Joseph HOËné-WRONSKI. Autograph manuscript signed, to Monsieur F. Arago, member of the provisional government and Minister of the Navy, April 8 [1848], plus copy with autograph addition; 15 pages in-fol. each. Petition for the reprinting of his Résolution générale des équations algébriques de tous les degrés, preceded by the Manifeste historique concernant l'actuelle réforme du savoir humain (Firmin Didot, 1847) and the publication of his Réforme de la philosophie. Wronski recalls his own military and scientific services to France, and his gratitude to the country of which he had become a citizen. But, still a victim of the Académie des Sciences, he demanded to be able to produce the definitive works concerning the reform of human knowledge on which the good of humanity depends, and in particular, his mathematical works. He offered the Minister of the Navy "the rigorous theory of the tides and its immediate practical application in all parts of our globe", according to his Prolegomena of Messianism (1843), then asked for national rewards for his work on railroads and his rectification of the metric system, in order to continue printing in France the second volume of the Reform of Human Knowledge, "namely, the Reform of Philosophy, in which [...] all the great problems of humanity are finally resolved. [...] I still bequeath to France half of this great work, which is already in print; and I pray to God that a man will soon be found to complete it, in order to accomplish the public good"... 2 autograph manuscripts are enclosed, Notice (3 pages and a quarter), and Nullité propre des insultes faites par les journaux, lors même qu'elles sont produites au nom de l'Académie des sciences de Paris (1p.).
