A S no aftronomical obfervations have been taken in 

 the voyages related in this colle<5lion, the longitude 

 and latitude afcribed to the new-difcovered iflands in the 

 journals and upon the charts cannot be abfolutely de- 

 pended upon. Indeed the reader will perceive, that the 

 pofition •' of the Fox Iflands upon the general map of 

 Ruffia is materially different from that afllgned to them 

 upon the chart of Krenitzin and LevafliefF. Without 

 endeavouring to clear up any difficulties which may 

 arife from this uncertainty, I thought it would be moft 

 fatisfadtory to have the beft charts engraved : the reader 

 ■will then be able to compare them with each other, and 

 with the feveral journals. Which reprefentation of the 

 new-difcovered iflands deferves the preferance, will pro- 

 bably be afcertained upon the return of captain Gierke 

 from his prefent expedition.
