‎First edition of the first volume reporting the results from ""magnetische verein"", which was set up by Gauss and Weber under the inspiration from Humboldt.""Gauss and Weber organized the Magnetische Verein, which united a worldwide network of observatories. Its Resultate aus den Beobachtungen des magnetischen Vereins appeared in six volumes (1836–1841) and included fifteen papers by Gauss, twenty-three by Weber, and the joint Atlas des Erdmagnetismus (1840). These and other publications elsewhere dealt with problems of instrumentation (including one of several inventions of the bifilar magnetometer), reported observations of the horizontal and vertical components of magnetic force, and attempted to explain the observations in mathematical terms.""
