The simultaneous occurrence of
the perturbations, and the parallelism of the movements for October and
December, 1829, were then graphically represented. (Pogg., 'Annalen', bd.
xix., s. 357, taf. i.-iii.) An expedition into Northern Asia, undertaken in
1829, by command of the Emperor of Russia, soon gave me an opportunity of
working out my plan on a larger scale. The plan was laid before a select
committee of one of the Imperial Academies of Science, and, under the
protection of the Director of the Mining Department, Count von Cancrin, and
the excellent superintendence of Professor Kupffer, magnetic stations were
appointed over the whole of Northern Asia, from Nicolajeff, in the line
through Catharinenburg, Barnaul, and Nertschinsk, to Pekin.
[footnote continues] The year 1832 ('Gottinger gelehrte Anzeigen', st. 206)
is distinguished as the great epoch in which the profound author of a
general theory of terrestrial magnetism, Friedrich Gauss, erected apparatus,
constructed on a new principle, in the Gottingen Observatory. The magnetic
observatory was finished in 1834, and in the same year Gauss distributed new
instruments, with instructions for their use, in which the celebrated
physicist, Wilhelm Weber, took extreme interest, over a large portion of
Germany and Sweden, and the whole of Italy.
