Sirinaker. The rivers of Panjab begin to abandon the Ptolemæan type. As Lahor
is correctly on the Ravi, the next river to the S.E., with Sultanpore, must be the
Bias, and the next, Coul fl., the Satlej, which has its sources in southern ramifica-
tions from Himalaya.

The great northern water-parting of the Indus and the Ganges is called Mont
de Caucase. North of it are the sources of Amu-darya, Tartarie, Tibet, and Turque-
stan. Tibet is shown as a little part of Tartarie. South of Mont de Caucase is a
network of ranges in all directions. One is called Dalanguer Mont, another Dow
Lager M., Dhaulagiri (?). Naugracut is not used as the name of a mountain, though
as a rule, on maps of the seventeenth century this denomination stands for nearly
the whole Himalaya. On Sanson's map it only signifies the province and the town
in Kangra, and is comparatively well placed.

The upper Ganges goes through a lake at Hardwar in Siba. Serenegar, known
from Andrade's journey, is placed below instead of above Hardwar. The Ganges
has still a nearly meridional course. The chief impression one gets from Sanson's
map is that it is founded on fresh and more reliable information in the country itself.

Another map of the same draughtsman has the title: Description de la Tar-
tarie, is engraved in Paris 1654, and published in Sanson's atlas: Cartes generales
de toutes les parties du monde, 1658 and 1677.¹ With a few exceptions this map
(Pl. XXX) shows all the characteristic features of those by Hoeius (Pl. XXVI) and Jans-
sonius (Pl. XXVIII). The Oechardes and Bautisus are there under somewhat changed
forms; on the latter Marco Polo's Sachiou is entered. The Caramoran or Hwangho
has dropped the branch which came from the great oblong lake, which, itself, has
disappeared. There is no sign yet of Koko-nor which will soon begin to wander
about in these regions as all the other lakes. The source of the Hwangho is situ-
ated at a short distance from the coast of the Glacial Ocean, just as before. The
Chinese have through centuries, though without sufficient proof, been supposed to
regard the Tarim as the upper course of the Hwangho. If this view has been
known to Ianssonius and other cartographers of the seventeenth century, one could
understand why they have placed the stations of Marco Polo on or near the upper
course of the Hwangho. The river (Pl. XXX), on which we read Calachitæ (Kara-
kitai?), and lower down Lop, should therefore be the Tarim. Cotam, Peim, and
Ciartiam (Cherchen) are placed south of the main river, as is indeed correct. As
the last fragments of Ptolemy's Oechardes and Bautisus, with Turfan and Camul, are
also, beyond doubt, the Tarim, we should be able to trace this river thrice on the
maps from the middle of the seventeenth century.

The classical Imaus, that is to say the northern half of its meridional part is still
there, near the source of the Hwangho. It seems to us strange to miss such geographical
