At the time of my visit to the glacier hardly any of the last winter's 

 snow remained on its surface. The weather, which was tolerably fine 

 up to the 22nd May, after that day became very bad. Besides a good 

 deal of rain, about 3 inches of snow fell on the 23rd, and as much on 

 the 24th, and on the morning of the 25th, the clearer parts of the 

 upper end of the glacier were still covered with snow, though it had 

 melted on the moraines and open ground near the glacier. This bad 

 weather appears to have had considerable effect in retarding the motion 

 of the ice. 



I may as well here mention that the motion of the Mer de Glace, as 

 measured by Prof. Forbes, varied from 27 to 9 inches in 24 hours, in 

 different parts of the glacier, and at different times between the months 

 of June and September. The motion of the middle part of the glacier 

 of the Aar is also stated by M. Martins to be about 71 metres per 

 annum, which amounts to about 7i inches in 24 hours. 



The elevation of the foot of the glacier, where the Pindur leaves it, 

 determined by the comparison of corresponding Barometrical observa- 

 tions, made there and at Almora (5586 ft.], is 11,929 feet above the 

 sea. The elevation of the station where the Theodolite was fixed to 

 measure the motion of the glacier, was similarly found to be 12,946 

 feet ; and the elevation of the surface of the glacier near its lower end, 

 at a distance of about 6000 feet from the Theodolite station, being 

 about 12,140 feet ; the slope of the surface of the glacier is about 1\ 

 degrees.
