Paul T. Passalskij

[In order to make accessible Passalskij's memorable treatise1 to the readers of the Journal, who are unfamiliar with the Russian language, Prof. Paul Wernicke, working under the auspices of the Department of Terrestrial Magnetism of the Carnegie Institution of Washington, has translated the portions of chief interest, the first installment of which is given in the present number. For a biographical sketch of the author and a brief résumé of the contents of Passalskij's work, see Professor Leyst's article, this Journal, Vol. VII, pp. 67–74. The author during his all‐too brief life, he having died November 25, 1900, at the age of twenty‐nine years, evinced unusual talents, a tireless industry and an unbounded enthusiasm for magnetic work.—ED.]

Abstract We have seen (art. 380) that the action of magnets on one another can be accurately represented by the attractions and repulsions of an imaginary substance called ‘magnetic matter.’ we have shewn the reasons why we must not suppose this magnetic matter to move from one part of a magnet to another through a sensible distance, as at first sight it appears to do when we magnetize a bar, and we were led to poisson’s hypothesis that the magnetic matter is strictly confined to single molecules of the magnetic substance, so that a magnetized molecule is one in which the opposite kinds of magnetic matter are more or less separated towards opposite poles of the molecule, but so that no part of either can ever be actually separated from the molecule (art.430)
