madreporic

Updated: June 11, 2025

On the morning of the 24th, in latitude 12 degrees 5' south and longitude 94 degrees 33', we raised Keeling Island, a madreporic upheaving planted with magnificent coconut trees, which had been visited by Mr. Darwin and Captain Fitzroy. The Nautilus cruised along a short distance off the shore of this desert island.

At the part of Samow I visited the people all understood it, which is very remarkable, as only a narrow strait separates the islands. In this state of ignorance they may perhaps be purposely kept. I here recognised several Australian shrubs and palms. The rock of which this port of Rottee is formed appeared of a madreporic nature, scattered about in huge blocks.
