An effort will be made to obtain a copy of the original logbook,[7] but for the present we are obliged to be content with what of authenticity remains to the data which have been translated or paraphrased by Bergh, Lauridsen and Olson, necessarily submitting to more or less modification in the process. [Footnote 7: Simultaneously with the proofs of this paper the work of Bergh has been communicated to me through the liberality of the University of Upsala, Sweden. The results of a critical examination of it will form the subject of a later paper as the present publication cannot be delayed.] The most authentic and important document for the history of this voyage is naturally the official report handed in by Bering himself and printed in the Journal of the Military Topographical Depot of the Russian Army, volume x, pp. 67-79, St. Petersburg, 1847. This journal is a quarto and the report is printed _verbatim et literatim_ if one may judge by the archaic and mispelled words with which it is adorned. It comprises Bering's report including his instructions, a table of geographical positions, and a painfully detailed table of routes and distances by which his position in Kamchatka was computed. This report has never been translated in full and unmodified, the original is thought to have been lost. The present publication is not referred to by Lauridsen and was apparently unknown to him. I have therefore thought it worth while to prepare an English version of the report and geographical table which are incorporated in this paper. The result shows that the previous versions of the report which have appeared were more or less mutilated or colored by the editors printing them, probably with the view of making the report of more popular interest to their readers but with injurious results to its historic value for reference. We now come to the latest contributions to the subject. If it were not for the deficiencies in them, which seem to me serious, this paper would not have been prepared, but it seemed to be a pity that the sources of information in regard to Bering, accessible to those who do not read Russian should not be both more impartial and more accurate.
