shoulder, and are tied behind the neck. The apex is 

 pinned behind the elbow. 



Stretcher. A stretcher on which to carry an injured 

 person may be made of two stout poles, 7 to 8 ft. long, 

 slipped through hems in the sides of a piece of canvas 

 6 ft. long by 16 in. wide. As a substitute for the canvas 

 in an emergency, two coats buttoned together over 

 poles may be used. A wide board, door, shutter, or 

 similar object may also be substituted. If nothing of 

 this sort is available, it is possible for a number of per- 

 sons so to carry an injured man as to avoid increased 

 injury and pain. In this case, no part should be allowed 

 to sag and there should therefore be as many supporting 

 points as possible. The lifting should be done by all 

 simultaneously, so that jar is avoided. 



Disinfecting solutions. For the disinfection of 

 wounds, several antiseptics are available, such as cor- 

 rosive sublimate, of the strength of 1 part to 1,000 parts 

 of water ; lysol in a 3 per cent solution, made by adding 

 f of a cup of water to a teaspoonful of lysol; carbolic 

 acid in a 3 per cent solution made similarly to lysol; 

 sulpho-naphthol (creolin) in a 3 per cent solution, 

 similarly prepared; and peroxide of hydrogen used full 

 strength as sold by druggists. In the absence of other 

 antiseptics, alcohol diluted with half as much water may 

 be used. Washing soap is antiseptic to a certain extent 

 and may be used in strong solution for thoroughly scrub- 

 bing around the wound. 



Of these disinfectants, the best for use in wet com- 

 presses are corrosive sublimate, 1 to 2,000; lysol in a 

 3 per cent solution ; and creolin, also in a 3 per cent 

 solution. Carbolic acid should never be used, as it 

 exert corrosive action upon the skin.
