length of the lava currents, by reference to the MS. of Mr.
Paulson, who visited the tract in 1794, and examined the lava
with attention. (Journal of a Residence in Iceland, &c. p.
229.) Some of the principal facts are also corroborated by Sir
William Hooker, in his "Tour in Iceland," vol. ii. p. 128.

[593] In a former edition, I selected the name of Sciacca out
of seven which had been proposed; but the Royal and
Geographical Societies have now adopted Graham Island; a name
given by Capt. Senhouse, R. N., the first who succeeded in
landing on it. The seven rival names are Nerita, Ferdinanda,
Hotham, Graham, Corrao, Sciacca, Julia. As the isle was
visible for only about three months, this is an instance of a
wanton multiplication of synonyms which has scarcely ever been
outdone even in the annals of zoology and botany.

[597] In the annexed sketch (fig. 60), drawn by M. Joinville,
who accompanied M. C. Prevost, the beds seem to slope towards
the centre of the crater; but I am informed by M. Prevost that
these lines were not intended by the artist to represent the
dip of the beds.
