ASTRONOMICAL DETERMINATIONS OF LATITUDES AND LONGITUDES.
Tibet and Turkistan, whilst the principal chain, that of the Karakorum, had either been
left out or considered as of secondary importance only,1 and we, therefore, could not be
surprised to find, from our own observations, and, farther to the north, from the combi-
nation of various itineraries, that the longitude is on an average 2° too much to the
east; the latitude, however, differs very little, being on an average only 9' too high.

Academy of Science at Paris, October, 1857.
