356 H. MOHN. METEOROLOGY. [2nd arc. exp. pram 



given in the ship's journal of the Fram, and from Capt. Sverdrup's 

 description of the voyage. The positions found by dead reckoning have 

 been corrected by means of the astronomical determinations of latitude 

 and longitude. 



In some cases it has been very difficult, or impossible, to find the 

 true position. This is particulary the case when the Fram was stopped 

 by the ice, and the weather made it impossible to obtain observations of 

 the sun, for instance, in 1898 in Melville Bay, from the 7'*' to the 13"" 

 August, and in 1900, in the Belcher Channel from the 26"^ August to 

 the 17"^ September.
