 Scania.] Geol. foren. Stockholm Fdrhandl. bdt. i. pp. 281-294. 



Further proofs are given that a sinking no longer takes place in 

 Scania, but that, on the contrary, this province shares in the general 

 elevation of Scandinavia, and that the line of demarcation of this 

 movement consequently runs to the south of Scania. E. E. 



Naumann, Dr. C. F. Ueber die Hohburger Porphyrberge in Sachsen. 

 [Hohburg Mountains, Saxony.] N. Jahrb. Heft iv. pp. 337-361, 

 with map. 



A description of the smooth, polished, and striated surfaces on the 

 porphyry-rocks forming the Hohburg and other hills near Wurzen in 

 Saxony, and a review of the causes which have been suggested to 

 account for the formation of these surfaces, such as the action of blown 

 sand and ice-action. Prof. Naumann's last memoir, left unfinished at 

 his death. F. W. K.

 [Phosphatic deposits of Ciply.] Compt. Kend. t. Ixxix. pp. 256 

 -259. 



These deposits are in the Upper Chalk. They form a kind of con- 

 glomerate of brownish nodules, cemented in a calcareous paste and 

 associated fragments of indurated chalk and fossils, the latter being 

 sometimes rolled ; the thickness varies, but rarely exceeds 1*5 metre. 

 Several analyses are given. G. A. L. 



NoGUES, A. F. Les oscillations de la mer nummulitique. [Oscilla- 

 tions of the Nummulitic Sea.] Compt. Rend. 2 sess. Assoc. 

 Frang. pp. 409-433. 



After an account of the distribution of the various members of the 

 Nummulitic series, the writer concludes : — 1. That the lowest Nummu- 

 litic beds of India and of the Pyrenees seem to be anterior to the Sues- 

 sonian beds of the Anglo- Parisian Basin. 2. That the lowest Nummu- 

 litic beds of the Adour Basin appear to be contemporaneous with the 

 middle beds of the Pyrenaoo-Mediterranean Basin ; and that, moreover, 

 the Adour Basin possesses a Nummulitic horizon of Tongrian age, 

 This basin was dry land when the central Pyrenees, the Corbieres, and 

 India were covered by the waters of the great Lower Nummulitic 

 lake. 3. That the Nummulitic beds of the Maritime Alps and of the 

 Var are contemporaneous with those of the Central Pyrenees; but 

 those of the Central Alps of Switzerland and Savoy seem to correspond 

 to the Middle beds of the Pyrenees and to those of the Adour Basin.
