As no astronomical observations have been taken in the voyages related in this collection, the longitude and latitude ascribed to the new-discovered islands in the journals and upon the charts cannot be absolutely depended upon. Indeed the reader will perceive, that the position[4] of the Fox Islands upon the general map of Russia is materially different from that assigned to them upon the chart of Krenitzin and Levasheff. Without endeavouring to clear up any difficulties which may arise from this uncertainty, I thought it would be most satisfactory to have the best charts engraved: the reader will then be able to compare them with each other, and with the several journals. Which representation of the new-discovered islands deserves the preferance, will probably be ascertained upon the return of captain Clerke from his present expedition.
