strata. The red sandstone at Ballochmoyle lies in wedge-shaped 

 masses in the conglomerate (fig. 1), like the same deposits at Belah, 

 Westhouse, and Flookborough (Humphrey Head). 



The conglomerate and breccia, whether seen at Flookborough in 

 Furness, Westhouse in Yorkshire, Belah Bridge and other places in 

 Westmoreland, near Dumfries, at the foot of Criffel near the mouth 

 of the Nith, or at Ballochmoyle in Ayrshire, present the same kind of 

 paste or cement, resembling decomposed felspar, but the imbedded 

 rocks vary as the rocks of the respective districts do ; thus at Flook- 

 borough, Westhouse, Belah, and Brough, we have limestone frag- 

 ments, — at Craigs and in the Cleuden, slates and Silurian rocks, — 

 near Criffel, granite, — and at Ballochmoyle, trap ; clearly showing 

 that such rocks have been derived from the beds of the neighbouring 

 districts, and not brought from a distance. 



The circumstance of the large tract of the South-west of Scotland, 

 hitherto coloured as Trias, proving to be Permian, must be of great 

 importance to the ironstone and coal districts lying near it, and will 

 in some instances no doubt allow such deposits to be followed under 

 it. In addition to this economical advantage, the change cannot 

 but prove highly interesting to the palaeontologist, as it will enable 

 him to remove all the tracks of animals found in the Corncockle 

 Muir, Locker Bridge, Craigs, and Greenbank quarries from the 

 Trias and place them in the Permian fauna, — a position where they 

 will better fit, when compared with the continental deposits, than in 

 their old place in the Trias.

The following Communications were read : — 



1. On the Cryolite o/Evigtok, Greenland. 

 By J. W. Tayler, Esq. 



[Communicated by J. Tennant, Esq., F.G.S.] 



The few remarks which I am about to offer relate to the mineral 

 Cryolite*, and the nature of the district in which it occurs; and I 

 propose to lay before the Society some observations which the ex- 

 ploration of a rich lead-vein situated in the Cryolite has afforded me 

 the opportunity of making. 



Evigtok (which signifies in the Esquimaux language " a place 

 where there is plenty") is distant about twelve miles from the Danish 

 settlement of Arksut, and forms a small bay in the Fiord of Arksut ;
