of Brorup in southermost Ju tland, e. g. Bvasenia purpurea, Cav- 

 pinus beiidus, Dulichium spathaceum and Picea excelsa. — In the 

 present paper mentioned more interesting localities are from the 

 southern Jutland as well as a few Irom the Danish islands. 

 Commonly there is a flat, bowl-shaped depression in the soil surface 

 over the interglacial bog-bassin, the peat in course of time becoming 

 strongly compressed under the weight of the over-lying diluvial 

 layers. In the Brerup deposits these layers reaeh a thickness of 

 5 m. and are composed of sand with a few stones; these overlying 

 sand layers the author considers as stratigraphical evidence for the 

 interglacial age of th fossiliferous beds, and by anatysing their fiora 

 and manner of deposition he brings about a palaeolontological evi- 

 dence herefore. The characterizing plants are Picea excelsa and 

 Carpinns betulus, both of which are not known from postglacial bogs 

 in Den mark. It is however not merely the occurrence of these 

 species and the occurrence of Hex, Taxis, Tilia grandifolia and Vis- 

 cum — also not known from our postglacial bogs — , which prove 

 that the bog is interglacial; but only by this conception we can 

 obtain a natural explanation of the distribution of the species 

 in the different layers of the bog. In a list of the trees and bushes 

 found in the bog the author has arranged the plants in the order, 

 in which they first appear (have come to) the bog. From this it 

 appears: 



1° that the species occuring last in the series of layers [Hex, 

 Taxus, Tilia) disappear earliest — in other words are only found in 

 the intermediate parts of the bog, which correspound to the tempe- 

 rature maximum of the interglacial period. 



2° that the consecutive order in the table in the whole agrees 

 with the geographical distribution of these plant species in the 

 present time, in this way that those named first in the table go 

 furthest to the north, while the species mentioned last in the table 

 disappear at a more southern latitude. 



3° that the common species have come to the bog in the same 

 order, in which the same plants settled down in our postglacial bogs.

From a palaeobotanical point of view the discovery of a carbo- 

 niferous fiora in the area between 80° and 81° N. L. on the east 

 coast of Greenland is of a great interest: the fossils found repre- 

 sent namely the most northern carboniferous fiora hitherto known. 

 The deposits occur on the coast around „Ingolfs Fjord" outside 

 the Archaean rocks and form a plateau about 500 m. in height. In 

 a section figured the following strata were found: Shale conglome- 

 rate, sandstone and limestone, the two last being fossiliferous. The 

 stratigraphical position is analogous to that of the plant-bearing 

 carboniferous beds of Spits bergen, the age of which is lower 

 carboniferous. This is also the case with these deposits. 



Besides some rachises of ferns (or pteridosperms), which could 

 not he determined with any accuracy, the following species were 

 identified:
