GREENLAND VOYAGE. 
greater than the quantity floating above the sur¬ 
face of the sea. Hence its weight must have 
been equivalent to a mass of sea-water of 1500 
feet square, and 700 feet thick, being the quan¬ 
tity that it displaced. The solid content of the 
water displaced, equal 1,575,000,000 cubic feet, 
divided by 35, the number of cubic teet of water 
of the Greenland Sea, in a ton weight, affords a 
quotient of forty-five millions of tons for the weight 
of the iceberg. 
On the 31st of July, we continued our course 
to the north-eastward, under a light breeze of 
wind, southerly, skirting the western edge of the 
floes, and towards evening penetrating among 
them. The latitude, at noon, was 70° 25'; lon¬ 
gitude 19° 11' W. An angle of the highest peak 
of Itoscoe Mountains, taken in passing them at a 
considerable distance, gave the altitude 4370 feet, 
which is probably a little too high. Saw a “ razor- 
back,” and several narwals. 
Early in the morning of the 1 st of August, a 
thick fog set in, and continued with little altera¬ 
tion the whole of the day. The next afternoon, 
having made a long stretch to the north-west¬ 
ward, in latitude 71° 50', we got a glimpse of the 
land, at the distance of about twenty miles. 
Then tacking, we stood off, as directly as the na¬ 
ture of the ice and bewildering fog would permit.
