1. On the movement of Glaciers.—A series of careful measure- 
ments has been made K. R. Kocw and Fr. Krocke on the 
Morteratsch glacier in feuiars Pibrvtln: nd. Their beet was a 
somewhat different one from that previous observers, as eae 
desired to determine whether in its eee downward course the 
movement was uniformly forward, or wheth er discontinnous cr at 
times backw ~ ide de ae were limited to the observa- 
tion of the movement of a point of the surface in a Vartionl plane 
parallel to the ihigth of the taal The method employed was 
as follows: Two scales, perpendicular to one another, were 
attached to the Auntie that one stood vertical and the other hore 
zontal, and their movements in their a ae directions were 
noted by means of a fixed telescope at a distance. 
The observations were carried on in the ones time from August 
Eine it was ikety to a free from ental variations. 
Selves were divided into half cen nee. but could be read by 
estimate to millimeters. As a control over the observations, and 
to prove that the movements were really ‘ious of the glacier and 
not of the rod itself, a second signal was planted in the ice near 
enough to the first to be included in the same field of view ; it
