An excerpt from —New Technical Books, Vol. 1 [1915]:

Johnstone, Sydney J. The rare earth industry, including the manufacture of incandescent mantles, pyrophoric alloys, and electrical glow lamps. Together with a chapter on the industry of radioactive substances, by Alexander S. Russell ... London: Crosby Lockwood & Son, 1915. xii, 136 p. illus. 4°. (Manuals of chemical technology, no. 2.)

"The importance at the present time of the rare earths and radioactive substances can hardly be over-estimated. Out of their technical utilisation most important industries have recently arisen, the whole subject of gas and electrical lighting has been revolutionised, the match industry has been attacked, while certain branches of surgery and medicine have entirely changed their course within a few years. With the advent of the rarer elements into technology, moreover, has dated the discovery of a whole series of very remarkable steels, which have again reacted on the engineering industries, and on the progress of invention in a way which at present it is difficult to adequately estimate."— From the preface.

This is a practical, well illustrated treatise dealing less with the pure chemistry of rare earths than with their industrial applications. There are numerous bibliographical and patent references.
