results, which were not unknown to him, as he quotes him in connection with other
questions. In spite of this controversy Anquetil du Perron expresses the highest
admiration for Rennell's work.

On Rennell's map we recognise the same bends of the rivers as on D'AN-
VILLE's Lama map, and we find Chaparang and Choumorty on the same place.
The outlines of the lakes and the mountains are not quite the same, although it is
not said why the changes have been made. No names have been given to the
lakes and the distance between them is much greater than on d'Anville's map,
which is by far the better of the two.

A meridional range separates the basin of the »Ganges» from that of the
Brahmaputra, and the northern part of this range is called Mount Kentaisse.

The uppermost part of the Brahmaputra is also a little changed from d'An-
ville's map, and by some curious luck, really a little improved. Thus we may
identify, with some good will, the southern branch with the Kubi-tsangpo, the middle
one with the Chema-yundung and the northern one with the Maryum-chu, although
the resemblance with the reality is only vague. On Rennell's map the Maryum-
chu goes through a lake which may be supposed to be the Gunchu-tso, although
this lake is drawn much better on the Lama map, where it has got its real name
and is correctly placed on the western, and not on the eastern side of the water-
parting.

The Lamas have the correct name Tamtchou Mts at the source of the south-
ern (Kubi) branch of the Tsangpo, whereas Rennell writes the legend: »Heads of
the Ganges and Burrampooter (or Sanpoo) Rivers», just south and S.E. of the
Manasarovar. He has also spoilt the small rivers entering the lake, which are
admirably drawn on the Lama map. But the most important characteristics are
these: a channel between the two lakes and a river, supposed to be the Ganges,
leaving the Rakas-tal, and so far the results of the Lamas' work are saved on Ren-
nell's map.

Only the mountains at the southern side of the Tsangpo are put in. The
road, which he believed was travelled by GEORGI, although this Father had never
been in Tibet, is marked from station to station. Chamnamrim of the Lama map
has become Chanmanning, which is not an improvement on the real Shang Nam-
ling. Most other names are as easy to recognise as on the Lama map. The greatest
merit of the map, so far as Tibet is concerned, is, however, that Rennell under-
stood that the Brahmaputra must be the lower course of the Tsangpo. From this
point of view the Tibetan part of his map is a historical document of eminent value
and importance.

I reproduce here on Pl. I the region round the lakes, as it is represented
on a later edition of Rennell's map.¹ The source of the Satlej is placed a little
