 an der Westkiiste Spitzbergens. Min. Mitt. Heft iii. pp. 181-198 ; 

 Heft iv. pp. 261-268, 9 woodcuts (sections &c.). 

 Observations on the rocks of the west coast of Spitzbergen, between 

 Bel Sound and Amsterdam Island. The first paper gives a list of geo- 

 logical writings on Spitzbergen ; then describes the occurrence of gneiss, 

 granite, and crystalline slates ; and afterwards that of the sedimentary 

 rocks, including the Hecla-Hook formation, the Carboniferous Lime- 

 stone, and the Trias. The second paper describes the diabases of Spitz- 

 bergen, gives original analyses of them, and notes the occurrence of 

 sedimentary rocks of Jurassic, Cretaceous, and Tertiary age. F. W. R.

 upheaval of the North Polar regions.] 

 Maintains that the old Dutch maps representing many of the pro- 

 montories of the Spitzbergen mainland as islands were correct, and that 

 a measure of the rate of emergence of the land is thus afforded. In 

 1594 a sandbank, 18 fathoms below the surface, alone marked the pre- 

 sent Gulf-stream islands east of Cape Nassau. In this case the upheaval 

 has been at the rate of 30 metres in less than 300 years. G. A. L.

 A record of the geological observations made during Count Wilczek's 

 north-polar expedition. The paper is under three heads : — 1. General ; 

 2. On the structure of Spitzbergen, especially in the Horn-Sound region, 

 with much stratigraphical and lithological information ; 3. On glaciers,
