GENERAL NOTES. 
GEOGRAPHY AND TRAVELS.' 
GENERAL.—Dr. T. Fischer, in Petermann’s Mittheilungen, main- 
tains that when oceanic agencies alone have formed the coasts, 
it consists of a succession of arcs, in the case of steep coasts with 
a short, and of flat coasts with a long radius. Where the coasts 
exhibit other features, other causes, as movements of the earth’s 
crust, are either more powerful or are very recent. 
Arctic Recions——The Danish expedition to the east coast of 
Greenland returned to Copenhagen, Oct. 2d, after an absence of 
nearly three years. Besides the collection of valuable scientific 
material, Lieut. Hahn has made some important geographical and 
ethnographical discoveries. He wintered between latitudes 65° 
and 66° and reached 66.08° N., the highest point yet visited by 
uropeans on the coast. He has named the stretch of coast 
explored Christian IX’s land. 
The area of Store Baergefjeld, in Arctic Norway, has been rep- 
resented as an immense glacier field. The observations of Chas. 
\abot show that there are nearly seven secondary glaciers, hardly 
Passing beyond the stage of névé, and that their total area does 
not exceed six kilometers. The region is not a plateau, but to 
the north a mountain mass with summits nearly 6000 feet high, 
and averaging 3600 feet; and to the south a densely w 
table-land cut up by cajion-like valleys. Rabot has also found that 
distinct chains of mountains, reaching a height of more than 
3000 feet, exist in the Kola peninsula, between the White sea and 
fe IC The district is usually shown as a plain, broken
