PACIFIC OCEAN.

given some account of it (Remarks, p. 46) from the 
Hawaiian Spectator ; he believes it has lately undergone a 
small elevation, but his evidence does not appear to me 
satisfactory ; the deepest part of the lagoon is said to be 
only ten feet ; nevertheless, I have coloured it blue. — Fan- 
ning Island (4° N., 158° W.), according to Captain Tromelin 
(Ann. Maritim. 1829, p. 283), is an atoll : his account, as 
observed by Krusenstern, differs from that given in Fan- 
ning’s Voyage (p. 224), which, however, is far from clear ; 
coloured blue. — Washington Island (4° N., 159° W.) is en- 
graved as a low island in D’Urville’s chart, but is described 
by Fanning (p. 226) as having a much greater elevation than 
Fanning Island, and hence I presume it is not an atoll ; 
not coloured. — Palmyra Island (6° N., 162° W.) is an atoll 
divided into two parts (Krusenstern’ s Mem. Suppl. p. 50, 
also Fanning’s Voyage, p. 233) ; blue. — Smyth's, or John- 
ston’s Islands (17° N., 170° W.) : Captain Smyth, R.N., 
has had the kindness to inform me that they consist of two 
very low small islands, with a dangerous reef off the east 
end of them ; Captain Smyth does not recollect whether 
these islets, together with the reef, surrounded a lagoon ; 
uncoloured. 
Sandwich Archipelago. — Hawaii : in the chart in 
Freycinet’s Atlas small portions of the coast are fringed 
by reefs ; and in the accompanying Hydrog. Memoir, reefs 
are mentioned in several places, and the coral is said to 
injure the cables ; but Dana saw hardly any reefs here. 1 
1 [Prof. Dana, noticing tliis remark in Silliman’s Amer. Jour., Dec. 
1874, states the result of further enquiries on his part from the Eev. 
Mr. M'Coan, long a resident of Hilo : — ‘ With respect to your enquiry 
whether there is any elevated coral-reef rock around the shores of 
Hawaii, I would reply that I think not. . . . Honolulu, on the island of 
Oahu, is built much of it upon the elevated coral-reef rock, and there 
are large areas in the district of Waiana and other portions of the Oahu 
shores : but there is nothing of this kind on Hawaii. You are aware 
that corals, even under the water, are on the weather [eastern] side
