Gymnastic ropes. Jump ropes. Inflated bat-club. Chest expanders. Baby jumpers. Swings. 



Invalids' jumper.

 vantage claimed for these over common ropes, unless it is their 

 elasticity and giving variety to articles constructed of them. 

 See plate xv., fig. 1. 



JUMP ROPES 



Are manufactured from elastic cordage. It is no better for 

 this purpose than common rope, except that" it may serve to 

 please better as a toy, and afford additional gymnastic exercise 

 and amusement, on account of its elasticity. 



INFLATED BAT-CLUB. 



This article is made of vellum or felt, and is inflated by a 

 self-acting valve tube at the end. They form a weapon, the 

 hardest blows from which are quite harmless. See plate xv., 

 fig. 2.
