The History and Progress of the Electric Telegraph
With Descriptions of Some of the Apparatus
Description:... Excerpt from The History and Progress of the Electric Telegraph: With Descriptions of Some of the Apparatus
The favourable reception with which this work has been met by the public and the kindly expressions of encouragement and approval accorded to it by the press, not in England alone, have determined the publishers to reprint it, with some additions, in this smaller and cheaper form The edition in one volume is divided into two parts: the first containing a history of the rise and progress of the art of telegraphy, with descriptions of most of the apparatus in use at the present day; the second being devoted exclusively to the more scientific part of the subject, dealing particularly with matter having an immediate relation to submarine work. It has now been decided to separate these parts into distinct volumes, it being thought that there are many who, whilst interested in the history and apparatus, may not care for the scientific part; whilst others, and especially those connected with telegraphic engineering, may find only the information collected in the second part useful to them.
