This superb work, initially published in 1816, was the first British publication on military bridges. The author, a distinguished soldier who made a name for himself serving in Canada and Spain, held the position of Commandant of the Senior Department at the Royal Military College. It was for the College's use that he originally composed this work as a text-book and it is believed to have supplied Thomas Telford with the idea of the principle of suspension in bridge construction. This is the improved second edition, published in 1832, which was significantly enlarged in comparison to the first edition. This edition also contains a frontispiece and twelve superbly improved plates, all of which are folding and contain a number of diagrams to each. SCARCE.
