 appendix on the Bessemer Process in the United States, by the 

 translator. Illustrated by lithographed drawings and wood-cuts.

 same time practical examination into the physical properties of steel, as well 

 as a description of the new processes and mechanical appliances for its manufac 

 ture. The information which it contains, gathered from many trustworthy 

 sources, will be found of much value to the American steel manufacturer, 

 who may thus acquaint himself with the results of careful and elaborate ex 

 periments in other countries, and better prepare himself for successful com 

 petition in this important industry with foreign makers. The fact that this 

 volume is from the pen of one of the ablest metallurgists of the present day, 

 cannot fail, we think, to secure for it a favorable consider ation. Iron Age.
