The shale {N:o 126) is a black shale with straight cleavage, con- 

 taining a fairly great amount of combustible matter, and some per- 

 centage of carbonate of lime. Of organic remains there was only 

 one object, 2 mm. in size, which is possibly a fish-vertebra, and 

 there is nothing to tell us with certitude if this is a marine or a 

 terrestrial deposit. 



The sandstone (N:o 101) is light-gray in colour, does not efferv- 

 esce on the addition of hydrochloric acid, very much resembles 

 other light sandstones within the district and, like these, seems to 

 be formed of the products of degradation of a granite. As mentioned 

 before, this sandstone is the highest stratum reached in these sections. 



Here, in Ingolfs Fjord, consequently, there have been measured 

 profiles which, as will be seen by what has already been stated, 

 represent a series of strata of at least 200 metres. This series very 

 much resembles that which was observed in the sections at Hekla 

 Sound, and the transgression of the marine Carboniferous deposits 

 has, here too, progressed in several stages, and oscillations in the 

 sea-level have led to the alternate deposition of the fossiliferous lime- 

 stone series and the sandstone deposits. The analogy between the 

 profiles becomes all the more striking if we take into consideration 

 that, here, in Ingolfs Fjord too, there is, farther to the east, a profile 

 which, in a predominant degree consists of the limestones in the 

 Cape Jungersen section, of which a more detailed account Avill be 

 given below. 



The Cape Jungersen Section. 



This section has been measured in a mountain on the south 

 coast of Amdrup's Land, at the mouth of Ingolfs Fjord, east of the 

 two river profiles that have just been described. If close attention 

 be paid to the map PI. XXX, there will be found given there as 

 the promontory forming the southernmost extremity of Amdrup's 

 Land, Cape Jungersen, and, directly westwards of this name, two 

 mountain tops, the most westerlj^ 510 metres, and the easternmost 

 400 metres in height. It is impossible to decide with certainty from 

 which of these tops the collection designated as the Cape Jungersen 

 section has been obtained. From Wegener's sketch-map I am most 

 inclined to take the western height, but, on the other hand, he 

 mentions in his notes that the rocks of which the top consists, have 

 been taken from a height of between 300 and 400 metres. 



Captain Koch has kindly communicated to me that Cape Jun- 

 gersen is the whole mountain and that the fossils were collected by
