THROUGH ASIA 
absurd to think of using in such a place. But by the 
route we followed on April i8th, and again on August 6th 
and 1 6th, there were, as far as I could make out with my 
field -glass, no insurmountable physical obstacles in the 
way ; and any climber possessed of sufficiently strong lungs 
ought to be able to work his way up to the northern 
summit. And although that is not the higher of the 
twin peaks, it is connected with its loftier brother by a 
slightly depressed col. Between and below the two ex- 
tends the ndvd ox firn of the great Yam-bulak glacier; but 
how far it admits of being traversed is another question. 
In all probability it is cut up with crevasses and covered 
with deep snow, so that it would require some days to 
effect a passage across. The barriers behind which the 
eternally Happy of the legendary city of Janaidar have 
entrenched themselves are indeed insurmountable ! 
Man’s physical functions are influenced in no small 
degree by the rarefaction of the air ; and in order to 
ascertain in what way this acted, I registered at different 
altitudes the temperature of the body and the pulse in 
myself (29 years old), in Islam Bai, a native of Osh in 
Fergana (43 years old), and in the Kipchak Kirghiz, Yehim 
Bai from Shugnan (40 years old).

altitudes.
