In den WarenkorbParis, Victor Masson et Fils, 1866. 8vo. Contemp. hcalf, raised bands, gilt spine. Light wear along edges. Wear to top of spine. Small stamps on verso of titlepage. In "Annales de Chimie et de Physique", 4ieme Series - Tome IX. 528 pp., 2 folded plates. (The entire volume offered). Stas' paper: pp. 215-243. Internally clean and…fine. First French printing of Stas's importent (first) paper in which he demonstrates the incommensurability of the atomic weights, proving that atomic weights are not whole numbers or multiples of halv or a quarter of the atomic weight of hydrogen."Stas demonstrated that the values of the atomic weights he had determined were neither multiples of unity, nor of one half, as Marignac believed, nor of one quarter, as Dumas maintained. This publication led Marignac to doubt the universality of the law of definite proportions. In three papers collectively entitled "Nouvelles recherches sur les lois des proportions chimiques, sur les poids atomiques et leurs rapports mutuels" (1865), Stas presented the results of an extensive series of experiments devoted to the new demonstration. By painstaking and accurate measurements he established that atomic weights were incommensurable, thereby disproving the facile conclusion that discrepancies with whole-number values were due merely to experimental errors. Prout?s hypothesis was thus discredited."(DSB).

In den Warenkorb(Paris, Bachelier), 1840. 4to. No wrappers. In: "Comptes Rendus Hebdomadaires des Séances de L'Academie des Sciences", Tome XI , No 25. Pp. (991-) 1020. (Entire issue offered). The paper: pp. (991-) 1008. A bit of marginal soiling and some creasing to leaves. First appearance of the paper which states the correct weight of the c…arbon atom. This research had profound influence on the development of organic chemistry. The paper in full was published the year after (1841) in "Annales de Chimie et de Physique"."From 1840 onward he carried out an important revision of the atomic weights of thirty elements. His most valuable contribution in this field was his very precise determination of the atomic weight of carbon (jointly with his pupil Stas) in 1840. A previously accepted weight, determined by Berzelius as C = 12.20 (O = 16), was shown to be incorrect. Dumas proved that C = 12±.002 (O = 16) or C = 75 (O = 100). The analysis was made by burning diamond and artificial and natural graphite in oxygen" the carbon dioxide formed was weighed in potash solution. The results were in close agreement. The "new" weight of carbon had a great effect on the progress of organic chemistry."(DSB).

In den Warenkorb(Paris, Fortin, Masson et Cie, 1840). 8vo. Without wrappers. Extracted from 'Annales de Chimie et de Physique', 2e Series, tome 73. Pp. 73-103 (incl. Note de Liebig pp. 100-103) and pp. 113-166. Some scattered brownspots. This paper, which was published at the same year in "Comptes Rendues" (3 Fevrier), is the most importent on…the theory of structural types and the nomenclature of organic compounds, refuting the electrochemical theory of Berzelius. "The development of this idea (type organique) into what is sometimes called the "Older Type Theory", as distinguished from Gerhardt's Type heory, is contained in Dumas' importent memoir on the substitution and the theory of types, presented on 3 febriary 1840."(Partington IV, p. 365). In the second paper Stas and Dumas record the first use of 'potash-lime', the precursor of soda-lime, an invaluable reagent in organic chemistry."Jean Baptiste Dumas advances a theory that the chemical properties of an organic compound are determined by its structure and not, as seems to be the case with inorganic compounds, by its electrical properties. he illustrates the concept with the example that the basic qualitative properties of acetic acid are retained even after replacing three fourths of the hydrogen by chlorine. As a consequence, he calls for a revision of chemical nomenclature for organic compounds, basing terms on common features, not on elemental composition."(Parkinson "Breakthroughs" 1840 C).
