this, cut out a circular piece of the tube about an 

 inch in diameter — a part of two of the rings that com- 

 pose the windpipe, not the whole of one — using a narrow 

 bladed knife. Then insert a pewter, ivory, or box-wood 

 tube, with shoulders, and holes through the shoulders, so 

 that it may be fastened around the neck with strings. A 

 piece of elder, three inches long, with notches cut in it, 

 will answer the purpose.

 and, should the case take a 

 favorable turn, the tube may 

 be removed.

 of the partial escape of the air 

 through the artificial opening, 

 place the hand over it, and 

 thus compel the escape of the 

 breath through the larynx, the 

 proper channel. Fig. 5. The tube in use.
