described and figured by Mr. Bennett {United Service 

 Journal) Jan. 1832) as an atoll. All the above-mentioned 

 islands have been coloured blue. 



Western Part of the Caroline Archipelago. — 

 Fats Island is ninety feet high, and is surrounded, as I 

 have been informed by Admiral Lutke, by a narrow reef 

 of living coral, of which the broadest part, as represented 

 in the charts, is only 150 yards; coloured red. — Philip 

 Isld., I believe, is low; but Hunter, in his Historical 

 Journal^ gives no clear account of it; uncoloured. — Elivi ; 

 from the manner in which the islets on the reefs are 

 engraved, in the atlas of the Astrolabe's voyage, I should 

 have thought they were above the ordinary height, but 

 Admiral Lutke assures me this is not the case : they form 

 a regular atoll; coloured blue. — Gouap (Eap of Chamisso) 

 is a high island with a reef (see chart in Voy. of Astrolabe), 

 more than a mile distant in most parts from the shore, 

 and two miles in one part. Capt. D'Urville thinks that 

 there would be anchorage {Hydrog. Descript. Astrolabe 

 Voyage, p. 436) for ships within the reef, if a passage could 

 be found; coloured pale blue. — Goulou, from the chart 

 in the Astrolabe's atlas, appears to be an atoll. D'Urville 

 (Hydrog. Descript., p. 437) speaks of the low islets on 

 the reef; coloured dark blue. 



Pelew Islds. — Krusenstern speaks of some of the 

 islands being mountainous ; the reefs are distant from the 

 shore, and there are spaces within them, and not opposite 

 valleys, with from ten to fifteen fathoms. According to 

 a MS. chart of the group by Lieut. Elmer in the Admiralty, 

 there is a large space within the reef with deepish water ; 

 although the high land does not hold a central position 

 with respect to the reefs, as is generally the case, I have 

 little doubt that the reefs of the Pelew Islands ought to
