PACIFIC OCEAN.

Lutke (vol. ii. p. 304) seems to have thought that all the low 
islands, with only one exception, contained lagoons. The 
most southern island in the group, namely, Piguiram, is not 
coloured, because I have found no account of it. Noitgouor, 
or Monte Verclison, which was not visited by Lutke, is 
described and figured by Mr. Bennett (United Service 
Journal, Jan. 1832) as an atoll. All the before-mentioned 
islands have been coloured blue. It must, however, be 
stated that between Ualan and Pouynipete, the three 
McAskill Islands rise to a height of from 40 to 100 feet, 
and consist, according to Dana (Corals and Coral Islands, 
p. 306), of coral-rock; whether they are encircled or fringed 
by coral-reefs does not seem to be known. 
Western part of the Caroline Archipelago.— Fais 
Island is 90 feet high, and is surrounded, as I have been in- 
formed 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 Island, 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 
that this is not the case : they form a regular atoll ; co- 
loured blue. Gouap ( Eap of Chamisso) is a high island 
with a reef (see Chart in Voyage of Astrolabe) in most parts 
more than a mile distant from the shore, and two miles in 
one part. Captain 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 ; co- 
loured pale blue. — Goulou, from the chart in the Astrolabe's 
atlas, appears to be an atoll : D’Urville (Hydrog. Descript, 
p. 437) speaks of low islets on the reef ; coloured dark blue. 
Pelew Islands. — Krusenstern speaks of some of the 
islands being mountainous ; the reefs are distant from the
