The death of Dr. Henry St. John Thackeray in June 1929 was a great grief to his many friends on both sides of the Atlantic. As a man and as a scholar he had rare and admirable qualities, and it is typical of him both as a man and as a scholar that when he undertook to make a translation of Josephus, of which four volumes have already appeared in the Loeb Classical Library, he first prepared a special lexicon for his own guidance, with no thought of printing it. The wise liberality of the Alexander Kohut Memorial Publication Fund, to which the work was introduced by Professor Cadbury, has now made possible the present publication, which has a form worthy of its contents. The first fascicule was seen through the press by its author, and arrangements have been made for the completion of the enterprise. It is of uncommon excellence.
