I. ENUMERATION OF THE MATERIALS OF OBSERVATIONS.
Comparison and combination of the heights obtained. — Abbreviations used for the observers, books, and maps:
A. India and Himalaya in general; B. India; C. Himalaya and Tibet.
COMPARISON AND COMBINATION OF THE HEIGHTS OBTAINED.
It being our aim to present a general tableau, as complete and correct as possible,
of the hypsometric conditions of India and High Asia, we have combined with our own
observations1 a carefully detailed compilation of all the existing materials which we were
able to collect, though it has proved a much more laborious task than we had anti-
cipated, on account of the materials being scattered throughout a great number of
books, pamphlets, and maps, and even manuscripts, and provincial publications of India.
We have, besides, embodied the results of previous observers, not only for such places
and localities which we were ourselves unable to visit, but also for those actually
determined by ourselves. In the latter case former determinations, when based on
detailed measurements, offered at the same time a valuable control for our own obser-
vations, and could, moreover, be included in the means. The instances, however, where
means could be taken were much less numerous than we had expected; they were,
indeed, comparatively speaking, very rare, since for a critical examination it is of im-
portance to know the original observer, and the nature of the method upon which
his result is based, and these two points it was often very difficult, and sometimes im-
possible, to elucidate. We were also prevented from taking means at a vast number
of places, because the spot of observation, or the "locality", as we propose to call it,

Vol. I., p. 8; the trigonometric determinations in Nos. 7 and 8.
