Aet. IV . — Account of a Map of the Route between Tartary 
and Amarapura, by an Ambassador from the Court of Ava 
to the Emperor of China. By Francis Hamilton, M. D. 
' F. B. S. & F. A. S. Lond. & Edin. Communicated by the 
Author. 
A FIE map, of which the accompanying is a reduced copy, 
see Plate I., was given to Captain Symes, the British Resident 
at Ava, by the Zabua of Bhanmo or Panmo, who had been 
on an embassy to the court of China, and who repeatedly sent 
one of his officers to me, in order to explain such matters 
in the map as occasioned difficulty. This officer accompa- 
nied his master on the embassy, where both had acquired a 
knowledge of the world, and a politeness, that distinguish- 
ed them much from other Mranma (Burma) chiefs ; and the 
officer at least was acquainted with the Chinese language, ha- 
• ving been born on the frontier of the empire, and educated in a 
: town where many Chinese have settled. The map is one of the 
rudest, which I procured ; but is important as tending to settle, 
by high and perfectly informed authority, many most interest- 
ing points respecting the rivers which enter the farther penin- 
sula of India from Thibet and China, and thus enabling us to 
decide with more confidence on the relative situations of differ- 
ent places in other maps, which contain a greater detail, and are 
laid down with more skill. It is for this reason that I have gi- 
ven this as a preliminary to maps, in other respects of more 
merit. 
The embassy from the king of Ava received audience of the 
Chinese monarch at what they called the capital of Tarsek, that 
is of Tartary, meaning probably the Emperods hunting-seat at 
Gehol. From thence they returned over a chain of mountains.
