This furnace has been designed specially for cupellation work and assaying. 

 The sketch attached shows the accommodation for a Patent Battersea Muffle J. the inside dimensions cf 

 which are nf in. long by sj in. wide by 3! in. high, this being equal to the interior working space of a Rattersea 

 Muffle J. 



Great economy will be found in using this furnace, as it is only necessary to use sufficient fuel to reach the level 

 fof the floor of the muffle, the products of combustion then being sufficient to successfully cary out all metallurgical 

 Japerations. 



The improved method of supporting the muffle insures a longer life to the latter. 



The furnace is fitted with draught regulator, so that the flow of air over the charges being treated can be 

 \ ncreased or decreased at will. 



Free oxygen is introduced through the patent channels of the muffles simultaneously over the surface of all 

 liie charges under operation, thus obtaining rapid and equal result s, and reducing the loss by volatilisation to a 

 ^minimum. 



The height of the furnace is 24 in. ; width, 20 in. ; depth, 18 in. Total weight of furnace, 425 Ibs. Chimney, 

 to Ibs.
