586 KRAUS, DRIFT-WOOD OF EAST GREENLAND. 



GVI.— Drift-wood of East-Arctic Greenland. From 

 the Memoir by Dr. Gregor Kraus, in " Die zweite 

 deutsche Nordpolarfahrt/' vol. ii., pp. 97-132. 1874. 



Of the 25 pieces of Drift-wood and two small pieces of Bark, 

 submitted to the Author, one specimen was found in the K.-Franz- 

 Joseph Fjord, and the others near the Pendulum Islands. He 

 submitted them to an exhaustive botanical examination. 



Twenty-t"wo of the 25 Woods were Coniferous four certainly 

 belonging to Larch {Larix sibirica, Lederb. ?), and probably 

 13 others; and 5 to Larix Sibirica, Led., or Picea obovata, Led., 

 probably the latter. Of the two bits of Bark one belongs to Larch, 

 and the other possibly to Picea excelsa. Of three remaining 

 specimens, two are Alder, possibly Alnus incana^ L. ; and one 

 probably Populus tremula, L. 



That Siberia is the source of the E. -Greenland Drift-wood, as 

 it is (according to Agardh) of that of Spitzbergen, Dr. Kraus 

 regards as very probable. He adds his opinion, moreover, that 

 there is strong support for Grisebach's hypothesis, that the Flora 

 migrated from Siberia, by Novaya Zemlya and Spitzbergen, to 

 Greenland and Iceland, in succession.

Dr. Toula reported that the geological and palseontological 

 specimens collected in East Greenland, between 73° and 76° N. lat., 

 by Lieut. Julius Payer and Dr. Copeland, had been examined 

 by Dr. F. Lenz and Dr. Fr. Toula, under the superintend- 

 ence of Prof. F. von Hochstetter. Sabine, Pendulum, and Kuhn 

 Islands were best represented in this collection. The whole 

 continent of Greenland, between 73° and 76° N. lat., constitutes
