Paris, Crochard, 1832. No wrappers. In: "Annales de Chimie et de Physique", 2e Series, vol. 51, Cahier 3. With titlepage to vol. 51.Pp. 225-336 a. 1 engraved plate. (Entire issue offered with titlepage to vol. 51). Wöhler a. Liebig's paper: pp. 273-308 a.1 engraved plate - Berzeliu's paper: pp. 308-314. Some scattered brownspots.

First apperance, but together with the publication in Liebig's Annalen the same year, of Wöhler and Liebig's milestone paper in which they brought order to the complexity of organic compounds. The paper was followed with berzelius' letter in which he praised the authors for their remarkable work and he indicates how their compounds could be represented by formulas. The paper initiated a search for common radicals in other organic compounds from chemists all over the world.

"The first significent step in finding the order behind the bewildering complexity of organic compounds was made by Wöhler and Liebig in their joint researc on benzaldehyde (oil of bitter almonds) and its derivatives. Here for the first time it was clealy seen that a group of atoms could remain intact throughout a series of reactions and function as a whole - as a radical..... Gay-Lussac's researches on cyanogen confirmed the possibility of the existence of organic radicals, but they first became really significant with the this study of Wöhler and Liebig."
