B. Text-Books.

The Story of the Earth’s Atmosphere. Douglas Archibald. New York, D. Appleton & Co., 1898. 18mo, pp. 194. 40 cents.

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.
