The mean altitude of the ten lakes is 4692 m. Omitting the three unreliable lakes, Shudun-tso, Kyaring-tso and Dangra-yum-tso, the mean altitude becomes only I o m. higher, or 4702 m.
The mean altitude of the known passes in the range north of these lakes, we have already found to be 5174 m. The depression of the ten lakes is therefore 482 m. below the mean pass altitude to the north. But as the passes signify the lowest points of a range, the relative mean crest altitude of the latter will of course be much greater above the depression. On the other hand, the lakes are also the lowest points of the depression, and therefore the two values are commensurable.
The following is a list of the known first-class water-parting passes of the Transhimalaya. They are 32, of which only I I are known as to their altitudes ; of the existence of 19 passes I was informed by the natives without having an opportunity to visit them. I only know their situation approximately. The names within brackets indicate the discoverers ; in some cases the same pass has been used by two or three explorers.

I The altitude of Shudun-tso is certainly too high, and that of Kyaring-tso too low. The altitude of Dangra-yum-tso is unreliable, as I derived it from calculation and not from direct observation. My 4646 m., however, agrees well with Nain Sing's 4657 m. at a very short distance from the northern shore.
