Abstract
THIS convenient and carefully prepared manual supplies a want that has long been felt. Many of the elementary substances, long regarded as merely chemical curiosities, are now finding useful and often extensive applications in the arts. In the manufacture of filaments for electric lamps, in the preparation of mantles for gas-lighting, in various cases in which hardness or infusibility iare desiderata, and especially in the production of steels with special qualities, a large and ever-increasing number of the so-called “rare metals” are finding familiar uses.
