This section was taken in a ravine opening into the centre of Kome 

 bay. The finest impressions af plants, however, occur in the 

 neighbourhood of the house-sites, not far from the limit of the 

 gneiss, which here forms a high mountain, immediately east of the 

 river (Kook), which on that side seems to form the limit to the 

 Lower Cretaceous beds of Greenland. 



Thick as the Lower Cretaceous strata are, they are now visible 

 only over a small area, as they only fill up the valleys between the 

 gneiss hills by the coast. The strata at Kome are separated by 

 gneiss hills from the strata at Pattorvik, and these again in the same 

 manner from those of Karsok, Angiarsuit, Avkrusak, and Ekkorfat. 

 The main mass of the formation, which evidently once extended 

 over Omenak Fjord, is now washed away. Whether it extended in- 

 ward into Noursoak peninsula under the basalt or not, it is im- 

 possible with certainty to say, as several of the deeper valleys are 

 filled with ice. I however think this extremely probable, although 

 the real Kome strata seem to be wanting at Atanekerdluk. They 

 may possibly reappear between the last-mentioned place and the 

 gneiss formation at Takkak. Calcareous strata are entirely absent 

 in the Creenland Cretaceous, and it is useless to look for marine 

 fossils there —everything shows that what we here have before us is 

 a fresh-water deposit. 



The fossils are most numerous and best preserved in the lowest 

 strata, and consist principally of ferns and Coniferee. Leaves of 

 Coniferfe and other plant-remains are also- met with, although rarely 

 in. the rpper strata; but those found there, in consequence of their 

 friability, can hardly be preserved. As regards these fossils, Prof. 

 Oswald Heer has made the following communication : —
