3. "Atlas Russien: contenant une Carte Générale et dix-neuf Cartes particulieres de tout l'Empire de Russie et des Pays limitrophes construites conformément aux règles de la Geographie et aux dernières Observations. Par l'Académie Impériale des Sciences de St. Petersbourg. St. Petersbourg, 1745." This was the first atlas published in Russia in the map department established by order of Peter the Great in the Academy of Sciences of St. Petersburg. It includes a general map of the Russian Empire and nineteen maps of provinces. {207} 4. "Carte de la Sibérie et des Pays voisins. Pour servir a Histoire générale des Voyages par le S. Bellin, Ing. de la Marine," two parts, undated, but to which E. Dufosse, of Paris, assigns the date of 1749. The atlas for this work was originally published by Abbe Prevost at Paris, 1747, et seq., the charts being engraved by Bellin. This chart appears on casual inspection to be more accurate than either that of d'Anville or of de l'Isle, or of the Russian atlas. 5. The very interesting and valuable map of J. N. de l'Isle, Paris, 1752 (without, however, the accompanying memoir). I do not think the original map has ever fallen under the notice of Professor Dall, although a garbled reproduction of it is mentioned in his review as follows: "A chart which deserves notice, though almost wholly fictitious, being chiefly devoted to the spurious discoveries of the alleged Admiral de Fonte, was issued by J. N. de l'Isle with the concurrence of M. P. Bauche or at his suggestion. It appeared at Paris in 1752, and was copied for Jeffery's second edition of voyages from Asia to America in 1764. I do not know if this copy appeared in the first edition, but presume it did." As the original of de l'Isle's chart (1752) is here exhibited to-night, it is evident that Jeffery was careless, and that the map, which I infer Dall has never seen, is really more valuable than is set forth in his address; otherwise so critical an observer as Dall would not have said: "I suspect this (referring to d'Anville's map of 1753, with Bering island thereon) is the first publication of a cartographic kind on which Bering island is laid down, as the map of the Imperial Academy of Sciences, embodying the geographical results of Bering's voyage to the coast of America, was not engraved until a year later, while de l'Isle's of 1752 does not contain them." You will see that this is an error, for the "I(sle) de Beering" is plainly inscribed on the map. (This map has been reproduced by photolithography and forms the accompanying plate 21.) [Illustration: PLATE 21. CARTE GÉNÉRALE DES DÉCOUVERTES de l'Amiral de Fonte.] Dall further describes the copy of this map in the following terms:
