Terrestrial Magnetism 



AND 



Atmospheric Electricity 



An International Quarterly Journal 



Conducted by L. A. BAUER, 

 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 Karth 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.

 mander Davis, Eschenhagen, Hellmann, I.ittlehales, McAdie, Riicker. Schmidt, Schuster, de Tillo, von 

 Bezold, Mascart, and Abbe.

 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 halftone portraits of eminent magneticians.
