590 TOULA ON THE GEOLOGY OF EAST GREENLAND. 



2. Hochstetter's Promontory. Coal and sandstone without 



plant-remains. 



3. Sabine Island. In shales and sandstones on the east 



slopes of Hasenberg and Germaniaberg, both about 

 74J° N. lat. 



Taxodium distichum miocasnum, Hr., the most abun- 

 dant fossil plant in Sabine Island. 



Populus arctica, Hr. 



Diospyros brachysepala, Al. Br. 



Celastrus, sp. 



These are of Miocene age, and belong to a plant-bearing forma- 

 tion like that in W. Greenland and Spitzbergen. Of the four 

 species above mentioned, three are found also in W. Greenland. 

 Prof. Heee remarks (p. 515), ^'1 have stated in my * Miocene Flora 

 " * of Spitzbergen ' that Spitzbergen has 25 species of Miocene 

 '' plants in common with W. Greenland ; and I have mentioned 

 " these species in particular, Taxodium distichum, Sequoia 

 " hrevifolia, Populus arctica, P. Richardsoni, P. Zaddachi, 

 " Corylus MacquaiiH, Quercus platania, Q, Grceiilandica, Pla- 

 " tanus aceroides, Andromeda protogcea. Viburnum Jfhymperi, 

 " Cornus hypcrbo^'ea, Hedera Macclurii, Rhamnus Eridani, 

 " Paliurus Colombi, and Nordenskiceldia borealis. As these 

 '' species had been found in W. Greenland at 70° N. lat., and 

 " in Spitzbergen at 78°, I remarked that very probably they once 

 " spread over a great intermediate land and the whole of North 

 " Greenland, and that they would be found in the Tertiary beds 

 " of East Greenland (Heer's ^ Flora Spitsberg.,' p. 12). This anti- 

 " cipation has been fulfilled by the finding oiPopidus arctica and 

 " Taxodium distichum on Sabine Island, where probably further 

 " search would discover the other above-mentioned species. The 

 *' Tax. distichum is of the greatest interest, as it was certainly 

 " the most abundant tree in Miocene Spitzbergen and West 

 " Greenland, and exists still as far as the Southern States of 

 " North America." See above. Prof. Heer's later researches, 

 pp. 378, et seq.

Dr. K. Vrba describes the following, both as to constitution 

 and structure : — 



1. Gneiss from Illuidlek Island (Lat. 61° N., Long. 421° W.), 

 associated with a coarse-grained hornblendic gneissose 

 granite. It is fine and sometimes loosely grained mix- 

 ture of black-brown mica, yellowish-grey felspar, greyish 

 quartz, and some garnet.
