‎---- EDITION ORIGINALE ---- BEL EXEMPLAIRE ---- "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)---- Partington IV p. 898**637/L4‎
