"_This day_ (24th August 1718) the king being in Paris, having authentic proofs of the profound erudition of the S. Guillaume de l'Isle, _of the Royal Academy of Sciences_, in the great number of geographical works which he has executed for his Majesty's use, and which have been received with general approbation by the public, his Majesty, by the advice," &c. &c., "wishing to attach him more particularly to his Majesty's service by a title of honour, which may procure him at the same time the means of continuing works of such usefulness, has declared, and declares, wishes, and enjoins, that the said S. de l'Isle be _henceforward_ ['DORESNAVANT'] his first geographer," &c. &c. This appointment was signed by the king, and countersigned by the Secretary of State. It was distinctly sworn by M. Teulet and M. Jacobs, than whom there could not have been higher authorities on such a subject, that they had carefully examined the map in question--and that, till the 24th August 1718, there never was a map of De l'Isle thrown off having on its face the title of "Premier Géographe du Roi;" but that, _after_ that date, this designation was invariably added to his name;--and though the period of printing was later than 1718, it was necessary to retain the original date of the map, 1703, _in order to secure the copyright_; because the privilege of printing it, as recited on the map, extended to only twenty years from the time of the map being originally published. Thus was clearly and most satisfactorily explained the erasure of the word "Géographe" after the name of Guillaume de l'Isle, and the contemporaneous interpolation of the new title of dignity--_Premier géographe du Roy_--between the next line and the one following. All the three witnesses (MM. Teulet, Jacobs, and Mr Lizars) swore, and gave conclusive reasons for doing so, that the same copperplate was used in making the engravings--that De l'Isle was in the habit of retouching his plates, and making alterations in them from time to time; and great numbers of his plates were produced, showing that, in the maps dated anterior to 1718, the words "Premier Géographe du Roy" were _interpolated_; and in the one before the court, the interpolated line was much "fresher" than the rest of the inscription. In those subsequent to 1718 there was no such interpolation, the words being always regular with the other part of the title." In addition to this, it was proved, that the word "Géographe" had been mechanically effaced from the copper; for, on carefully examining the under side of the copper, there were "evident traces of hammering, which had been done to fill up the spaces where the words had been effaced." Nothing could be more lucid and decisive than the evidence given by the eminent M. Teulet on these points; the result being a downright demonstration, as far as the nature of the case admitted of demonstration, that the copy of the map in question
