 like the nearest neighbouring sand and clay beds, always contains 

 remains of leaves, which may then either form small separate layers

or an isolated nodule in the sand of some few inches diameter ; 

 whereas it would be vain to look for impressions of leaves in the 

 more distant sand-beds. Coal strata worth working probably do 

 not occur in this horizon of the Miocene ; at least the layers at Atane, 

 the largest coal-beds at Kome, and at Ipiit near Kudliset, seem to 

 lelong to the Upper Cretaceous, while the strata at Netluarsak, Isorisok, 

 the coal in the high fells at Skandsen and Assakak, belong to the 

 middle, not the lower horizon, of the Miocene of Greenland. Probably 

 also the coal-beds at Hare Island do not belong to this formation, as I 

 have already observed.^ 



From the Lower Miocene strata at Disko Isle we collected fossils 



1 Dr. Nauckhoff's and Dr. Pfaff's discovery of Sigillaria makes it possible that 

 the Coal strata of the Coal formation occur at IJjavasusuk.
