Le dernier rapport d'un Européen sur Ghât et les Touareg de l'Aïr

A traveler's combined day-by-day journal and formal field report of expeditions in the central Sahara around Ghât, the Aïr and the Tasili, mixing route descriptions with systematic natural-history observation. The text records landscape and climate notes, geological and vegetation remarks, meteorological registers and mapped itineraries, and ethnographic observations of Tuareg communities and oasis life. Practical details about caravan movements, water sources and geographic obstacles alternate with precise notes on local flora and fauna. Translator annotations and a brief biographical notice supply contextual material and collect scattered measurements and place-names into indices and appendices.
