Abstract
THE first edition of this book was well received by metallurgists, and a second has been called for. In addition to general revision, which has much improved the work, the subject of gases in metals has now been discussed in detail, mainly, however, in connexion with the non-ferrous metals. A fuller account of the state of knowledge concerning gases in steels, admittedly a controversial subject, would have been useful. The subject being the effect of impurities on the properties of metals, the section on magnetic properties might well have been expanded, in view of the enormous influence of even very minute quantities of impurity, of great theoretical significance as well as practical importance. Should another edition be required, the section on corrosion will also need expansion. The author's special acquaintance with tungsten enables him to illustrate several points by reference to that metal.
