Wernerian Societt/, 



-O-T the meeting of this society on the .22d of February Mineralogy of 

 a communication from the Rev. Mr. Fleming of Fliak, was^"^^"^'^°^ 

 read, describing the mincralogical appearances, which oc- 

 cur on the north bank of the Frith of Tay, from Dutulce 

 up to Kingoodie quarry. The rocks are clajstone, 

 claystone-porphyry, felspar-porphyry, greenstone, sand- 

 stone and amygdaloid. The sandstone occurs in basin- 

 shaped cavities in the porphyry, and contains subordinate 

 beds of greenstone; but he deferred giving any decided opi- 

 nion concerning the igeognostic relations of these rocks, 

 till he should examine the south shore of the Frith of Tay. 



At the same meeting, the secretary read a communication andof tTie 

 from Mr. Macgrcgor, surgeon to the 25th regiment, giving i°,nark. '^'^"" 

 an account of the mineralogy of the country around the 

 town of Lanark, particularly at the celebrated falls of 

 Cora Lin and Stouebyres. Near the former, porphyry- 

 slate and felspar-porphyry occur. At the latter, the 

 waters are poured over beds of fine grained sandstone, 

 •which, in descending, gradually becomes coarser in (cxturej 

 till it passes into a conglomerate, consisting of masses of 

 quartz, jasper, splintery hornstone, flinty-slate, and clay- 

 slate. Near Nethan bridge, the traces of a coal dcposi- " 

 tion and a portion of a coal-field make their appearance ^ 

 many alternating beds of sandstone, bituminous shale, and ^ 

 clay ironstone occurring along with thin beds of slate coal 

 and cannel coal. Mr. MacgregOF stated it to be his opinion, 

 that the sandstone cxposeil on the banks of the Clyde and 

 of the Moose river near Lanark, belongs to one and the 

 same formation ; that the Mouse has gradually scooped out 

 the present channel, in the same way as the Clyde is sup- 

 posed to have done; and that there are here no marks of 

 any violent convulsion of nature, as some have imagined. 



An extract of a letter from Lieutenant Huey of the 73rd Large sea 

 regiment was also read, mentioning the circumstance of a^"*^°* 

 large marine animal, supposed to be about thirty feet long, 

 and shaped like a snake, having been observed from a ship 

 ialat. SS*' 13 S. and long, b'' E.
