Traité de télégraphie sous-marine

First edition, illustrated with a folding map and 469 engravings within the text.

Contemporary half black shagreen, the spine with four raised bands ruled in gilt and decorated with triple blind-tooled panels, marbled paper boards, marbled endpapers and pastedowns; a few small scuffs to the edges, corners slightly rubbed.

Contents include: history; construction and manufacture of telegraph cables; laying and repair of submarine cables; electrical testing; fault detection; signal transmission; and the operation of submarine lines.

The author, Jules Hippolyte Eugène Wünschendorff (1840–1901), was an engineer with the telegraph service and director of military telegraphy.

A pleasing copy.
