NEW BOOKS AND PUBLICATIONS.

Metals and Their Chief Industrial Applications. By Charles R. Alder Wright. London: Macmillan & Co. 12mo; pp. 191. Price $1.25.

In this neat little volume we have the substance of a course of lectures delivered at the Royal Institution of Great Britain in 1877, with thirty or more engraved illustrations of various metallurgical operations. The author discusses briefly, yet with sufficient fullness for popular purposes, the principal processes for reducing metals from their ores, the natural sources of metals, the metallurgy of the different metals, the physical properties of metals, and their thermic, electric, and chemical relations. The style is simple and the matter well chosen.

Dosia. A Russian Story. Translated from the French of Henry Greville, by Mary Neal Sherwood. Boston: Estes & Lauriat. Price $1.50.

This is the seventh of the Cobweb Series of choice fiction, a bright, wholesome but rather thin story, as befits its associations. Novel readers will find it an amusing companion for a rainy day in the country, or for beguiling the tedium of a summer journey.
