‎First printing of the paper in which Boisbaudran announced his discovery of Gallium, together with the first printing of the paper in which he, by a series of experiments proved that Gallium, the metal that he had discovered amd named in honour of France, is a true element. A larger paper on the discovery was published in 1877 in ""Annales de Chimie et Physique"". In 1879 Bausbaudran was awarded the Davy Medal for his discovery of Gallium. ""In 1875 Boisbaudran spectroscopically discovered a new element, gallium, which he found in zinc blende from a mine in Hautes-Pyrénées. Continuing his work in Wurtz’s laboratory in Paris, he was a able to obtain the free metal by electrolysis of a solution of the hydroxide in potassium hydroxide. Gallium, Boisbaudran realized, was the ""eka-aluminum"" predicted by Mendeleev, and was the first of Mendeleev’s predicted elements to be isolated. Boisbaudran’s finding thus provided valuable evidence for the validity of Mendeleev’s periodic classification of the elements.""(DSB).""Lecoq de Boisbaudran announced his discovery (by spectroscopic analysis) of the new element gallium. Mendeleev had first predicted its existence and had named it eka-aluminium. The discovery was made in the author's private laboratory, in a specimen of zinc blende from the Pierrefitte mine in the Angelès Valley in the Hautes Pyrénées. He describes how on the evening of 27 August 1875 he detected the existence of this new element, which he named ""gallium"" in honor of France (Gallia)... A month later he ""performed in Wurtz's laboratory in Paris....a series of experiments to prove that gallium...is a true element""(Weeks). he discusses how he eventually isloated small amounts of pure metallic gallium and determined its physical and chemical properties. The paper (the paper offered) first describes gallium compounds (e.g., ammonium gallium alum,, chloride, oxide, and sulphate).""(Roy G. Neville II, p. 29).‎

‎N.M. Chernyshov Gold and Platinum Metal Mine of Black Shale Type in the Kursk-Vo‎

‎N.M. Chernyshov Gold and Platinum Metal Mine of Black Shale Type in the Kursk-Voronezh Region (Central Russia). In Russian (ask us if in doubt)/Chernyshov N.M. Zoloto-platinometallnoe orudenenie chernoslantsevogo tipa Kursko-Voronezhskogo regiona (Tsentralnaya Rossiya).. Voronezh Publishing House of Voronezh University 2007. The significant resources of a new unconventional large-volume source of benign metals concentrated in its subsoil serve as a reliable base for the expansion, reproduction and provision of mineral and raw material security in Russia. Formative genetic systematics are presented, regularities of placement are considered, a complex of borderline structural-material and ore-geochemical features of mining in multi-age black-shale layers and their metasomatites is singled out, the composition, peculiarities of distribution and forms of concentration of platinum and gold, and the genetic nature of ore-forming sources are described in detail.

‎Sur le Vanadium, métal nouveau, trouvé dans du fer en barres de Eckersholm. forge qui tire sa mine de Taberg, dans le Smaland.‎

‎(Paris, Crochard, 1831). No wrappers. In: ""Annales de Chimie et de Physique, Par MM. Gay-Lussac et Arago."", tome 46, Cahier 1. Pp. 5-112. (Entire issue offered). Sefström's paper: pp. 105-111.‎

‎First printing of the paper in which Sefström announced his discovery of a new element in iron from the Taberg mine in Småland. He named it Vanadium from the goddess Vanadis.Parkinson ""Breakthroughs"" 1831 C.The discovery and isolation of Vanadium has a long story to tell. In reality it was found by del Rio in 1801, he named it Erythronium, but upon further study he decided that he was mistaken as his further studies showed that it was made up of a basic lead chromate.‎
