SIXTEENTH LETTER ON GLACIERS. 



[1850. 



TABLE shewing the mean daily motion in inches of the Glaciers of Chamouni, 

 deduced from Balmaf s Observations, and continued from [page 128]. 



In my former Letters I have taken occasion to mention 

 experiments and observations which have occurred from time 

 to time of a nature to confirm the fundamental hypothesis of 

 the quasi fluidity of the ice of glaciers on the great scale, and 

 I cannot doubt that these incidental remarks have tended to 

 diminish the natural incredulity with which that theory was at 

 first received in some quarters. I have now to cite a fact of 



* Mean of Geneva and Great St. Bernard. 



f [There is much reason to think that Balmat, in entering or transcribing these 

 observations, has put those on the Glacier du Bois in place of those on the Glacier 

 des Bossons, and vice versa. It would farther appear that the renewed station on 

 the Glacier des Bois, after the interruption of the observations, did not exactly 

 coincide with the old one, as it shows a smaller annual fluctuation of velocity. See 

 also note to page 139.]
