but has added to the latter some details from the Conglomerate 

 section. In addition it should be pointed out that a more detailed 

 examination of the rocks shows other results than those given in 

 the notes made by Jarner after the first cursory determination made 

 on the spot and entered in the diaries.

gray limestone, alternating with black

view of the finds at Hekla Sound 

 show that Jarner's profile is, in a high degree, generalized, and in 

 part must be modified. It should first of all be pointed out that 

 the thickness, as given, of the conglomerate cannot be controlled or 

 confirmed by the collections or by the notes that I have available 

 (Wegener states — see above — thai the conglomerate alternates 

 with a light limestone). Secondly, Jarner's series of strata, 200 — 

 275 m. of sandstone, must be interpreted as a series of a partly bitu- 

 minous limestone alternating with layers of shales and sandstones of 

 various character. The series of strata from 200 to 275 m. in Koch's 

 Section probably corresponds to the series 150—220 m. in the Con- 

 glomerate Section, the bituminous rocks, especially, show such a 

 great agreement in regard to their fossils that a correlation can by 

 no means be considered as bold (the distance between these two 

 sections is not so very great, a few hundred metres, but unfortun- 

 ately it is not known with exactness; in accordance with this 

 combination of the series of strata, the deposits at the Conglo-
