3. Nouvelle carte des dècouvertes faites par des vaisseaux Russiens aux cotés inconnus de l'Amerique septentrionale avec les pais adjacens, dressés sur les memoires authentiques de ceux qui ont assisté à ces dècouvertes, et sur d'autres connoissances; dont on rend raison dans un memoire separé: à St. Petersburg, à l'Academie Imperiale des Sciences, 1754. 1758.
This map was published under the inspection of Mr. Muller, and is still prefixed to his account of the Russian discoveries[142]. The part which exhibits the new discovered isles and the coast of America, was chiefly taken from the chart of Beering's expedition. Accordingly that continent is represented as advancing, between 50 and 60 degrees of latitude, to within a small distance of Kamtchatka. Nor could there be any reason to suspect, that such experienced sailors as Beering and Tschirikoff had mistaken a chain of islands for promontories belonging to America, until subsequent navigators had actually sailed through that very part, which was supposed to be a continent.
4. A second chart published by the Academy, but not under the inspection of Mr. Muller, bears the same title as the former.
Nouvelle carte des dècouvertes faites par des vaisseaux Russiens aut côtés inconnus de l'Amerique, &c. 1773.
It is for the most part a copy of a manuscript chart known in Russia by the name of the chart of the Promyshlenics, or merchant adventurers, and which was sketched from the mere reports of persons who had sailed to the New Discovered Islands. As to the size and position of the New Discovered Islands, this chart of the Academy is extremely erroneous: it is however free from the above-mentioned mistake, which runs through all the former charts, namely, the representing of the coast of America, between 50 and 60 degrees of latitude, as contiguous to Kamtchatka. It likewise removes that part of the same continent lying in latitude 66, from 210° longitude to 224°, and in its stead lays down a large island, which stretches between latitude 64° and 71° 30´, from 207° longitude to 218°, to within a small distance of both continents. But whether this latter alteration be equally justifiable or not, is a question, the decision of which must be left to future navigators[143].
5. Carte du nouvel Archipel du Nord decouvert parles Russes dans la mer de Kamtchatka et d'Anadir.
This chart is prefixed to Mr. Stæhlin's account of the New Northern Archipelago. In the English translation it is called, A Map of the New Northern Archipelago, discovered by the Russians in the seas of Kamtchatka and Anadyr. It differs from the last mentioned chart only in the size and position of a few of the islands, and in the addition of five or six new ones, and is equally incorrect. The New Discovered Islands are classed in this chart into three groups, which are called the Isles of Anadyr[144], the Olutorian[145] Isles, and the Aleütian Isles. The two last mentioned charts are alluded to, p. 26 of this work.
