TERRESTRIAL MAGNETISM AND ATMOSPHERIC ELECTRICITY An International Quarterly Journal Conducted by L. A. BAUER and THOMAS FRENCH, Jr., With the Co-operation of Eminent Magneticians and Electricians. WITH the March, 1899, issue, this Journal, devoted exclusively to Terrestrial Magnetism, Atmos pheric Electricity, and allied subjects, such as Earth Currents, Auroras, etc., entered on its fourth volume. The hearty co-operation extended by the workers in this promising field of investigation, as abundantly shown by the numbers thus far issued, has made this Journal the international organ for making known the latest achievements. The magnetic needle has become such a promising instrument of research, not only in terrestrial, but in cosmical physics, that this Journal appeals to a large class of investigators. The geographer, the geologist, the astronomer, the meteorologist-all are interested in the development of the subject of terrestrial magnetism. It should therefore receive their support. Among the contributors of the main articles in the past have been Messrs. Barus, Borgen, Chree, Com mander Davis, Eschenhagen, Hellmann, Littlehales, McAdie, Rucker, Schmidt, Schuster, de Tillo, von Bezold, Mascart, and Abbe. Future numbers will contain contributions by Mascart, Rucker, Elster and Geitel, Eschenhagen, Hellmann, Hayford, Littlehales, Schmidt, and others. Special features in future numbers will be full abstracts and reviews of recent publications prepared by competent reviewers and the series of fine half-tone portraits of eminent magneticians. The size of the Journal is royal octavo, a volume embracing about 256 pages. Domestic subscription price : Two dollars and fifty cents. Foreign subscription price : Two dollars and seventy-five cents. Address: TERRESTRIAL MIAG N ETISM, The University of Cincinnati, Cincinnati, Ohio.
