which was one of the hardest and best paying labours I accomplished in Turkology, and which advanced me to the title of specialist in Turkish languages. From the _Turkish Grammar_ by Davids, and an article of Joubert's in the _Journal Asiatique_, I had heard of the existence of a mysterious Uiguric manuscript, and when Lord Strangford, moreover, drew my attention to it, and advised me to try and decipher it, I burned with ambition, and did not rest until I had secured the loan of this precious manuscript from the Imperial Library at Vienna. The faint, uncertain characters, the value of which I had to guess in many cases, the curious wording, and the peculiarly original contents of the text, exercised an overpowering charm over me. For more than a year I gazed daily for hours at the sybillic signs, until at last I succeeded bit by bit in reading and understanding the manuscript. My joy was boundless. I immediately decided to publish the deciphered portion, and when, after much trouble and expense, for the type had first to be made, I saw the imposing quarto before my eyes, I really believed I had accomplished an important work. I was strengthened in this idea by the extremely appreciative comments of my colleagues, and yet it was but a delusion, for my knowledge of the dialects in the northern and north-easterly frontier districts of the Turkish languages, was not sufficient to enable me to understand the entire manuscript, and to accomplish the deciphering of the entire document. My better qualified and more thoroughly versed successor, Dr. W. Radloff, was able to show better results at once, and the only satisfaction that remains to me from this laborious task is the fact that to me belongs the right of priority; and that Dr. Radloff, following in my footsteps, attained after thirty years a higher standpoint and wider view, is due in a large measure to the fact that in course of time he managed to secure a copy of the _Kudatku Biliks_ written in Arabic characters, and consequently more legible. And so my _Uiguric Linguistic Monuments_, in spite of many faults and defects, ranks among the showpieces of my scientific-literary activity. In any case I had proved that without being a schooled philologist one can be a pioneer in this line. Following up this only partially successful experiment, I continued for some time my researches in the field of Turkology. I wrote an-- 5. _Etymological Dictionary of the Turkish Language_,
