The journal continued the volume numbering of its predecessor. The journal was suspended from January 1943 to January 1949, and again from 1960 to 1977. 45-50 francs a year, 20-68 pp. (varies). It touted itself as being "scientific," with the "goal of verifying scientifically, outside of all philosophical systems, the influence of the stars on man, social, political, and economic events, and generally on all areas of nature." In effect, however, the journal carried the customary prognostications for the coming period, interspersed with more general discussions, especially on the purpose and future of astrology. It carried the astro-diagnosis of Max Heindel (advertisements for whose work appeared in the journal), discussions of the horoscope of the late Pius XI and Mrs. Simpson, favorable periods for surgery and for becoming pregnant, and, during the War, it presented the horoscope of General De Gaulle with an analysis of his chances (good). Touchingly, the issue for August 1939 predicts disturbances in the north of Scotland and in Greenland, but ignored the coming of World War II. The journal called special attention to its analysis of "fluctuations boursieres et influences cosmiques," on which the Institut Central Belge de Recherches Astro-Dynamiques that published this journal, also published from 1930 on Bulletins Financiers, quarterly, monthly and weekly, in limited editions (price on demand), to guide financiers and speculators, and ran a Studio Astrologique to teach students the rudiments of astrology. Brahy (1894-1989) was an occultist, theosophist and Martinist and a Rosicrucian of the Max Heindel persuasion, and the journal occasionally carried articles on those subjects. Jean Delville was for a time the honorary president of the Institute. Pierre Geyraud, L'occultisme a Paris (1953) noted the work of H.-J. Gouchon in the journal. Advertised in L'Astrosophie, 1930 and 1939, and Cahiers Astrologiques, 1938.
