The work systematically analyzes simple and composite inorganic compounds, treating metallic oxides, sulphurets, phosphurets, carburets, and a wide range of alloys. It presents experimental procedures for preparing, weighing, and distinguishing oxides, examines combination ratios and bonding hypotheses, and tabulates properties and reactions across many metals and earths. Sections collect experimental observations on specific heats, thermal expansion, refrigeration, and vapor pressures, with numerical tables and commentary on contemporary measurements. Appendices synthesize data and practical tables for experimental use, and the author indicates further parts will address more complex products such as acids, salts, and organic-derived substances.
