Palaia Kameni*) was formed, and since that, as it seems, many 
other rocks have been raised in its centre. In 1427, this island 
was increased. In 1573, the Little Kameni was thrown up, eX- 
actly in the centre of the basin, accompanied with an ejection of 
steam and pumice ; and between 1707 and 1709, was raised the 
New Kameni, which still continues to send forth sulphurous va- 
pors.+ Lastly, in the present moment another new island seems 
to be about to appear to the east of Kameni, about 900 feet from 
the coast of Santorin, according to the report of a naval officer of 
Santorin,t (Nauplia, 4th December, 1834.) 'The inhabitants of 
the island assert, that thirty years ago this bank lay at the depth 
of 90 feet; in 1820, it was only 60 feet below the surface; and 
at present the sea is only 20 feet deep over it. According to later 
accounts given in the public journals, this bank continues to rise 
so rapidly, that if it meet with no interruption in its progress, it 
will, by the year 1840, be able to lay claim to the denomination 
of an island. In the year 1713, it is said an island arose among 
the small islands near Venice, accompanied with flames, smoke, 
and the most vehement shocks. 'This phenomenon, which con- 
tinued. four weeks, drove away the inhabitants from the adjacent 
islands. After about two years a similar occurrence was repeate 
and a second island was thrown up under the same circumstances. 
These two islands are now, as the neighboring ones, inhabit 
and cultivated.$ 
From Leop. Von Buch’s instructive exposition of the nature of 
voleanic phenomena,|| which, together with the careful works of 
Von Hoff, contain a critical compilation of all cases yet known © 
the production of new mountaius and islands by volcanic action, 
we will borrow only the following examples of recent date. 
first I shall mention is the island of Sabrina, near St. Miguel, 
the Azores, which is celebrated’ for the many islands that have
