TERRESTRIAL MAGNETISM An International Quarterly Journal Edited by L. A. BAUER With the Co-operation of Eminent Magneticians WITH the March, is , issue, this Journal, devoted exclusively to Terrestrial Magnetism and allied subjects, such as Earth Currents, Auroras, Atmospheric Electricity, etc., entered on its third 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, and de Tillo. Future numbers will contain : "The Height of the Aurora," BY PROF. CLEVELAND ABBE. "The Investigation of Hidden Periodicities in Terrestrial Magnetism and Meteorology," BY PROF. ARTHUR SCHUSTER, F.R.S. "The Relation of Terrestrial Magnetism to Geology," (As exhibited by recent investigations of various Authors.) " Descriptions of Magnetic Observatories," (Illustrated) BY THE DIRECTORS OF THE OBSERVATORIES. The size of the Journal is royal octavo, a volume embracing about 200 pages. Domestic subscription price: Two dollars; single numbers, fifty cents. Foreign subscription price: Nine shillings, nine marks, or eleven francs.
