Dzungarian Post, Chonimailachu, (sheep-bleating,) are
scarcely raised 850, or at the most 1170, feet above the level
of the sea. Pansner’s older barometric measurements —
(which, however, were not published until after my expedi-
tion), are confirmed by mine. Both refute the hypothesis ©
of Chappe, relative to the supposed high elevation of the banks
of the Irtysh, in Southern Siberia; an hypothesis based on
estimations of river declivities. Even further to the Kast,
Lake Baikal is only 222 toises, or 1420 English feet, above
the level of the sea.
In order to connect the idea of the relation of
the terms lowlands and highlands and of the various
gradations in the height of elevated plains or undulating
grounds, with actual examples ascertained by measurement,
I have subjoined a table, forming an ascending scale of such
districts in different parts of the Globe. What I have
said above respecting the mean height of those Asiatic
pains, which I have termed lowlands, may be compared


with the following numbers :-—
Toises. English feet.
