PLANTJE SCHLAGINTWEITIANA, 117 
For a height of 16,500 feet in the different parts of the mountain 
system, the following annual mean temperatures are resulting from the 
data obtained by Messrs. de Schlagintweit :—*

In reference to thse EE iia ide iinei Mr. Her- 
mann de Schlagintweit-Sakünlünski has communicated to me the 
following data; these are taken from the large work entitled ‘ Results 
of a Scientific Mission to India and High Asia’ (Leipsic, Brockhaus ; 
London, Trübner), of which four volumes in quarto and forty-six 
plates of the atlas of panoramas, views, and maps, are now pub- 
lished. The following abstract, appearing for the first time in an 
English journal,t may be useful in reference to many a question of 
botanical geography. 
“High Asia is the mountainous region extending from Bhutan in 
the east to Kabul in the west, and, in the northerly direction, from the 
tarais along the southern foot of the Himalaya on the Indian side, to 
the northern foot of the Künlün, where a wide depression separates 
the High Asiatie mountainous system from those following in Central 
Asia, and further to the north. In geographical degrees, the limits 
of this territory are the following :— Latitude, north, from 28 8° to 37°; 
longitude, east, Greenwich, from 72° to 95°. Fully to estimate such 
an extent of territory, it may be sufficient to keep in mind the Alps ; 
from Avignon to Vienna, for instance, there is a difference of 12? of 
lojitade ; the breadth of the Alps, in latitude, does not even amount 
to a difference of 4°; the surface covered by the Alps is only one- 
tenth of the basis of High Asia."
