In 1816, Sir Francis Ronalds (1788-1873) became the first physicist to demonstrate the possibility of an electric telegraph. Previously, the only telegraphs were semaphores - cumbersome signal towers capable of sending only two or three words per minute. However, his idea was dismissed by the Admiralty, where senior officials deemed any new telegraphs 'unnecessary'. Although his designs were soon to be superseded by those of the more successful Samuel Morse, Ronalds' devotion to telegraphy never waned; he spent much of his life collecting books on the subject. Upon his death, his collection was left to the Society of Telegraph Engineers, where it would become available to those most in need of it. Covering more than 13,000 titles, and including a short memoir of Ronalds, this book, first published in 1880, is a catalogue of that collection and other relevant works. It remains an invaluable resource for students in the history of science.

First published in 1880, this is a complete catalogue of the traders and products that featured in an exhibition at London's Agricultural Hall, 5-17 July 1880. The focus of the exhibition was printing, stationery, papermaking and related trades, and around 200 organisations participated, displaying items such as printing appliances, papermaking machinery, stationery materials, packaging, and precision instruments. The catalogue's editor, journalist Lucien Wolf (1857-1930), prefaces it with an informative overview of trade exhibitions, examining their history and future, and their role in bringing together producers, retailers, buyers, wholesalers and importers to assess competition, compare products and evaluate the state and progress of their trades. The main body of the catalogue contains information on exhibitors and their products, and a range of authentic advertisements. Providing a revealing snapshot of industrial England, this work remains of interest to historians and scholars interested in Victorian trade.
