The Heat Treatment of Tool Steel

THE fact that a demand has arisen for a second edition of this book within four years from its first appearance is the strongest evidence of its practical value. The author states in the preface that he is now less restrained than formerly, and is free to describe in greater detail the different methods of treating steel, and this has enabled him to deal with the subject much more completely than in the first edition. The Heat Treatment of Tool Steel. By H. Brearley. Second edition. Pp. xv + 223. (London: Longmans, Green and Co., 1916.) Price 10s. 6d. net.
