CLAUDET'S FRAME AND IMPROVED DITTO. 



Both these frames are used for carrying prepared plates. The 

 first is a thin metal frame, of the same dimensions as the plates it 

 is intended to carry, and is placed between them to keep them 

 from the light, and to prevent their touching each other, or gather- 

 ing dust. In this state they may be tied together, and carried in 

 the pocket without danger. The second is the same frame in a 

 metal case, which closes tightly, and still more effectually secures 

 them from light, dust, or contact.
