À travers l'hémisphère sud, ou Mon second voyage autour du monde. Tome 2 / Équateur, Panama, Antilles, Mexique, Îles Sandwich, Nouvelle-Zélande, Tasmanie, Australie.

The author recounts a second round-the-world voyage through the southern hemisphere, offering descriptive travel accounts of Ecuador, Panama, the Caribbean, Mexico, the Sandwich Islands, New Zealand, Tasmania and Australia. He reports on geography, cities and ports, agricultural and extractive products (cacao, rubber, quinine), infrastructure projects like the Panama canal, colonial administration and social conditions, and contrasts Anglo-Saxon colonial development with Spanish-American stagnation. The narrative combines travelogue, historical sketches and social commentary, praising immigrant-driven enterprise, moral and legal customs in settler colonies, and urging educational and legal reforms at home while proposing travel as a practical means of instruction.
