The journal was devoted to socialism, magnetism and spiritualism. Besides its discussion of the work of the various spiritualist groups in Belgium the content of the journal consisted largely of material reprinted from other journals, together with book and journal reviews, and biographies of prominent spiritualists. In its later years the journal carried conferences given by Georges Le Clement de Saint-Marcq, the work of Victor Henrion, and the conferences of the Jules Fievet’s alchemy group. The journal still existed in April 1913 when Mysteria lists it among its exchanges, and is said to have ceased in 1914.
