A Practical Treatise on Gas-light Exhibiting a Summary Description of the Apparatus and Machinery Best Calculated for Illuminating Streets, Houses, and Manufactories, with Carburetted Hydrogen, or Coal-Gas, with Remarks on the Utility, Safety, and General Nature of this new Branch of Civil Economy.

This compact yet thorough work opens a window onto the early days of street and domestic illumination by gas. Written by a seasoned chemist who witnessed the first large‑scale experiments, the author walks the reader through the basic chemistry of coal‑derived gases and the way they replace candles and oil lamps. The opening sections explain how light is measured, why coal‑gas glows brighter, and what proportions of fuel are needed for a steady flame.

Beyond theory, the treatise offers clear diagrams of the retorts, regulators and distribution pipes that make a city‑wide system possible. Practical tables let the reader calculate installation and running costs, compare them with traditional lighting, and assess safety precautions. Illustrated with seven coloured plates, the book also discusses which public and private settings benefit most from gas‑light and where the technology proves less suitable, giving a balanced view of its economic promise and limitations.
