tain will allow of being transferred, with sufficient accuracy for 
our object, to the other, if we deduct about 3500 feet from the 
Himalaya heights in comparison with the Alps—which is about 
the difference of the snow limits on the south slope of both ranges. 
And what state of things do we find in the Indian Alps? “It 
is remarkable,” says Rirrer, “ that there never has been any re- 
port of a single glacier formation throughout Himalaya. The 
sublime phenomenon of glaciers, which appear to have attained 
their most perfect development in the European Alp-formation, 
according to any observations hitherto made, never occurs in the 
Himalayan Alp-region.” Thus, at first sight we are cut off fromany 
comparison here and instead of immeasurable fields of ice, many 
thousand feet thick, which we expected to see, we only meet with 
snow on the peaks and caps in no greater, rather in smaller quan- 
tities than on the Alps at their present heights. But a closer 
view, points out another result, which may be pronounced almost 
decisive of our question. With the elevation of the ground, all 
the isothermal lines mount up rapidly in height. On the south 
slope of the Himalaya, we meet with the extreme limit of culti- 
vation at 9400 feet; in the deep indented vallies of the interior, 
it mounts up to 10,700 feet ; on the plateau land, to 12,800 feet; 
and on the interior table land of Thibet, which can be best com- 
pared with the upraised lowland of the molasse region, the same 
appears at 14,000 feet, whence it goes no higher. This eleva- 
tion would correspond to perhaps 10,000 feet, in our latitude, or 
to the heights of Diableret and Fitlis. Hence, a rise of ground, 
even twice as great as that required by H. v. C., never appears t0 
produce the formation of such extraordinary glaciers as must be 
assumed in order for the glacier to have formed the ice-piles of the 
Rhone-valley, which at the Jura, must have mounted over the 
valley-bottom about 2000 feet, and which must have extended 
below to Soleure. We should arrive at still more striking co} 
clusion, were we to apply the glaciers theory to the Scandinaviay 
blocks, and yet it is scarcely allowable to explain such similar @p- 
pearances as occur in North Germany and Switzerland, by tW° 
altogether different theories. What if in the hill country, at the 
foot of the glacierless Himalaya, the phenomenon of erratic block 
should reappear? Several accounts seems to establish the fact 
beyond a doubt.
