PROFESSOR CAYLEY in the Chair. 
On some Ice-hummocks in the Gorner Glacier. 
~ By Mr Trorter. . 
The speaker described some remarkable water-holes asso- 
ciated with hummocks of ice on parts of the Gorner Glacier 
which he had observed in 1863 and in 1874. The water-holes 
were oval in shape with their longer ones parallel and pointing 
east and west, the hummocks were on the south side of the 
water-holes, The direction was independent of that of the 
veined structure, and the whole was obviously a meridian 
phenomenon, but several points as to the origin of the hum- 
mocks and the shape of the water-holes were very obscure. 
An examination of them earlier in the season would pro- 
bably throw some light on their origin.
