Paper covered boards. Nice copy! The dustjacket has the remnants of a library call number on it--but for that there's really nothing wrong with this copy. Fresh.

Mémoire sur les Combinaisons du Phosphore, et particulièrement sur celles de ce corps avec l’hydrogène” in “Annales de Chimie et de Physique.”
Dumas, Jean Baptiste André. "Mémoire sur les Combinaisons du Phosphore, et particulièrement sur celles de ce corps avec l'hydrogène" in "Annales de Chimie et de Physique, Par MM. Gay-Lussac et Arago," Paris, Crochard, 1826 (February), volume 31, 113-223, folding plate, with the Dumas on pp113-153. Original wrappers. Nice copy. VG condition. 135.00 [++] "Dumas was one of the leading chemists in France in the mid-19th century. He is best known for the Dumas method of determining atomic and molecular weights and for determining the atomic weights of thirty chemical elements. Eventually his method was superseded by other techniques, including mass spectroscopy. Dumas is also known for the Dumas method of determining the amount of nitrogen in chemical substances. This method is still widely used, especially to determine the protein content of foods, because it is relatively fast and easy to use and fully automatable."--Society of Catholic Scientists. [++]"Jean Baptiste André Dumas (1800-1884) was a French chemist, best known for his works on organic analysis and synthesis, as well as the determination of atomic weights and molecular weights by measuring vapor densities. He also developed a method for the analysis of nitrogen in compounds."-_Wikipedia "In 1826 he devised a method of measuring vapour density. He went on to discover various organic compounds, including anthracene (1832), urethane (1833), and methanol (1834), which led him in 1840 to propose the theory of types (functional groups)."--ibid. Additionally "He was a masterful teacher, serving as mentor to many important French chemists, including Auguste Laurent, Charles-Adolphe Wurtz, and Louis Pasteur"--Britannica See: Jane Woodward, "Jean Baptiste André Dumas" Journal of Chemical Education 1951 28 (12), 630.

E.M. McCormick. E.M. McCormick. Digital Computer Primer. McGraw-Hill, 1959. Nice copy in a dustjacket EXCEPT there is some sort of dampstaining along the top of the textblock. Not a bad copy, really kinda of nice, in cloth, with a dustjacket. I'd just like to move this along hence the low price. Cheaper than a paperback reprint of this classic!- $15
