about Mary Island ; both uncoloured. — Gardner Island (5° b., 

 174° W.), from its position, is certainly the same as Kemin 

 Island, and is described (Krusenstern, p. 435. Appen. to Mem. 

 published 1827) as having a lagoon in its centre ; coloured blue. 



Islands south of the Sandwich Archipelago. 



Christmas Island (2° N., 157° W.) : Captain Cook, in his 

 Third Voyage (vol. ii. chap, x.), has given a detailed account 

 of this atoll. The breadth of the islets on the reef is un- 

 usually great, and the sea near it does not deepen so suddenly 

 as is generally the case. It has more lately been visited by 

 Mr. F. D. Bennett (Geograph. Journ. vol. vii. p. 226) ; and 

 he assures me that it is low and of coral formation : I par- 

 ticularly mention this, because it is engraved with a capital 

 letter, signifying a high island, in D'Urville and Lottin's chart. 

 Mr. Couthouy, also, has given some account of it (Eemarks, 

 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 Fanning's 

 Voyage (p. 224), which, however, is far from clear ; coloured 

 blue. — Washington Island (4° N., 159° W.) is engraved 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 Johnston'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
