Mr. Stallybrass, the Siberian missionary, is at present here on his way to England, whither he is conducting his two sons, for the purpose of placing them in some establishment, where they may receive a better education than it is possible for him to give them in Siberia. I have seen him several times, and have heard him preach once at the Sarepta House. He is a clever, well-informed man, and in countenance and manner much like Mr. Swan--which similarity may perhaps be accounted for by their long residence under the same roof; for people who are in the habit of conversing together every day insensibly assume each other's habits, manner of speaking, and expression of countenance. Mr. Stallybrass's youngest son, a lad of fifteen, shows marks of talent which may make him useful in the missionary field for which he is intended. The most surprising instance of precocious talent that I have ever seen, or ever heard of, is exhibited in a young nobleman, who visits me every day. He is the eldest son of Count Fredro, Marshal of the Imperial Court, and though only fourteen years of age, speaks eight languages perfectly well, is a good Grecian and Latinist, is one of the best draftsmen in Russia, is well acquainted with physics, botany, geography, and history, and to crown all, has probably the most beautiful voice that ever mortal was gifted with. A admirable _Chrishna_ again by metempsychosis; the religion of the family, with whom I am very intimate, is the Romish. I now and then attend the service of the Armenian Church, for the purpose of perfecting myself in the language, and have formed many acquaintances amongst the congregation: there are several very clever and very learned Armenians in this place; one of them I will particularly mention, a little elderly gentleman of the name of Kudobashoff, who is the best Armenian scholar at present in existence. He is on the eve of publishing a work, calculated to be very interesting to us: an Armenian and Russian Dictionary, on which he has been occupied for the space of thirty-seven years, and which will be of the highest assistance to any future editor of the Armenian Scriptures; and be it known, that no place in Europe, with perhaps the exception of Venice, offers more advantages to the editing of the A.S. than St. Petersburg. I will now conclude, and repeat the assurance that I am ready to attempt anything which the Society may wish me to execute; and, at a moment's warning, will direct my course towards Canton, Pekin, or the court of the Grand Lama. With my best respects to Mr. Brandram, I have the honour to remain, Revd. and dear Sir, most truly yours, G. BORROW. To J. Tarn, Esq. (_Endorsed_: recd. May, 1835) ST. PETERSBURG, _April_ 28th [old style], 1835.
