The Chemical Analysis of Iron: .1 Complete 

 Account of \ll the Best-knoym Methods for the 

 Analysis of Iron, Steel, Pig-iron, Alloy \lelals.

 Blair's "Chemical Analysis of Iron" has Inn- 

 sin,,- made a name for itself among technical 

 manuals. About a quarter of a century has 

 elapsed since the writer of this notice first used 

 the book, the second edition of which had just 

 been published; and it is not surprising to find 

 that so useful a work is still in demand. 



Much has happened in the world of iron 

 analysis since those days. Chiefly the 1 hanges 

 have been in the increased use of steel alloys con- 

 taining more or less of the "rare " elements, such 

 anadium, uranium, molybdenum, and tung- 

 sten; and also of the "alloy metals," such as 

 tungsten and ferro-molybdenum. Methods 

 . ii> sing the former group have been brought 

 together in this edition of the book, and a 

 s1_p.1t.1i, section has been allotted to the alloy 

 metals. ["o chemists who have used former 

 editions it will uffice to say that the present one 

 has been rei and partly rewritten to include 



improvements ol processes, but preserves its 

 I, Miner characteristics "I concise accuracj and 

 judicious selection ol methods. To those un- 

 acquainted with the book- it may be said that they 

 will find in it all thi in rn ion necessai \ foi 

 carrying out iron and steel an; I; ;is to an) degree 

 ompleteness thai may be desired. The working 

 Ms are sufficiently full, nol 



elaborated, and users will find th
