Paris, Victor Masson et Fils, Imprimerie Gauthier-Villars, 1863. Without wrappers. In ""Annales de Chimie et de Physique"", Troisieme Series - Tome 67, Cahier Avril. Titlepage to tome 68. Pp. 385- 512 pp. and 1 folded colour plate (Spectre solaire, Spectre Thallium, showing the green line). (The entire issue offered). The papers on Thallium: pp. 385-434. Smal, stamps on verso of titlepage. Lamy's paper: pp. 383-417.
William Crookes was the first to observe Thallium (1861) as he found a new green line in a selenium sample, but Lamy was the first to isolate it and to prove that it was a metal (1862). The paper offered is Lamy's full description of his discovery, a shorter announcement was published in ""Comptes rendus"", 23 June 1862.Claude-Auguste Lamy (1820-1878) examined some slime from a sulfuric acid plant at Loos which was using Belgian pyrite and observed the green spectral line. He extracted thallium sesquichloride and isolated the metal new by electrolysis. Only after his discovery, he found out that Crookes had earlier discovered and named the new element, and gave Crookes the honour. Crookes presumed that his Thallium was something of the order of Sulphur, Selenium or Tellurium but Lamy found it to be a metal. In April 1862 he reported to the French Académie des sciences.

"LECOQ de BOISBAUDRAN, PAUL ÈMILE. - ANNOUNCING THE DISCOVERY OF THE ELEMENT GALLIUM.
Reference : 47271
(1875)
(Paris, Gauthier-Villars), 1875. 4to. No wrappers. In: ""Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences"", Tome 81, No 12 and No 23. Pp. (485-) 508 a. (1065-) 1148. (2 entire issues offered). Boisbaudran's papers: pp. 493-495 a. pp. 1100-1105.
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).
