 (d) contains no fossils, but from 240 to 275 meters (d") there is an 

 abundance of them, especially brachiopods. From 275 meters up

to its summit (probably 500 meters) the mountain is composed of 

 a dense limestone (e) rich in corals. 



According to the dip of the strata (fig. 3) the uppermost layers 

 at the Depot 80° 9' form the base of the Mallemukfjeld. That 

 mountain (about 500 meters high, fig. 4) also being built up of 

 limestone, the total thickness of this rock is estimated as at least 

 700 meters. 



No faults have been observed within the carboniferous formation.

From this communication of Mr. Jarner's it is evident that the 

 plant-bearing beds occupy the base of the carboniferous deposits of 

 N. E. Greenland, the whole formation being probably a downthrown 

 block outside the boundary-fault of the Archaean "Horst". Their
