CRUTCHES. 169 



DISSECTING APRONS. 



This article may be best made of gum-elastic vellum, in the 

 form of a frock, with sleeves attached. When worn with the 

 gloves before described, the hands will not only be protected, but 

 the person will also be protected from the offensive effluvia of 

 the dissecting room. 



FINGER ENDS, OR COTS. 



Cots are made of gum-elastic drapery and perforated drapery. 

 They are used by fishermen and mechanics, and they are also 

 very useful for the cure of cut and wounded fingers. When pro- 

 tected by them, the hands may be washed in hot or cold water 

 with impunity. 



CRUTCHES. 



This article is made in two parts, in order that it may be 

 taken to pieces and packed for travelling. The head is covered 

 with a cushion of elastic sponge, and a spring or cushion of the 

 same material is inserted, either in the socket between the parts, 

 or at the end. These two cushions have the effect to make 

 them quite easy for walking. 



The wood may be covered with gum-elastic vellum, put on 

 with glue. This covering prevents the unpleasant rattling noise 

 commonly attending the use of crutches. 



An improved and beautiful article of this kind is also made of 

 caoutchouc whalebone, of various patterns. See plate , fig.
