8. Conglomerate limestone, which forms the greater part of the 

 environs of Theodosia. 



9. Magnesian limestone, constituting the highest mountains of the 

 Crimea. Near Koutlak it rises above ail the other formations, having 

 very elevated and isolated cupolas and rounded summits. The flanks 

 of the mountains are generally steep, and often perpendicular, as is 

 well seen at the Falkenberg near 8oudagh, and in the mountain chain 

 ofYaila. 



10. Red sandstone conglomerate, the component parts of which vary 

 from very small grains to blocks of six feet in diameter. It lies under 

 the magnesian limestone, and is found in very large masses at Koos. 

 Fragments of quartz, flinty slate, limestone, slate-clay, greenstone, 

 and sandstone are contained in it. 



11. Quartzy sandstone found at Nikita. The author suspects 

 that this rock was mistaken by Pallas for the old red sandstone. It 

 is always more or less interstratified with wood-coal, 



12. Slate-clay, which begins behind Koutlak, on the road from 

 Kapsiter, and ranges towards Gouak, Koutschouk Kousin, and Kou- 

 rousin on the road from Alouschta. Tliroughout its whole extent, 

 the author found it to contain alum, derived from decomposing pyrites. 

 This slate-clay also contains a considerable bed of wood-coal, and 

 masses of clay-ironstone. 



13. Basalt, occurring only in beds of inconsiderable thickness 

 and small extent, as at Sably and Kikineis ; also near Kozloff, Se- 

 bastopol and Theodosia. 



14. Greenstone, which occurs on Mount Aioudagh nearKoutschouk- 

 Lambat. The serpentine described by Pallas was merely decomposed 

 greenstone. 



15. Wacke, accompanied with basaltic hornblende and crystals of 

 black mica, occurs in the greenstone just mentioned. 



16. Amygdaloidal basalt, greenstone, and wacke. These rocks 

 are met with near the convent of St. George, oh the sea-shore. 



17. Argillaceous or clay-stone porphyry, remarkable for its columnar 

 appearance, occurs above Alma, three wersts above Sably. 



Feb. 1. — A paper was read "On the deposits overlying the car- 

 boniferous series in the valley of the Eden, and on the north-western 

 coasts of Cumberland and Lancashire," by the Rev. A. Sedgwick, 

 F.G.S. F.R.S., Woodwardian Professor in the University of Cam- 

 bridge, &c. 



The author states that this paper is a continuation of two former 

 communications *, and that the details, now laid before the Society, 

 define the geographical limits of the central Cumbrian Mountains ; 

 a general description of which will form his next object. 



§ 1. He first traces the geographical distribution of the new red 

 sandstone series, which commencing near Kirkby Stephen is ex- 

 panded, between the central Cumbrian chain and the carboniferous 

 chain of Cross Fell, to the Solvray Firth. lie then traces the mem- 

 bers of the same series along the north-western coasts of Cumber- 

 land and Low-Furness; pointing out their modifications of structure
