To be recommended to the general reader who wishes to gain some knowledge of meteorology quickly. Not a text-book. Contains a chapter on “Flight in the Atmosphere.” _Elementary Meteorology._ WILLIAM MORRIS DAVIS. Boston, Ginn & Co., 1898. 8vo, pp. 355. $2.50. The most complete of the modern text-books, and the best adapted for use in the systematic teaching of meteorology. The modern views are presented clearly and without the use of mathematics. Portions of it are somewhat too advanced for school study, but teachers will find it invaluable as a reference book in directing the laboratory work, and in answering the questions of school classes. _A Popular Treatise on the Winds._ WILLIAM FERREL. New York, John Wiley & Sons, 1890. 8vo, pp. 505. $3.40. This can hardly be regarded as a _popular_ treatise. It embodies, in condensed and chiefly non-mathematical form, the results of Ferrel’s researches during his long and profound study of the general circulation and phenomena of the atmosphere. Teachers who advance far into meteorology will find this book indispensable. It is not at all suited for general class-room use. _American Weather._ A. W. GREELY. New York, Dodd, Mead & Co., 1888. 8vo, pp. 286. Out of print, but secondhand copies are probably obtainable. Deals, as the title implies, especially with the weather phenomena of the United States. Contains brief accounts of individual hot and cold waves, hurricanes, blizzards and tornadoes, and gives specific data concerning maxima and minima of temperature, precipitation, etc., in the United States. _Meteorology: Practical and Applied._ JOHN WILLIAM MOORE. London, F. J. Rebman, 1894. 8vo, pp. 445. 8 shillings.
