Occurrence of the plant-fossils. 



The discovery of a carboniferous flora in the area between 80 

 and 81 degrees of northern latitude on the east coast of Green- 

 land is of special interest from a palaeobotanical point of view. 

 This flora represents the most northern carboniferous flora hitherto 

 known, the corresponding plant-bearing deposits of Spitsbergen 

 being all situated south of the 80th degree. In consequence of the 

 circumstances — long sledge-journeys — during which the materials 

 were collected the collection is naturally not comprehensive: never- 

 theless it contains specimens of interest. It certainly also promises 

 rich harvests in the future if the deposits in question are examined 

 with the chief object of gathering fossil plants.

As to the geological position of the plant-bearing strata Mr. 

 H. Jarner, the geologist of the expedition, has sent me the following 

 communication, regarding which, however, it ought to be mentioned 

 that Mr. Jarner has not seen any of the carboniferous localities 

 himself but owes his information to Messrs Koch and Wegener, 

 the former of whom has travelled along the outer coast, while Mr. 

 Wegener visited Hecla Sound and Ingolf Fjord. 



The carboniferous deposits occur on the coast outside the Ar- 

 chaean rocks. They here form a plateau, the height of which at 

 the outer coast measures about 500 meters, while it is somewhat
