Leipzig, Johann Ambrosius Barth, 1812. Without wrappers. In: "Annalen der Physik und der Physikalischen Chemie. Hrsg. Ludwig Wilhelm Gilbert", Bd. 12 (= Bd. 42 der Reihe), Neuntes Stück. Titlepage to vol. 12. Pp. 1-116 a. 1 engraved plate. (The entire issue offered). Berzelius' paper: pp. 37-89. First German edition of this classic paper in chemistry in which Berzelius presented his system of nomenclature to the scientific world. The paper was first preseted in French "Essay sur la nomenclature chimique" in Journal de Physique the year before (1811)."Of his contributions, moreover, to the development of the atomic theory and the advancement of chemical science, not the least valuable was the introduction of a chemical symbolism which, with slight modifivcations, is in use at the present day. By giving his symbols a quantitative meaning - the symbol of an element representing one atomic proportion by weight - it was possible "to show briefly and clearly the number of elementary atoms in each compound and, after the determination of their relative weights, present the results of each analysis in a si8mple and easely retained manner.". This symbolism was speedily adopted on the Continent but, en England, only after some considerable time."(Findley "A Hundred Year of Chemistry", p. 14). - Holmberg, Bibliografi öfver Berzelius, 1812:7). …

London, Robert Baldwin, 1813. 8vo. Contemp. hcalf. Marbled boards. Spine lacks and boards loose. In: "Annals of Philosophy" or Magazine of Chemistry, Mineralogy, Mechanics. By Thomas Thomson". Vol. II. - VIII,480 pp. a. 7 plates. (Entire volume offered). Berzelius' paper: pp. 276-284, 357-368. Some browning and brownspots to plates. First printing of this milestone papers in the history of chemistry, where Berzelius introduced his famous chemical symbolism (the offered paper is the first on the subject - Leicester & Klickstein calls it the "Preliminary note) whereby an element is generally represented by the first letter of its Latin name, or, in the event of elements having the same first letter, by the first two letters. Even though his atomic symbols were introduced in 1813 (see the note on p. 359), it was quite a few years before Berzelius's symbols were adopted by the chemistry community. But once accepted, they became the new international language of chemistry. Berzelius "contributed more to the development of the atomic theory and to the setting up of accurate values of the atomic weights than did any other worker of the time. Of his contributions, moreover, to the development of the atomic theory and the advancement of chemical science, not the least valuable was the introduction of a chemical symbolism which, with slight modification, is in use at the present day.

In: "Annales de Chimie, ou Recueil de Mémoires concernant la Chemie" Tome 78, 79, 80, 81, 82 and 83. (Entire volumes offered). The 14 parts: (Tome 78:) pp. 5-37, 105-132, 217-242. - (Tome 79:) pp. 113-142, 233-264. - (Tome 80:) pp. 5-37, 225-258. - (Tome 81:) pp. 5-36, 278-303. - (Tome 82:) pp. 5-33, 113-125, 225-72. (Tome 83:) pp. 5-35 a. pp. 117-127. With in all 3 engraved plates. Some scattered brownspots. The papers represents one of the first announcements of Berzelius' discovery of the fixed chemical proportions, determining the weights and valencies of the various constituent elements in inorganic compounds. The papers were published at the same time in Swedish, German (both here in Annalen and in Schweiger's Journal), and in French. By running many hundreds of analysis of chemical compounds he gave so many examples of the law of definite proportions that the world of chemistry could no longer doubt its validity, and in so doing he gave experimental evidence to the atomic theory. He hereby laid a solid fundation for the further development of chemistry. A reprint is found in Ostwald's Klassiker der exakten Wissenschaften, No. 35.According to Söderbaum (Jac. Berzelius, 2, p.12) "It was a giant work, one of the most importent in the history of chemistry, which was here presented. One is even more impressed when one remembers that it was a pioneer undertaking in every sense of the term. Analytic and synthetic methods existed before Berzelius' time, to be sure, but there were no precise methods of the sort which he required. They all had to be elaborated at the cost of time and labour."(J. Erik Jorpes "Jac. Berzelius", p.45)."In general Berzelius's efforts were directed toward the consolidation and extension of the atomic theory. He improved chemical analysis and determined the composition of a large number of compounds, thus verifying the laws of constant and multiple proportions and furnishing the most accurate equivalent weights then available. By ingenious methods he arrived at the correct atomic composition of most common substances, and thus was enabled to draw up (in 1826) a table of atomic weights very nearly identical with the modern one."(Leicester & Klicktein "A Source Book in Chemistry", p. 258).Parkinson "Breakthroughs", 1810-20 C. …
