small letters in the French chart, but in Krusenstem’s

Maeshall Geoup. — We are well acquainted with this 
group from the excellent charts of the separate islands, made 
during the two voyages of Kotzebue : a reduced one of the 
whole group may be seen in Krusenstern’s Atlas, and in 
Kotzebue’s Second Voyage. The group consists (with the 
exception of two little, islands which probably have had their 
lagoon filled up) of a double row of 23 large and well-cha- 
racterized atolls, from the examination of which Chamisso 
drew up his well-known account of coral formations. I in- 
clude in this group Gaspar Rico, or Cornwallis Island, which 
is described by Chamisso (Kotzebue’s First Voyage, vol. iii. 
p. 179) ‘ as a low sickle-formed group, with mould only on 
the windward side.’ Gaspard Island is considered by some 
geographers as a distinct island lying N.E. of the group, 
but it is not entered in the chart by Krusenstern ; left un- 
coloured. In the S. W. part of this group lies Baring Island, 
of which little is known (see Krusenstern’s Appendix, 1835, 
p. 149). I have left it uncoloured ; but Boston Island I 
have coloured blue, as it is described (ibid.) as consisting of 
14 small islands, which, no doubt, inclose a lagoOn, as re- 
presented in a chart in the Coquille's atlas. — Three islands, 
Aur, Kawen and Gaspar Rico, are written in the French 
chart with capital letters ; but this is an error, for from the 
account given by Chamisso in Kotzebue’s First Voyage, they 
are certainly low. The nature, position, and even existence 
of the shoals and small islands north of the Marshall group 
are doubtful. 
New Hebeides. — Any chart, on even a small scale, of 
these islands will show that their shores are almost without 
reefs, 1 presenting a remarkable contrast with those of New 
1 [The New Hebrides have fringing-reefs in various parts. No 
barrier-reefs are yet known, but the charts are still very imperfect.
