Instructions nautiques sur le Canal de Mozambique, et sur les îles et les dangers dans les nord et nord-est de Madagascar, tirées et traduites de l'ouvrage anglais de James Horsburgh ; par M. Nonay, lieutenant de vaisseau

First edition (cf. Polak, 7057; Grandidier I, 2503).

Nineteenth-century Bradel-style binding of marbled paper-covered boards, brown sheep title-label, headcaps worn away, corners bumped.

Some little foxing.

This pamphlet contains a translation of a small portion of the monumental India Directory—more precisely, Directions for sailing to and from the East Indies, China, New Holland, Cape of Good Hope, and the interjacent ports, compiled chiefly from original journals and observations made during 21 years' experience in navigating those seas (1817)—by the Scottish hydrographer James Horsburgh (1762–1836), who was employed by the British East India Company.

The work remained the standard navigational authority for the East Indies until the 1850s.
