Thus according to the hydrometrical data Kara-koschun would be 102.o meters lower than Jangi-köl. But this is no doubt too much. For by means of 136 meteorological observations made by Dr. Hedin in the Tarim delta at Kara-koschun and its environs and of simultaneous observations made at the permanent stations Jangiköl and Tscharklik, the probable altitude of Kara-koschun above sea-level appears to be 816 meters. Now the altitude of Jangi-köl being 881 meters, and supposing Kum-tschapghan to be i meter above Kara-koschun, the difference of altitude between Jangi-köl and Kum-tschapghan ought to be 64 meters. For this reason
I have reduced all differences of altitude in the above table in the rate Iô4 and
thus found the corrected numbers given in the last column, which I consider as the most probable.
Now the length of the river was measured between all stations from Jangiköl to Kum-tschapghan and a curve drawn as explained above, with the lengths as abscissa and the altitudes above Kum-tschapghan as ordinates. and from this construction the following table was obtained.
