A New System of Chemical Philosophy

Dalton's work is a monument of nineteenth-century science that transformed atomic theory and laid the basis for modern chemistry.

Dalton's Chemical Philosophy, which demonstrated the importance of the relative weight and structure of atomic particles, revolutionised atomic theory and laid the basis for modern chemistry. Volume 2 contains sections examining the weights and structures of two-element compounds for five different compound groups along with various notes and tables.The renowned English chemist and meteorologist John Dalton (1766–1844) published A New System of Chemical Philosophy in two volumes, between 1808 and 1827. Dalton's discovery of the importance of the relative weight and structure of particles of a compound for explaining chemical reactions transformed atomic theory and laid the basis for much of what is modern chemistry. Volume 2 was published in 1827. It contains sections examining the weights and structures of two-element compounds in five different groups: metallic oxides; earthly, alkaline and metallic sulphurets; earthly, alkaline and metallic phosphurets; carburet; and metallic alloys. An appendix contains a selection of brief notes and tables, including a new table of the relative weights of atoms. A planned second part was never published. Dalton's work is a monument of nineteenth-century chemistry. It will continue to be read and enjoyed by anybody interested in the history and development of science.
