Over half the signal books in this category are French; the other nations represented are Spain, the Kingdom of the Two Sicilies, Sweden and Turkey. There are eighteen volumes, 1754 to 1885, the majority of which are printed with manuscript annotations. Of the French volumes, the earliest is a signal book kept in 1754 by the pilot of LA ROSE, in the squadron of Le Comte de Gallissoniere (1693-1756). The volume has a thumb index of coloured flags and is illustrated with watercolours of fleet manoeuvres. There is also an English translation of the signal book issued by the Comte D'Ache (1700-1775) to his fleet while in the East Indies in the ZODIAQUE, 1757 to 1759; a signal book issued by the Comte D'Orvilliers (1708-1792) in 1779; and a printed signal book of 1787 issued by the Marquis de Nieul, in which the names of the vessels in the squadron have been scratched out, but the twenty flags and ten pendants have been coloured. The Revolutionary War period is represented by three signal books issued for the navy of the Republic in 1799 and 1801. Only one has actually been issued and gives a key to the flags. In addition, there is a handbook for a coastal semaphore between Bayonne and Flushing; published in 1807, the system was invented by an artillery officer named Depillon and built ca.1803. The category also includes two signal books for the Kingdom of the Two Sicilies; one was issued in ca.1784 by John (later Sir John) Acton (1736-1811), the other in 1816; a Spanish book of signals and instructions printed in Cadiz in 1765 and issued by the Marques de la Victoria; another Spanish volume for 1781 for the fleet of Don Luis de Cordova; and two Swedish volumes, 1795 and 1796. The Turkish signal book is naval, 1885, and the format is similar to a French or an English volume. There is also a Dutch volume of flags rather than signals which was compiled ca.1687; it is described on the title page as 'The Flagbook of Captain Paulus van der Dussen' (1658-1707).
