252 FRAGMENTS OF SCIENCE. 



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

 rock from a mountain-head, in the shoot of an ava- 

 lanche, in the plunge of a cataract, we often see more 

 impressive illustrations of the power of gravity than in 

 the motions of the stars. When the intellect has to 

 intervene, and calculation is necessary to the building 

 up of the conception, the expansion of the feelings 

 ceases to be proportional to the magnitude of the phe- 

 nomena. 



I will here record a few other measurements exe- 

 cuted on the Rosegg 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.

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.
