Rare first edition of the pharmacy thesis of Polydore Boullay, a chemist who played an interesting role in the early pre-theory of atomic volumes. "In 1830, the French chemist Polydore Boullay (1806-1835) wrote his doctoral thesis on the subject of atomic volumes (16). In it, Boullay reported that he had been unsuccessful in finding what he had initially sought: a law relating the atomic volume of an element in the uncombined state to that of its volume after combination. But he went on to suggest another kind of relationship: that the atomic volumes of the elements were correlated with their cohesive ability. Boullay noted that the greatest cohesion is found for elements with the smallest atomic volume (such as carbon), and the weakest for elements with the largest volume (such as sodium and potassium)." (Mendeleev, Meyer, and atomic volumes. An introduction of an English translation of Mendeleev's 1869 article "on the Atomic volume of simple bodies" by Gregory S. Girolami and Vera V. Mainz in Bull. Hist. Chem., VOLUME 44, Number 2 (2019), page 101). Some foxing.
