Proceedings of the Wernerian Society, 197 
Stonehaven, he described as belonging to the secondary class, 
and as consisting of red sandstone, with vast beds of conglo- 
merate and trap-rock, and smaller beds of limestone and clay - 
ironstone. These, as we advance towards Aberdeen, are suc- 
ceeded by strata of clay-slate, grey-wacke, mica-slate, and 
gneiss. In these strata, but particularly in the gneiss and mica- 
slate, are numerous veins, beds, and imbedded masses of gra- 
nite, also of porphyry, felspar, hornblende-rock, &c. 
Jan. 23. — Dr Hibbert read the first part of a geognostical 
description of the Shetland Islands, an abstract of which will 
be given in our next Number. 
Feb. 6, — At this meeting Professor Jameson continued 
the reading of his geognostical description of the Grampians. 
He gave an account of that portion of the Grampians which 
extends from Fettercairn across the Cairn-o-mount to the river 
Dee, and continued the section across the mountains by Tomen- 
toul to the Spey. The strata around Fettercairn are of red 
sandstone ; at the bottom of the Cairn-o-mount these are suc- 
ceeded by clay-slate, containing beds of limestone ; as we ascend 
the mount, mica-slate and gneiss take the place of the clay- 
slate, and these in their turn are succeeded by granite. The 
granite continues nearly to the inn of Cuttieshillock, on 
the north side of the range. Near Cuttieshillock inn, the 
gneiss again appears, and continues onward to the Dee ; in its 
course, including beds of limestone, hornblende-rock, and other 
members of the primitive series. From Charlestoun on the 
Dee, across the mountains to Tomentoul, the strata are gneiss, 
with vast beds of granite, also mica^slate, clay-slate, and quartz- 
rock, with beds and veins, and imbedded masses of granite, lime- 
stone, and of various primitive trap-rocks. The Professor de- 
scribed a particular formation of red sandstone near Tomentoul, 
and concluded by tracing the various primitive rocks, in this part 
of Scotland, down to the banks of the Spey. 
At the same meeting, the Secretary read a communication 
from Mr Sivright, respecting the frequent occurrence of glo- 
bules of air and water in topaz, rock-crystal, heavy-spar, and 
other minerals.
