“This mention has none the less escaped, according to all appearances, Professor de Goeje, of Leyden, who nevertheless was acquainted with this passage of Pott (since he mentions it, p. 16, so as to induce the belief that the learned professor of Halle was the first to establish a connexion between the Zott or Djatt and the Tsigans), and who quotes in several places my long articles in the _Revue Critique_ on ‘Les derniers travaux relatifs aux Bohémiens dans l’Europe Orientale’ (of which the _tirage à part_ forms an octavo volume of 80 pages, 1872), but who says not a word of my work of 1849. This is an omission such as the most conscientious savants sometimes make; and I do not intend to address a reproach to the learned professor of Leyden, whose work must besides have all the superiority belonging to a deep study made twenty-five years later by a most competent Orientalist. But since the question of priority upon this subject has been raised in your paper, you will, I think, perceive, in perusing what I wrote in 1849, which I send you with this letter, that I have a right not to be completely forgotten, especially when it concerns an interesting point in the history of the Gipsies upon which I have hitherto published only some fragmentary works, but to the study of which I have devoted so many years. “My letter is already long: allow me, nevertheless, to add yet a few more words. Although I have in my possession the work of Professor de Goeje (the author has had the kindness to send it to me), I cannot say that I am acquainted with it, because I cannot read Dutch, and have not yet found an opportunity of having it translated, which I doubly regret under the present circumstances. I think, however, that I may say that the point treated by the professor of Leyden, and twenty-five years ago by myself, although it be already sufficiently complex, is only one side of the very much more complicated question of the origin of the Gipsies, considered in all its bearings. I hope to be able to show that the historical documents of Eastern Europe, of Western Asia, and of Egypt itself furnish very important data, hitherto very insufficiently considered, upon the question. I think I have also the means of giving an explanation of the word _tsigan_, and of the other names approaching to it, more certain and more interesting than those proposed by Professor de Goeje and Mr. Burton.
