PLATE Box, (Fie. 10.) 



These boxes are of wood, or ja- 

 panned metal, fitted with grooves 

 which prevent the plates from touch- 

 ing each other : they are very 

 necessary to prevent the plates from 

 being scratched or rubbed. 



FIXING STAND, (Fig. n.) 



This is a wire stand, made to support 

 the plate in an horizontal position, while 

 heat is applied in the fixing process : it is 

 also constructed with writing screws for 

 adjustment upon unequal surfaces.

THE WASHING TROUGH, (Fio. 12,) 



Is of metal, or Berlin ware, accompanied by a stand of earthen- 

 ware, by which the frame 

 is supported in the proper 

 position while washing. An 

 apparatus has been con- 

 structed for performing this 

 operation with greater ease 

 and certainty; it is, how- 

 ever, little used.
