When cutting the carcass, a bottle is found inside the fish, in which a request for assistance is written in three languages from a victim of a shipwreck.

The documents have been strongly spoiled by water, however they manage to decipher that Captain Grant's ship has crashed on the 37th degree south latitude.

The travelers move by land and sea, cross Patagonia by the 37th parallel, visit the islands of Tristan da Cunha, and Amsterdam, pass by the south-eastern Australia and New Zealand.
