by which material is deposited which binds the various pebbles or 
grains together. 
The Lecture was illustrated by means of the Oxy-hydrogen 
lantern, and specimens. : 
The next Meeting was held on Dec. 5th, when a paper on 
Glaciers was read by W. L. Mellersh. 
The Lecturer explained all the terms connected with Glaciers 
as, Snow line, Moraine and Crevasses, giving a short account of 
Avalanches and the motion of Glaciers which, like rivers, move 
faster in the centre than near the sides where they are retarded by 
the rocks over which they flow. A party of tourists were swept 
over a precipice by an Avalanche, and forty-one years later their 
bones came to the suiface of the Glacier ten thousand three 
hundred feet below where the accident had happened. 
The slides throughout were magnificent and very freely used, 
the principal Glaciers and noted mountains from which these ice- 
rivers start being shewn. 
Mr. Hichens made a few remarks about the Great Ice Age, 
when Glaciers existed over the greater part of Europe. But 
at present the Glaciers are slowly retreating. A block of granite is 
to be seen near Filey which was carried across England from the 
Penine Range and deposited where it now stands.
