CONCLUDING GENERAL REMARKS AND RESULTS.
271
Puling), a satisfactory coincidence with former latitudes; but the longitudes we found
to be more to the west than had hitherto been supposed. The difference, however, does
not on the average exceed 10' in the eastern parts of Grnari Khorsum, and 8' in
the western.
3. The latitudes of SpUi and Ladak, in Western Tibet, are generally given too
high; but the difference is very small; those of Bdlti differ much more from our own
determinations, being generally laid down considerably too low, with an error
exceeding 10' even at the principal places, as Skardo and Shigar. In addition to
these corrections, a number of places, not yet contained in any map, have been fixed
from direct observations by Adolphe along his various routes in 1856.
The differences of longitude are still greater. The northern part of Western
Tibet, throughout its vast extent, must, according to our observations, be placed
22' to 25' more to the west; for the south-western margin, the error of the longitude
is smaller, on an average 18' to 12'.
This result at first surprised us; but the G. T. S., recently extended as far as
Srinagger, has also found the longitude of the Vuler lake to be 22' • 5 more to the
west than was till now generally laid down on maps.
The progress of the Gr. T. S. also enables us to profit by our general and detailed
comparison of chronometers at Srinagger, to connect all our chronometric longitudes
of Western Tibet direct with those of the Gr. T. S. in Kashmir.
4. The positions to the north of Tibet, in the Kuenhten and in TurMstdn,
have been hitherto laid down according to various data carefully collected and made
known by Klaproth. They are chiefly based on Chinese authorities, and on some
old observations made by missionaries in the 17th century.
Some few of the latitudes had been determined by altitudes of Polaris; the longitudes
were referred to Peking. But the accuracy of these positions had always been con-
sidered doubtful by many geographers. We found, that on the maps even the second-
ary range of the Kuenluen had hitherto been mistaken for the watershed between
