THE PRESIDENT (PROFESSOR BABINGTON) in the Chair. 
The following communication was made to the Society: 
On some Fresh Observations of the Water-holes on the 
Gorner Glacier. By Mr Trotter. 
The attention of the Society was called last year to certain 
water-holes on the Gorner Glacier associated with hummocks of 
ice on their southern edges (first observed by the speaker in 
1863). (See Proceedings, Oct. 19, 1874.) 
The holes as they appeared at the latter part of the season 
were oval, with their longer axes pretty exactly east and west, 
the larger axis about double of the smaller, the depth on an 
average nearly double the longer axis, the longer axis varying 
from about 1 to 6 or 8 long. The holes as usual had gravel 
at the bottom, and had usually a hummock of ice at the 
southern side, the height of which was often nearly equal 
to the longer axis in the smaller holes, somewhat less in pro- 
portion in the larger ones. 
The larger axis was sometimes parallel, or nearly so, to the 
veined structure, sometimes cut it at a greater or less angle, so 
that the holes were clearly independent of the veined structure, 
and seemed to be clearly a meridian phenomenon. 
The speaker had the opportunity of observing these holes 
last summer, about the end of June, when they were much less 
perfectly formed. The surface of the glacier was covered in 
places with new snow, and in others the winter’s snow was 
imperfectly melted. Some of the holes, however, were fairly
