Art. XIX. — On the Volcano^ called hy the Japanese Goosima^’ 
and situated in the neighbourhood of Cape Sangar, in 
the Archipelago of Japan. By Dr Tilesius, Russian 
Counsellor of State, and Member of the Imperial Academy 
of Sciences of Petersburgh, of the Wernerian Natural His- 
tory Society, &c. &c. &c. Communicated by the Author. 
T'hE smallest volcanic rock, in a sea of islands, can only be 
regarded as the peak or summit of the mountain, projecting but 
a short way above the surface of the water. The first voyage 
of the Russians round the globe, in the years 1803 — 6, under 
the command of the honourable and learned Captain Krusen- 
stern, by whom I was appointed to the situation of natural his- 
torian, gave me an opportunity of mailing a near survey of a 
small volcano of this kind, and of sketching it on four sides. 
After our departure from Japan, in die month of May 1805, 
when we had passed Matmai and Cape Sangar, and were direct- 
ing our course towards the Kurile Islands, and Kamskatka, 
we fell in with the two small volcanic islands Oosima arnd Coo- 
sima. Krusenstern himself, in the second part of the account 
of his expedition, pages 30, 33, and 34, has described this voy- 
age with all its details, and takes this opportunity of represent- 
ing both these islands, and their nearest-lying promontories, 
Cape Sinecho^ Cape Sangar^ and Cape Nadeschda^^ the town 
Matsmai, Cape Greig., and the Peak Tilesius it is 
already known that all the rocks of this archipelago are more or 
less of a volcanic nature. In the chart of the Strait of Sangar, 
(from the same atlas) Krusenstern has represented these two 
volcanoes, which are still continually smoking, as lying between 
139° and 140° longitude, opposite to Cape Sangar, or between 
this and Cape Greig, along with which they form a triangle. 
There is a view from them of Cape Gamaley, and of Peak Ti- 
lesius. They are drawn on the great scale in Tab. 68., or in 
the chart of the west coast of Jesso in the atlas of Krusenstern. 
Prom this point there is a view of Okosir and Cape Sinecko, 
of Cape Gamaley, and the peak Tilesius. The islands* lie
