CHEMICAL PHENOMENA OF IEON SMELTING. An ex- 

 perimental and practical examination of the circumstances which 

 determine the capacity of the Blast Furnace, the Temperature 

 of the Air, and the Proper Condition of the Materials to be 

 operated upon. By I. LOWTHIAN BELL. 



" The reactions which take place in every foot of the blast-furnace have 

 been investigated, and the nature of every step in the process, from the intro- 

 duction of the ra\v material into the furnace to the production of the pig iron, 

 has been carefully ascertained, and recorded so fully that any one in the trade 

 can readily avail themselves of the knowledge acquired ; and we have no hes- 

 itation in saying that the judicious application of such knowledge will do 

 much to facilitate the introduction of arrangements which will still further 

 economize fuel, and at the same time permit of the quality of the resulting 

 metal being maintained, if not improved. The volume is one which no prac- 

 tical pig iron manufacturer can afford to be without if he be desirous of en- 

 tering upon that competition which nowadays is essential to progress, and 

 in issuing such a work Mr. Bell has entitled himself to the best thanks of 

 every member of the trade." London Mining Journal.
