' The first great treatise on metallurgy written in modern times. It contains over 3,500 pp. of terse and exact description 

 of metallurgical processes, of minute and scientific discussion of the chemical problems they involve, often based on the 

 author's careful original research, and of suggestions for future investigations. The drawings of plants are remarkably 

 exact. The book, which has been translated into French and German, and has become a classic, involved an immense 

 amount of labour. Percy's work on alloys, his discovery of 'aluminium bronze,' and his view that in many countries the 

 iron age preceded the bronze age, deserve special mention '.D. N. B.
