‎First English edition of the first published papers from the famous ""Des Magnetischen Vereins im Jahre 1836"" for the study of the magnetism of the earth.""Gauss, one of the keenest and most original mathematical thinkers of all time, was joined by Weber for an intensive study of the nature and intensity of the earth's magnetism.. To enlist the observational help of others, they formed a society of international scope and published their observations annually for a dozen years. As part of their work, a telegraph line was erected in 1834 between the iron-free magnetic observatory and astronomical observatory at Göttingen.""(Dibner, Heralds of Science No. 66).""Gauss and Weber organized the Magnetische Verein (The Magnetic Association, mentioned in the title), 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.""(DSB).The offered part contains another importent paper by M.H. JACOBI ""Electro-Magnetic Experiments"", pp. 1-19 and 1 plate which is the first English translation of his importent paper ""Expéeriences électromagnétiques,"" in Bulletin de l’Académie impériale des sciences de St. Pétersbourg, 2 (1837), describingone of the first practical electrical motors.‎
