II, Part I (no further parts were published). This set is complete with the two parts of Vol.

The adoption of molecular formulas based on the laws of definite and multiple proportions, and the assignment of relative atomic masses, placed the science on a new quantitative footing” (Grossman, p. “In 1808 John Dalton published A New System of Chemical Philosophy, which described principles such as the uniqueness of atoms of the same element, relative atomic masses, and the rules of chemical combination, which taken together comprise the tablets of modern chemistry. 546-548 along with the 4 plates in part 2, in effect describe the first periodic table, which Mendeleev was to refine later. From his principles he deduced the law of definite proportions and the law of multiple proportions” (Dibner). “He developed a system of chemical symbols and a table showing the relative weights of the atoms of a list of elements. His equation of the concepts 'atom' and 'chemical element' was of fundamental importance, as it provided the chemist with a new and enormously fruitful model of reality” (Norman). 1), to formulate laws concerning their combination and to provide schematic representations of various possible combinations of atoms. Dalton's work with relative atomic weights prompted him to construct the first periodic table of the elements (in Vol. One of the chemical elements, and that these atoms remained unchanged during chemical processes. Dalton believed that all matter was composed of indestructible and indivisible atoms of various weights, each weight corresponding to “Dalton's chemical atomic theory was the first to give significance to the relative weights of the ultimate particles of all known compounds, and to provide a quantitative explanation of the phenomena of chemical reaction.

“Dalton reconstructed Newton's speculations on the structure of matter, and, applying them in a new form to chemistry, gave Lavoisier's reformation of that science a deeper significance” (PMM). Wilson, 1808 1810 1827.įirst edition, untouched in uniform original publisher’s bindings with original printed spine labels, of Dalton’s classic work on the atomic theory of matter.
