Ordinary Meeting, February 2 1st, 1860. 
J. C. Dyer, Esq., Vice-President, in the Chair. 
Mr. Hull, F.G.S., in continuation of his observations on 
the previous meeting, proceeded to remark that when roches 
moutonnees assumed the form of inclined planes or wedges, 
these forms not only indicated the former existence of a 
glacier, but also the direction from which the ice had moved, 
which, as a general rule, was opposite to that of the apex of 
the inclined plane. An example of this was exhibited in a 
sketch taken from the valley of Ambleside. 
Referring to the opinion of Professor Agassiz, that the High- 
land Districts had formerly been overspread by broad sheets 
(heppes) of ice, in a manner similar to that of Greenland at 
the present day, the Author proceeded to show that this 
opinion was borne out to a great extent by what he had 
observed in the Lake District. The phenomena in one 
locality appeared to show that the ice had been in such force 
and thickness, as to have been forced over a ridge or barrier 
five hundred feet above the bottom of the valley. He alluded 
to the flanks of Skelwith Fell, opposite the mouth of Great 
Langdale. Here the striae were found to ascend the flanks 
of this ridge to an elevation of about eight hundred feet above 
the sea, or five hundred feet above the bed of the valley. 
They were doubtless produced by the glacier which descended 
along the valley of Langdale ; and instead of turning to the 
left, and so entering the head of Windermere, the glacier was 
apparently forced over the opposite ridge. 
Mr. Hulk considered that this instance of glaciation, as 
also those at a considerable distance from the central chain of 
mountains, was attributable to the earliest of the three stages 
of the glacier period to which he alluded in his Paper ; and 
he proceeded to offer evidence in support of the existence of 
these three periods, which had been first indicated by Pro- 
fessor Ramsay, when treating of the old Welsh glaciers.
