Schlagintweit, Hermann von; Schlagintweit, Adolf; Schlagintweit, Robert von: Results of a scientific mission to India and High Asia: undertaken between the years MDCCCLIV and MDCCCLVIII, by order of the court of directors of the hon. East India Company (Band 2): General hypsometry of India, the Himalaya, and Western Tibet, with sections across the chains of the Karakorúm and Kuenlúen: comprising, in addition to messrs. de Schlagintweit's determinations, the data collected from books, maps, and private communications (Leipzig, 1862)

PREFACE.

The compilation and computation of the existing hypsometrical
materials for India and High Asia being now terminated, we are in
a position to indicate by a few figures the data upon which our
knowledge in this branch of science is based, up to the present month
of November, 1861. This enumeration may be considered at the same
time as a general outline of the labours hitherto completed in hypso-
metry by our predecessors and ourselves.

The present volume contains, in all, the heights of 3,495 points, of
which 1,615 belong to India, and 1,880 to High Asia. The area over
which they are distributed extends from the southern parts of Ceylon
to the environs of Kashgar in Turkistan (from 6° to 39° Lat. N.), and
from the eastern boundaries of Assam to Sindh (from 97° to 70V2°
Long. E. Gr.).

Of the 3,495 points mentioned above, there are 1,113 for which
we had no other determination hut our own; of these new data 378
belong to India and 735 to High Asia. Besides these, we had occasion
to add 144 points, some of which were determined anew; others are
points for which differential values only had been formerly given,
and which we had now the opportunity of connecting with the level
of the sea.
