WITH RUBBER FEET AND HANDS. 



The 



engravmc; is from an iti- 

 photograph of a man 

 ascending a ladder. He has two 

 artificial legs substUutins his nat- 

 ural ones, which were crushed by 

 a railroad accident and subs-^- 

 quently amputated, With his 

 rubber feet he is able to ascend 

 or descend a ladder, balance 

 himself on the rungs, and have 

 his hands at liberty. He can earn 

 a good day's wages at the bench. 

 He can walk and mingle with per- 

 sons without betraying his loss ; 

 in fact he is restored to his former 

 self forall practical purposes. 



With the old methods of com- 

 plicated ankle-joints an undertak- 

 ing of this kind w-nuld be at the 

 peril of the wear-^r, but with the 

 rubber feet he can venture into 

 all sorts of ope-ations with safety. 



Over eight thousand in practical 

 use, scattered in all parts of the 



tho 



ndo; 

 It to tho 



nd testi- 



needing 

 ficial legs or arms, who will give 

 description of their catie. T\ 

 same will be sent to physiciai 

 and surgeons free of charge.
