60 Tableau of High Asia. [No. 1, 
be adduced the fact, that we found the isothermal lines for the year 
and the summer, which coincided with the snow-line on the Indian 
side, decidedly warmer than those on a level with the Tibetan snow- 
line. The fact, moreover, of the Karakorim—though on an average 
three degrees farther north —having the snow-line so excessively high 
on both its slopes, offers another instance of the influence of limited 
precipitation. 
In the Kiinliin, the meteorological conditions also become apparent 
in the different limits of the snow-line on either side; but here the 
effect is the reverse of that perceived in the Himalaya, the greater 
precipitation on the ‘‘ northern” slopes (towards the plains of Turkis- 
tan) lowering the snow-line on that side to a considerable extent. 
Although, in the Himalaya at large, the snow-limit of the Tibetan 
side does not descend so low as that of the Indian, yet the influence 
of exposition at once becomes apparent in the ordinary sense, corre- 
sponding to these latitudes, if we examine the slopes of a crest or 
mountain, of which, by the nature of its position, both slopes belong 
either to the Indian side of the ridge in general, or to the Tibetan 
side. The many and vehement disputes upon the much-discussed 
subject of snow-limits have chiefly arisen from the entire neglect of 
this modification.* 
The values we obtain for the height of the snow-line on the three 
mountain chains of High Asva are :
