the present ends of the glaciers of Ibi Gamin, of Joharna, and of 

 Photi, and are elevated some hundred feet above the present level 

 of the ice. This greater extension of the glaciers has evidently- 

 belonged to the historical period, since the ancient moraines repose 

 constantly upon all the older tertiary and diluvial strata, and if we 

 are not mistaken a diminution in the extent of some of these glaciers 

 is still going on at present. 



We wish especially to remark, that this greater extension of the 

 Himalayan glaciers, at some former period, is a phenomenon very 

 different from that which gave rise to what has been called in 

 Europe the "glacier theory," by which an attempt was made to 

 explain, on the hypothesis of a former enormous extension of the 

 Alpine glaciers, the existence of the great erratic deposits all around 

 the Alps, where the erratic blocks are in situations very different 

 from the ancient moraines in the Himalayan glaciers.* 



"We are not as yet prepared to give an opinion about the physical 

 causes (changes of climate, and general subsidence or elevation,) 

 which may have produced this difference in the extension of the 

 glaciers.

 the Upper Indus Valley, and of the ascent to the Ibi Gamin JPeak 

 by Adolphe Schlagtntweit and Robert Schlagtntweit. 



We left Milum on the 6th of July, with Mani, the Putwarri of 

 Johar, and a good number of Jubboos and people, since we wanted 

 to send all our baggage by the upper road to Niti. After crossing 

 the Uta Dhura Pass, we went up, with a few people only, to the 

 Janti Pass, (18,650 E. F.,) where we staid for three days, which
