is true to some extent of the observations taken in the course 

 of the journey at a few other arctic and subarctic spots, namely, 

 on Jan Mayen and in the NW. territory of Iceland between 

 Dyrafjord and Önundarfjord, observations which are referred to 

 here only in so far as they supply further knowledge of phe- 

 nomena investigated in Greenland. 



The mapping-out of the first-named territory, begun by 

 Ryder and continued by Nathorst, was proceeded with during 

 the recent expedition and completed in its main features; I 

 may, therefore, refer in this place to the maps that have now 

 appeared. The best maps of the more northerly stretches of 

 coasts will be found in the account of the Second German 

 North Polar Expedition^), Up to the present time we are in- 

 debted, for our knowledge of the geological formation of the 

 district in question and of the contiguous tracts, to the ex- 

 peditions mentioned below ^). Geological maps of different lo-
