 to be fulfilled before they could begin; the labour and Ikill 



to 



The whole of Hudfon's Bay I took from a chart, compiled by Mr. Marley, from 

 all the mod authentic maps he could procure of thofe parts with which I was favoured 

 by Samuel Wegg, Efq; F. R. S. and Governor of that Company, who alio po- 

 litely furnifhed me with Mr. Hearne's Journals, and the map of his route to the 

 Coppermine River, which is faithfully inferted on the chart, together with the fur- 

 vey of Chefterfield Inlet made by Captain Chriftopher and Mr. Mofes Norton, in 

 1762 ; and the difcoveries from York Fort to Cumberland, and Hudfon Houfes 

 (this iaft is the moft Weftern fettlement belonging to the Company), extending to 

 Lake Winipeg, from the drafts of Mr. Philip Turnor, made in 1778 and 1779, cor- 

 rected by aftronomical obfervations. And from this lake, the difpofition of the other 

 lakes to the Southward of it, and which communicate with it, is formed, and laid 

 down from a map conftrufted by Mr. Spurrel, in the Company's fervice. The 

 Albany and Moofe rivers to Gloucefter Houfe, and to Lake Abbitibbe and Superior, 

 are alfo drawn from a map of Mr. Tumor's, adjufted by obfervations for the lon- 

 gitudes. 



The Weft coaft of Greenland, as chiefly laid down from the obfervations made by 

 Lieut. R. Pickerfgill in the Lion brig in 1776, which determine the line of the 

 coaft only, as the immenfe quantities of ice choak up every bay and inlet on this 

 coaft, which formerly were, in the fummer feafon, quite free and open. 



From the mouth of the Miffifippi River, including its fource, and the other rivers 

 branching from it ; all the coaft of New Leon to Cape Rozo, and the Weftern coaft 

 of America, from Cape Corrienties to the Great Bay of Tecoantepec, is taken from 

 Monfieur D'Anville. 



The Gulf of California I have laid down from a German publication in 1773, 

 put into my hands by Sir Jofeph Banks, Bart. P. R. S. ; and the Weftern fide of it 

 is brought together from aSpanlfli MS. chart with which A. Dalrymple, Efq; F. R.S. 

 obliged me. 



The coaft of Brazil from Sera to Cape Frio, is copied from a fmall chart of that 

 part by Mr. Dalrymple. 



For the Southern part of Africa, from the Cape of Good Hope to Point Natal, I 

 have taken the authority of the chart of Major J. Rennels, F. R. S. fliewing the ex- 

 tent of the bank of Lagullus. 



For the exiftence of the fmall iflands, fhoals, and banks to the Eaftward of Ma- 

 dagafcar, together with the Archipelago of the Maldive and Laccidive Iflands ; for 

 the coafts of Mallacca, part of Cambodia, and the Ifland Sumatra, I have ufed the 

 lateft authority of Monfieur D'Apres de Mannevillette's publications in the 

 Neptune Oriental.
