The inscribed tablet discovered in the grave-creek mound, Virginia, and which was noticed by Mr. Schoolcraft in the first volume of the Transactions of the American Ethnological Society, continues to excite much interest. Mr. Jomard of the French Institute, read a second paper on that subject last year, before the Academy of Inscriptions and Belles-lettres at Paris, a copy of which he has transmitted to the Society.[4] He distinctly shows, that the letters of this curious inscription are identically the same as those of the Libyan on the monument of Thugga,[5] and of the Tuarycks used at this day. It is worthy of remark, that Mr. Hodgson in his "Notes on Africa,"[6] arrived at the same conclusion, without the knowledge that Mr. Jomard, some years previously, had asserted the Libyan character of this inscription, in a first note on the subject.[7] Such a coincidence gives force to the views adopted by both these gentlemen. The results to which the French savant has arrived, in his enquiry into this engraved stone or tablet, possess much interest, as it is the only relic yet discovered in North America, of an inscription bearing alphabetic characters,[8] which have been satisfactorily identified as such. This Numidian inscription, which title we may now apply to the engraved tablet in question, will be again alluded to, when we come to speak of the philological discoveries in Northern Africa, and of the Libyan alphabet. In conclusion Mr. Jomard observes, that at a remote period the Libyan language was spoken by various tribes in Northern Africa, and that it was a language written with characters, such as we now find on the Thugga edifice and other monuments; that it is still written with the same characters, particularly in the vicinity of Fezzan and in the deserts traversed by the Tuarycks, although this method of writing has been to so great an extent supplanted by Arabic letters that we must consider the Berber language, the language of Syouah, Sokna, Audjelah, and Gherma, as representing the remains of the ancient Libyan language in use in the most remote period; and finally, that in the interior of America, on a monument of which the age is unknown, but anterior to the settlement by Europeans, we find an engraved stone, bearing signs perfectly resembling the characters traced by the modern Tuarycks and by their ancestors, upon the rocks of Libya. Mr. Jomard's pamphlet contains an engraved table, in which are given, in parallel columns, the characters on the American tablet, the Tuaryck alphabet, the Thugga characters, and their value in Hebrew and Arabic.
