88 GEOLOGY. 



The Swedish and Russian series correspond. The Swedish Dictyo- 

 nema Schists pass down into the Olenus Schists (= Lingula Flags), than 

 which the corresponding Russian beds cannot be newer. W. H. D.

From a private report to Prof. Delesse. Give measurements and 

 details respecting a boring of more than 540 metres. The object was 

 a search for petroleum ; but the bore led to the discovery of large deposits 

 of salt in the Middle Keuper. G. A. L.

at Lisieux.] Hev. Geol. in Ann. Mines, ser. 7, t. x. p. 583. 

 The formations bored through are : — Soil, Corallian limestone, white 

 sand (with water), marl, Oxfordian clay.

This locality is on the left bank of the Arve, at its confluence with 



the Rhone. The steep bank shows a section (from below upwards) as 



follows : — Clay with fossil wood, old pebbly alluvium, intercalated sheet 



of glacial mud, old alluvium again, second and general sheet of glacial 



mud, stratified clayey loam. These facts are explained, not by the 



assumption of two glacial epochs, but by the advancing and receding 



phases of glaciers in Quaternary as in modern times. The old alluvia 



were deposited in advance of the glaciers by great rivers issuing from 



them. G. A. L.

 Resume of the author's views respecting the physical history of that 

 portion of the Alps. Explains the fan-shaped structure of the Mt. 

 Blanc group by lateral pressure. Believes the bedded gneiss and pro- 

 togine granite of parts of the district to have been originally deposited 

 horizontally as sedimentary rocks. G. A. L.
