granite. Wegener says of it: ''Es waren nur sehr undeutliche Spuren 

 von FossiHen in dieser Schicht zu sehen (Kriechspuren)". 



At 200 metres above the sea there was exposed a peculiar series 

 of strata, of which Wegener speaks as follows: "200 m. sehr dunk- 

 ler schwarzer Kalk (violetter Ton) mit zahlreichen deutlichen Fos- 

 silien, auch Muscheln. Mit 4 schiefrigen oder erdigen, mit dem 

 Messer spaltbaren Zwischenlagen (je 1 dem. dick). Die 3 obersten 

 wimmeln von Muscheln". This bituminous limestone with inter- 

 mediate marl-shale partings is probably the same stratum as that 

 in this profile at 175 metres above sea-level; and that in Koch's sect- 

 ion at 240 metres above the sea; the fossil-contents confirm the 

 relationship with the bed in question in Koch's profile. The "Mu- 

 scheln" mentioned by Wegener are certainly brachiopods; in the 

 specimens {N:os 190 and 192) obtained from this locality, there are 

 5 specimens of Spirifer supramosquensis Nik., 3 specimens of Spirifer 

 rectanguliis Кит., var. alla п. var., 1 specimen of Productus simensis 

 TscHERN., 1 specimen of Chonetella nasuta Waag. and some few 

 rugose corals. Both the harder limeslone and the alternating marly 

 beds are highly bituminous, but, on heating, become of a gray-yel- 

 lowish colour; in consequence of weathering they have, on the sur- 

 face, obtained a gray-green tinge. The limestone contains a large 

 number of small crinoid stems, and, under the microscope it shows, 

 in an almost close-grained matrix a number of fossil-fragments of 

 calcite, with fragments of crinoids and bryozoa a few brachiopod 

 spines and Fusiilince. 



This bituminous limestone, of the thickness of which no state- 

 ment is made, is underlaid by a sandstone (N:o 177), of which, 

 however, only one layer, 1 decimetre in thickness, was observed. 

 The rock was friable and not very compact; it was brown in colour, 

 rich in mica and finely bedded. The rock overlying the bituminous 

 limestone consists immediately of sandstone, of which Wegener says 

 in his notes: "Probe aus dem Geröll unmittelbar über dem vorigen 

 = grüner Sandstein, offenbar unmittelbar über dem Kalk in 20 m. 

 dicker Lage anstehend (was wenig mehr östlich zu sehen warj. Dann 

 kommen wieder helle und violette Kalke mit dunkelroten Bändern 

 von Conglomerate oder Sandstein wechselnd. Anscheinend vorherr- 

 schend Kalk bis zum Gipfel". 



The specimen of this green sandstone {N:o 187), which is a loose 

 piece weathered out from the rock-wall, and collected in the talus 

 greatly resembles the sandstone found at 190 m. above the sea and, 

 like the latter, is somewhat calcareous. 



To judge by Wegener's notes, his ascent of the Mallemukfjæld
