grey splintery limestone, and slate-coal, caractérise tins in- 

 teresting series of rocks as belonging to a coal formation. On 

 comparing the individual characters and general relations of 

 these rocks, there can be no doubt of their belonging to that 

 coal formation, in which all our principal British coalmines are 

 situated, namely the Great Coal Formation, which lies 

 upon old red sandstone and mountain limestone, and is covered 

 in the regular series by magnesian limestone and new red 

 sandstone». 



Fra Cap Brewster omtales bl. a. Brunkul og hertil knyttes 

 følgende Bemærkninger: «The brown coal would seem to shew, 

 that the trap-rocks here are probably associated with a new 

 limestone or sandstone formation , and not with the coal for- 

 mation , such as that of Jamesons Land , which does not con- 

 tain true brown coal.» 



I Afsnittet «General Remarks» udtaler Jameson følgende 

 om de Forhold, der interessere os her: «The secondary rocks, 

 as appears from the preceeding enumeration, seem to be distri- 

 buted into at least two formations, viz. the Coal Formation, 

 and the Secondary Trap and Porphyry Formation. 



I. Coal Formation. — Giesecke does not mention the 

 coal formation, and therefore it is now for the first time enu- 

 merated amongst the rock formations of Greenland. It exhibits 

 the same characters in Greenland as in Europe, and other quar- 

 ters of the globe, and its prevalence in Jamesons Land is that 

 which gives this great tract of country its peculiar characters, 

 thus affording another example of the connection of the general 

 and particular forms of the surface of a country, with its 

 geognostical structure and composition. From this series of 

 rocks always containing numerous remains, more or less mine- 

 ralised, of plants, many of which have a tropical aspect, its 

 occurence in this high northern latitude, in this region of snow 

 and ice, becomes particularly interesting. The coal formation
