Published in 18825, this two-volume work, illustrated throughout, appeared when electric lighting was a fresh and propitious technological development.With its spectacular lighting displays, the 1881 International Exposition of Electricity in Paris showcased the potential of the technology for commercial and domestic use. In its wake, James Dredge (18401906), editor of the British periodical Engineering, oversaw the compilation and publication in 18825 of this illustrated two-volume work.With its spectacular lighting displays, the 1881 International Exposition of Electricity in Paris showcased the potential of the technology for commercial and domestic use.

The accompanying International Congress of Electricians also agreed on international standards for units of electrical resistance, potential and current. In its wake, James Dredge (18401906), editor of the British periodical Engineering, compiled this illustrated overview of electrical technology and its application to lighting. First published in two volumes between 1882 and 1885, and using material that had previously appeared in Engineering, as well as new articles by various contributors, this substantial work reflects the complexities and possibilities of a propitious technological development. Among other topics, Volume 1 covers electrical units, methods of generation, conductors, and various kinds of lamp. The appendices give abstracts of British electrical patents from 1837 to 1872.Preface; Part I: 1. Electrical units; 2. The measurement of electrical intensity; 3. The voltaic arc; 4. The mechlóÉ
