vailing rocks are reddish sandstones, shales, and clays, with some 

 grey beds ; conglomerates, especially in lower part ; and subordinate 

 to these, thick beds of limestone, thick beds of gypsum with anhydrite. 

 Thickness, 6000 feet or more. 



Fossils. — Calamites, fragments of Carbonized plants, Producta, 

 Terebrattda, Encrinites, Madrepores, Sfc. 



Small quantities of copper ores are found in the sandstones in the 

 gypsiferous and newer coal formations, especially in the latter. Salt 

 springs rise from the older coal and gypsiferous formations in a few 

 places. Veins of hematitic iron ore occur in the gypsiferous rocks 

 of the East River. The strata of the two older membei's of the 

 carboniferous system are more hardened and disturbed than the 

 newer series, and contain beds of trap, which occur in no part of the 

 newer coal formation, except the conglomerate at its base. — J. 

 Dawson, Esquire. — Proceedings of the Geological Society, January

3. Sur les Lignes d'Anclen Niveau de la Mer dans le Finmark. 

 Par M. A. Bravais, Membre de la Commission Scientifique du Nord. 

 M. Bravais, one of the distinguished naturalists of the French Scientific Com- 

 mission to the North, gives in this memoir a minute, accurate, and interesting 



* Mr Dawson remarks, that the greater part of the rocks composing 

 the newer coal formation of Pictou were formerly confounded, under the 

 name of new red sandstone, with a part of the gypsiferous series, 

 and with a deposit of non-fossiliferous red sandstone skirting the 

 shores of the Bay of Funday, and unconformably superimposed on the 

 older carboniferous strata. He adds, " I have no doubt, however, that 

 in other parts of Nova Scotia the newer coal formation will be found to bo 

 a well-marked carboniferous group."
