WITH RUBBER FEET AND HANDS, 



The engravins; is from an in- 

 stantaneous photograph of a man 

 ascending a ladder. He has two 

 artificial legs substituting 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.
