sented in the section to the ‘ Ell’ and other well-known seams in the 
neighbourhood. 
Mr. J. Rerp read a paper On Continuous Internal, Vertical, and 
Horizontal Movements in the Earth’s Crust, referring to cracks, 
joints, ‘ slickensides,’ ‘lypes,’ and ‘lunkers’ in the Coal-measures as 
evidence ; and regarding the ‘underclays ’ as being material of conti- 
guous beds ground down by pressure. The ‘ waves without wind’ in 
Lochs Lomond and Tay, the apparently causeless tremulousness of 
water and leaves, cracking of walls, shrinking of lintels in houses, 
the giving way of embankments, &c., were also referred to as being 
often the results of internal movements of the earth’s crust. 
Mr. R. Sxipsey read a paper On some of the Trap-rocks and 
Minerals of the Cathkin Hills, of igneous origin, ranging east and 
west a little south from Rutherglen. ‘The quarries opened about 
the middle of the range exhibit many varieties of igneous rock, and 
the minerals usually accompanying such. These consist of columnar 
and amorphous basalt, several varieties of greenstone and por- 
phyries. Among the minerals are heliotrope or green jasper, 
amethyst, rock-crystal, calcareous spar, and deep-green talcose 
chlorite. Several varieties of the rocks are very fine, the columnar 
basalt especially, being a mass of beautiful columns at present laid 
open to a depth of 30 feet, but going downwards about 80 more. 
They are as perfect in form as those of Staffa and the Giant’s Cause- 
way, and are from two to three feet diameter, the prisms being four- 
and five-sided, and in several other parts of the hills the form is 
equally perfect. The tops of the columns exhibit a fine illustration 
of the effects of the Boulder-drift, the groovings of which are 
remarkably regular. 
It is a matter of deep regret to geologists and admirers of natural 
scenery to see these fine monuments of antiquity destroyed, even for 
the useful purpose of keeping the roads in repair, and it would be 
no great sacrifice to the proprietor to leave some portion of these 
majestic columns of basalt standing. 
Mr. Jonn Dennison exhibited a vertical section, 16 feet long, of 
all the various geological formations, with a centre column of coloured 
drawings of fossil organisms; showing at a glance the order, com- 
position, the minerals, metallic ores, and characteristic fossils of 
each formation. This section, drawn by Mr. A. Dennison, Edin- 
burgh, was much admired for the artistic excellence of its execution 
and design. 
Norwicu GronocicaLt Society; in connection with the Norfolk 
and Norwich Museum.—On January 3rd the usval monthly meeting 
was held, the Rev. John Gunn, F.G.S., President, in the chair. 
The discussion on the specific differences between V'rogontherium 
Cuvieri, the Beaver of the Cambridgeshire Fens, and the recent 
Beaver, was resumed by Mr. Harper. Some fine remains of the 
Beaver from the Fens, and a magnificent tusk of Trogontherium 
from the Norwich Crag, were produced by Mr. Robert Fitch, F.G.S. 
Mr. Harper observed that there was a decrease in the size of the 
tusks from the Trogontherium to the Fen specimens, and equally so
