Note 16 — Chapter V · THEORY OF THE FORMATION OF THE DIFFERENT CLASSES OF CORAL-REEFS.

The same remark is, perhaps, applicable to the islands of Ollap, Fanadik, and Tamatam in the Caroline Archipelago, of which charts are given in the atlas of Duperrey’s voyage: a line drawn through the linear reefs and lagoons of these three islands forms a semicircle. Consult also, the atlas of Lutké’s voyage; and for the Marshall group that of Kotzebue; for the Gilbert group consult the atlas of Duperrey’s voyage. Most of the points here referred to may, however, be seen in Krusenstern’s general Atlas of the Pacific.
