GENERAL. 
T he first meeting of the year was field on tfie evening of 
January 6tfi, when two papers were read by Professor 
Sollas, M.A., F.G.S.j F.R.S.E., tfie first being entitled A Visit 
to the Island of Torgfiatten in Norway.’’ This island had been 
visited by Professor Sollas in the previous July. It is remark- 
able in shape, resembling a conical hat with a broad brim, tfie 
latter corresponding to a table-land, which rises about 300 feet 
above tfie sea, and is surmounted by a peak reaching to a height 
of 900 feet. Nearly at the base of this eminence there is a 
natural tunnel extending right across it. It is 200 yards long 
and 20 in width. Professor Sollas attributed this remarkable 
formation to the action of rain, by which valleys had been 
excavated, leaving hills between them. Subsequently submersion 
occurred, and the chain of mountains produced the islands. As 
the sea continued its action, cliffs were formed leaving a plain, 
viz , the plain of marine denudation. In this manner the peak 
and table-land are accounted for. The tunnel owes its existence 
to two cracks extending down the side of the cone, between 
which we find the rocks, consisting of gneiss, more disintegrated 
than elsewhere. A series of caves was thus formed across the 
base of the peak, which eventually coalesced into a tunnel, the 
disintegration having been caused by the disruptive force of water 
while freezing.— -The second paper was “ On a Rare Plesiosaur 
from the Lias at Bridport.” After a brief account of the dis-
