Ixxxii INTRODUCTION. 



to be exerted in finifliing many of them, rendered this a 

 tedious operation ; paper fit for printing them upon was to 

 be procured from abroad ; and after all thefe various and 

 unavoidable difliculties were furmounted, much time was 

 neceilarily required for executing a numerous impreffion of 

 the- long lift of plates, with fo much care as might do juftice 

 both to Mr. Webber, and to his feveral engravers. When 

 all thefe circumftances are taken into confideration, we truft 

 that we fhall hear no more of the delay j and only be grate- 



thc Ganges, and Barampooter or Sanpoo Rivers, are inferted from the work of the 

 ingenious Author of the map of Hindooftan, publifhed in 1782. 



The China fea is laid down from the chart publifhed by Mr. Dalrymple ; but the 

 longitudes of Pula Sapata, Pulo Condore, Pulo Timoan, Straits of Banca and 

 Sunda, and the parts we faw are as fettled by us, together with the Eaft coafl: of 

 Niplion, the principal of the Japenefe Iflands. 



The Jefo and Kurile iflands, the Eaft coaft of Ada and Kamtfchatka, as well as 

 the fea of Okotfk, and the iflands lying between Kamtfchatka and America that were 

 not feen in the voyage, are taken from a Ruffian MS. chart, got by us at the Ifland 

 of Oonalafhka. 



The Northern countries from Cape Kanin, near the White Sea, as far Eaft as 

 the River Lena, I have given from the Great Ruffian Map, publifiied at Peterfburg 

 in 1776, including the Euxine, Cafpian, and Aral Seas, as alfo the principal lakes 

 to the Eaftward ; the intent of which is to fliew the fource of the large rivers that 

 empty themfclvts into the diff'erent oceans and feas. 



Every other part of the chart not mentioned in this account, is as originally placed 

 by Captain Cook. 



The whole has been correfied from the lateff aftronomical obfervations, feleiSted' 

 from the Tables compiled by Mr. William Wales, F. R. S. and mathematical mafter 

 of Chrift's Hofpital, for the Nautical Almanacs : From thofe in the Mariner's Guide 

 by the Rev. Dr. Mafkelyne, F. R. S. and Aftronomer Royal, publifhed in 1763 ; 

 From the Connoiffance des Temps for 1780 and 1781 ; From Profefibr Mayer's 

 Geographical Table ; From the Voy-ages of MelTrs. d'Eveux de Fleurien, Verdun, 

 rie Borda, and Chabet, oic, ; From the Table lately publifhed by Mr. Dalrymple 

 for the ufe of the Eaft India fhips ; From the Philofophical Tranfaftions of the Royal 

 Society J and from ifie Obfervations of our late Navigators.
