WERNER IAN SOCIEXy. 



On Saturday, the 5th of Marcii, there was read an interesting 

 paper on tlie middle granite district of Galloway, by Dr. Grierson. 

 It appears, from the Doctor's observations, that this granite extends 

 from eight to nine miles in one direction, and from three to four in 

 another. It is coarse granular, sometimes porphyritic, but does not 

 appear to be stratified. It is situate in the midst of distinctly stra- 

 tified rocks, which on the east side of the granite mass dip easterly, 

 on the west side westerly, or in both cases away from the granite ; 

 out on the north and south ends of the mass, the ends of the strata 

 run directly towards it. The rock which rests immediately on the 

 granite is a particular variety of compact fine granular gneiss, and 

 cotemporaneous veins of the granhe are to be observed shooting 

 from the granite into this variety of gneiss. The gneiss seems to 

 be connected with greywacke and grey wacke slate, which are by far 

 the most frequent of the stratified rocks in this tract of country. 

 Limestone, hitherto a desideratum in the transition rocks of Gal- 

 loway, was discovered by Dr. Grierson, in greywacke, near to 

 Dalmellington ; and it is highly probable that ivorhable beds of 

 limestone will be found among the stratified transition rocks of 

 Galloway. The Doctor also described several beds of felspar- 

 porphyry, which he noticed in the greywacke of this part of 

 Scotland.* 



At the next meeting, Professor Jameson gave an account of over- 

 lying primitive formations, as the first part of a dissertation on
