FEAGMENTS OF SCIENCE. 



partial ability to conceive it. In the falling of a rock 

 from a mountain-bead, in tbe sboot of an avalanche, in 

 tbe plunge of a cataract, we often see more impressive 

 illustrations of tbe power of gravity than in the motions 

 of the stars. When the intellect has to intervene, and 

 calculation is necessary to tbe building up of the con- 

 ception, the expansion of the feelings ceases to be 

 proportional to the magnitude of the phenomena. 



I will here record a few other measurements exe- 

 cuted on the Eosegg glacier : the line was staked out 

 across the trunk formed by the junction of the Rosegg 

 proper with the Tschierva glacier, a short distance 

 below the rocky promontory called Agaliogs. 



Rosegg Glacier. 



This is an extremely slowly moving glacier; the 

 maximum motion hardly amounts to seven inches a day. 

 Crevasses prevented us from continuing the line quite 

 across the glacier.
