The December Number closes the 15th volume of this admirable monthly magazine. It is one of those able scientific serials of which Americans may well be proud. A marked feature is the employment of specialists for separate departments. Entomology is edited by Prof. Riley; Botany by Prof. Bessey; Microscopy by Dr. R. H. Ward; Geography by Ellis Yarnall; Anthropology by Otis Mason, and next year a new department, Mineralogy, will be under the charge of Prof. Carvill Lewis, one of the ablest of the rising generation of scientists.

It is published, at $4 a year, by McCalla & Stavely, Philadelphia.
