NOTE. 
Having no Colours to distinguish the Data for the Construction of the general 16 
Map, an account of it is here given in Writing. 
The Hughly & Jelenghee Rivers, together with that part of the Ganges w ch lies 
to y e Westw d . of Jelenghee is taken from a Map of Capt. Polier’s. 
The great Ganges from Jelenghee to its conflux with y e Megna, & likewise the 
Megna & Baramputrey from thence to Baganbarry, is laid down by exact Surveys. 
Dacca likewise is placed in its true Situation by means of a Survey from the mouth 
of the Issamuty to that Place. 
The Chunnunali & Comer Creeks are laid down from Surveys, but the Burrashee, 
Najapour, Beurygonga, Issamuty & Panghia Rivers are chiefly from the report of the 
Pilots. 
The Luckya River is from a Sketch taken lately, as likewise the Baramputrey 
from Baganbarry to Chilmary. 
The Ratitudes of the Southern Places are reckoned from an Observation of 
Eatitude taken at Euckypour in 1764. 1
