| Title | Swan, Sir Joseph Wilson: certificate of election to the Royal Society |
| Citation | Has devoted himself for many years with great success to experimental scientific work, chiefly in relation to Electric Lighting, the Electro-deposition of Metals, and the Improvement of Photographic Processes. His labours have resulted in material extension of knowledge, and in important inventions among which are the Incandescent Electric Lamp, the Carbon Process, by which the first permanent photographic prints were produced and which has formed the basis of many processes of photo-mechanical engraving (in this relation the property of salts of sesquioxide of chromium to combine with gelatine and render it insoluble was discovered), the highly sensitive Gelatino-bromide Photographic Plate, the result of an original observation of the effect of heat on the gelatino-bromide of silver emulsion, the Cellular Form of Electrical Secondary Battery Plate, the production of Lamp Filaments from Solutions, Integrating Electric Meters, Safety Lamp for Miners, and an Electric Firedamp Indicator. |
