W. Mathews on Glacier-motion. 99 
University of Wisconsin, November 18th, 1871. 
Art. XVL—On Canon Moseley’s views upon Glacier-motion ; by 
ILLIAM Maruews, President of the Alpine Club.* 
THE argument by which Canon Moseley attempts to prove 
that the descent of glaciers by their weight alone is a mechani- 
cal impossibility, as contained in his communication to the 
Royal Society, read January 7, 1869, may be stated in the fol- 
aes propositions :— 
_ 1. In every transverse section of a glacier every particle of 
ice is, at the same moment of time, moving over and alongside 
its neighbors, : 
_ 2. The absolute motion of any point in the surface of a glacier 
is proportional to its distance from the nearest side, and to its 
height from the bottom of the channel.
