Édition originale de l'ouvrage majeur de Lecoq de Boisbaudran (1838-1912), chimiste français largement autodidacte qui « se classe aux côtés de Bunsen, Kirchhoff et Crookes parmi les fondateurs de la spectroscopie » (Weeks). Il a découvert le gallium, le samarium et le dysprosium et a mis au point des méthodes de séparation des terres rares, dont il a étudié les spectres pendant plusieurs décennies. L'auteur est surtout connu pour avoir utilisé le spectroscope dans l'analyse de composés inorganiques ; ce traité présente les résultats d'examens spectraux approfondis et précis portant sur trente-cinq éléments. Ces recherches avaient pour but de vérifier plusieurs généralisations reliant la longueur d'onde spectrale au poids atomique. Cet ouvrage parut un an avant la découverte du gallium par Lecoq de Boisbaudran (grâce à l'analyse spectroscopique) ? le premier des éléments prédits par Mendeleïev ?, apportant ainsi une confirmation expérimentale de la validité du tableau périodique.

The major work of Lecoq de Boisbaudran (1838-1912), a largely self-taught French chemist who "ranks with Bunsen, Kirchoff, and Crookes as one of the founders of the science of spectroscopy" (Weeks). He discovered gallium, samarium, and dysprosium and perfected methods of separating the rare earths, the spectra of which elements he studied for several decades. The author is best known for employing the spectroscope in the analysis of inorganic compounds, and the present treatise reports the results of extensive and refined spectral examinations of thirty-five elements. The research was undertaken to test several generalizations relating spectral wavelength to atomic weight. This work appeared a year before Lecoq de Boisbaudran discovered gallium (by spectroscopic analysis), the first of Mendeleev's predicted elements, thus providing experimental confirmation of the validity of the periodic table.

Hardcover. Condición: Very Good. No Jacket. 1st Edition. PIONEERING BOOK ON SPECTROSCOPY BY DISCOVERER OF GALLIUM. Paul Ãmile Lecoq de Boisbaudran, a French chemist, was born Apr. 18, 1838. De Boisbaudran was a pioneer in spectroscopic chemistry, by which new elements can be identified in compounds when unfamiliar lines show up in the compound's spectra. De Boisbaudran published the first French book on chemical spectroscopy, Spectres lumineux, in 1874. Putting his methods to good use, De Boisbaudran discovered four new elements in all, including samarium and europium. But his most famous discovery was gallium, which he detected spectroscopically in 1875 and isolated later that year. In 1869, Dmitrii Mendeleev had published his first periodic table. There were three notable "holes" in the table, places were elements would fit, and should fit, but which did not exist, at least according to contemporary chemical knowledge. Mendeleev, very sure of the soundness of his periodic arrangement, predicted that they do exist, and he even gave them names, based on the properties they should have by their place in his table. He called them "eka-boron," "eka-silicon," and "eka-aluminum", and in a way, he challenged chemists to find them. De Boisbaudran was the first to do so. His new element of 1875, which had an atomic weight of about 69, was very close to Mendeleev's predicted atomic weight for "eka-aluminum", 68. De Boisbaudran claimed that he named it gallium after the Latin word for France, but some suspected that he really named it after himself, since "Le Coq" means rooster, and rooster in Latin is "Gallus". Chemical names need more double meanings like this. Mendeleev later claimed to have discovered gallium himself, since his predicted properties, especially the density, turned out to be better than those that de Boisbaudran measured, which did not sit well with de Boisbaudran, or with lab chemists in general. Today, de Boisbaudran gets the credit, although you will never see a discussion of de Boisbaudran that does not include Mendeleev.

Premier travail important de Boisbaudran sur les méthodes spectroscopiques d'analyse élémentaire en chimie qui donnent les résultats de ses recherches exhaustives sur 35 éléments chimiques. Son ouvrage Spectres Lumineux parut un an avant sa découverte par analyse spectroscopique du gallium, le premier des éléments prédits par Mendeléev, fournissant ainsi une confirmation expérimentale de la validité de son tableau périodique. "Boisbaudran is best known for his work on spectroscopic methods of elementary analysis. In a volume entitled Spectres lumineux (1874), he reported the results of extensive and refined spectral examination of thirty-five elements. This work was undertaken to test several generalizations relating spectral wavelengh to atomic weight. In this work, Boisbaudran held that the various kinds of spectra for the elements were related to the various motions (rotation, vibration and translation) of the molecules. Boisbaudran was a winner of the 1879 Davy medal (for his discovery of gallium) and the Prix Lacaze.". (DSB II p. 254). Une oeuvre importante de spectroscopie chimique.

The papers: pp. 1003-1004 a. 1005-1006. First apperance of the papers in which Lecoc de Boisbaudran described how he separated Holmium into two kinds of earths and naming them."He accomplished this by fractional prepicitation, first with ammonium hydroxide and then with a saturated solution of potassium sulfate, and found that the constituents of pure holmium solutions precipitate in the folloeing order: terbium, dysprosium, holmium, and erbium. Lecog de Boisbaudran never had an abundant supply of raw materials for his remarkable researches on the rare earths, and he once confided to professor Urbain that most of his fractionations had been carried on on the marble slab of his fireplace."(Weeks "Discovery of the Eelements").Parkinson "Breakthroughs", 1886 C.…

Boisbaudran's paper: pp. 322-324. First apperance of the paper in which Boisbaudran revealed his discovery of a new earth that precipitated had a unique spectrum. De Boisbaudran named it samaria, after the mineral from which it was derived. The mineral samarskite is named for a Russian mining engineer and Chief of Staff - Corps of Mining Engineers, Colonel Vasili Evgrafovich Samarsky-Bykhovets."Samarium was discovered by French chemist Paul Émile Lecoq de Boisbaudran in 1879. He noticed in his research that impure didymium (praseodymium and neodymium with other impurities), seemed to contain more than just didymium based on spectroscopic work on various rare-earth minerals. When Lecoq de Boisbaudran added ammonium hydroxide to a concentrate prepared from the mineral samarskite he observed a precipitate that formed before the didymium (Weeks and Leicester, 1968, p. 685).

(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).…

First appearance of a milestone paper in chemistry and physics in which the author describes how he found the new element Gallium by analyzing spectral lines which he observed on a Pyrenea blende sample, the emission lines corresponding to the eka-aluminum that was predicted by Mendeleev in 1871 and he subsequently isolated the element by electrolysis. This was the first element discovered by use of the spark spectrum. In his discovery of the new element Boisbaudran was not guided by the predictions of Mendeleev, but only by his own law of spectra."Boisbaudran ranks with Bunsen, Kirchhoff, and Crookes as one of the founders of the science of spectroscopy."(Weeks)."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.

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). The plate shows the two spectral lines of gallium, which are distinct from those of other elements (indium and potassium) in the same region of the spectrum.
