GENERAL NOTES. 
GEOGRAPHY AND TRAVELS.' 
Tue Durcu Circumpoiar Expepition.—On July 5, 1882, the 
Dutch expedition embarked on the Norwegian steamer Varna. 
Before the end of August the Varna was surrounded by ice at 
about 70° N. lat. and 63° E. long. On September 18th the Dan- 
ish steamer Dijmphna perceived the ship and attempted to render 
aid, but was itself surrounded by ice, and soon both ships were 
frozen in at about seventy-five yards distance from each other. 
At the commencement of October enormous crevasses opened in 
the ice, heralded by loud noises of cracking and splitting, and 
the crew, who at the first warning had left the ship, found them- 
selves completely separated from it. After the crevasses had 
frozen over, the crew regained the ship, and continued observa- 
tions until Christmas eve, when the ice floes again put themselves 
in Motion, crashing against each other with such force that the 
‘arna was literally crushed. The crew escaped with safety, and 
with their documents, instruments, dogs and sledges, took refuge 
on board the Dijmphna, the solid construction of which enabled 
it to resist the movement of the ice. 
tere they were compelled to remain until August rst, when, 
as the Dijmphna had orders to spend a second winter in the Arc- 
tic, they made for the land by means of boats and sledges, and 
reached Waigatz island in three weeks. Here they fell in with 
the Louise, the Nordenskjold and the Obi, all sent in search of caw 
Varna, All collections and papers were saved; and not one 
the crew was lost, in spite of the hardships endured.
