南磁極
On 25 February, the schooners sailed towards the Auckland Islands, where they carried out magnetic measurements and they left a commemorative plate of their visit (as had the commander of "Porpoise" previously), in which they announced the discovery of the South Magnetic Pole. They returned via New Zealand, the Torres Strait, Timor, Réunion, Saint Helena and finally Toulon, returning on 6 November 1840, the last French expedition of exploration to sail.
