12. " Notes on some recent Discoveries of Copper-ore in Nova 

 Scotia." By Edwin Gilpin, Esq., M.A., E.G.S. 



The author described the occurrence in the northern part of 

 Nova Scotia of a great band of Silurian deposits, running nearly 

 east and west, and traversed in a corresponding direction by nume- 

 rous detached bands of granites, syenites, &c. Eoughly parallel to 

 the line of the latter there is a tolerably well-defined series of 

 fractures running from Parrsboro on the Bay of Eundy to Guysboro 

 on the Atlantic coast. The course of this line of disturbance is 

 marked by metamorphism, and by the presence of associated ores of 

 iron and copper. The principal localities where the latter occur 

 are noticed by the author, who states that the copper deposits 

 attain their greatest development near Lochaber Lake and Poison's 

 Lake, where they form a series of veins cutting at oblique angles 

 black and red shales and quartzites, apparently of somewhat doubtful 

 age. The quality of the ore is said to be good. 



13. " Glacial Drift in the North-eastern Carpathians." By E. L. 

 Jack, Esq., E.G.S., and John Home, Esq., E.G.S., of the Geological 

 Survey of Scotland. 



In this paper the authors noticed the statements of previous 

 observers as to the occurrence of glacial drift in the northern part 

 of the Carpathian range, and described the rock-formations sur- 

 roundiug the head- waters of the Theiss, and some drift sections 

 observed in the valley of that river. They arrived at the following 

 conclusions : — Glacial deposits are not abundantly developed in the 

 valleys of the north-eastern Carpathian. The drift in the upper 

 reaches of the Theiss is of the most fragmentary character, and is 

 confined mainly to the broader portions of the valley. There is, 

 however, sufficient evidence for maintaining that the Theiss valley 

 was filled with a glacier upwards of 45 miles long, although the 

 authors were unable to determine whether this glacier ever debouched 

 on the plains of Hungary or ever reached the edge of the Carpathian 

 chain ; but they think it probable that such was the case.
