188 GOODYEAR ON GUM-ELASTIC. 



TITFTED SPONGE. 



This is formed by vulcanizing a sheet of the sponge mass be- 

 tween two air-tight fabrics, which forms a coat upon each of the 

 fabrics, resembhng a heavy shag, fur, or plush, which is used as 

 a veneer or coating upon the bathing gloves and mittens, de-

SPONGE FABRIC. 



Gum-elastic sponge may be formed into a sheet of any desira- 

 ble thickness, unconnected with any other fabric, or it may be 

 laid upon or between other fabrics, either in the process of 

 manufacture or afterwards. 



The uses of the gum-elastic sponge fabric will undoubtedly 

 be very numerous ; but the article is so very novel that it is 

 yet too soon to attempt a very particular account of them. 



FIBROUS FABRICS: 



HEREAFTER DESCRIBED A3 TISSUE, VELLUM, PLATED FABRICS, FELT, AND 

 CORDED FABRICS. 



After the change was wrought in caoutchouc by the process 

 of vulcanization, comparatively few mechanical obstacles re- 

 mained in the way of its successful application to any articles 

 required to be made of the gum alone, or when uncombined 

 with any fabric or tissue ; but in all combinations where a
