Belatedly overhauling my signal codes page(s), currently here, and now working on Sebastien François Bigot de Morogues (1706-1781) his Tactique navale, ou, Traité des Évolutions et des signaux (1763), and looking at (scans of) this Dutch and a later (1797) English translation. “Evolutions” are the choreographed movements of fleets as they change course and/or divide, typically in engagements with an enemy. The success of the evolution hinges on signals. Volume 1 shows the evolutions (in diagrams); Volume 2 (here) discusses (and provides signals for) the evolutions.

Inadequate and confused ideas follow with the same necessity as adequate, or clear and distinct ideas.
