No. 174 is of the 15th century, and contains the seventeen books: the first nine books are written by one transcriber, the last eight by another hand. The first nine books have been collated by Kramer. No. 173 contains the first ten books, and is of the middle of the 15th century. It is badly and incorrectly written. The last seven books, which would complete the codex, are, as Kramer conjectures from the paper and handwriting, in the Library of the Grand Duchy of Parma. From a note in Greek at the end of the 10th book, it appears to have been brought to Rome A. D. 1466. Books 1, 2, 4, and 5, collated by Kramer. No. 81 is tolerably well and correctly written. It contains the last eight books, and is of the end of the 15th century. It appears to be a copy of, or served as a copy to, the codex in the Laurentian Library, No. 19. Partially collated by Kramer. Medicean Codices, in the Laurentian Library, Florence: Codex 5 is elegantly and correctly written; it is of the beginning, probably, of the 15th century, and contains the first ten books. The 8th and 9th books are not entire; passages are curtailed, and much is omitted, to which the attention is not drawn, the lines being run on without spaces left to mark omissions. Errors of the first transcriber are corrected by a later hand, and noticed in the margin or between the lines. Collated by Bandini for Falconer, and almost the whole by Kramer. Codex 40 contains the first ten books; a copy, probably, of the former. It was written after the middle of the 15th century. Codex 15 is of the middle of the 15th century, and contains the last seven books. It is not in any way remarkable. Codex 19, written at the end of the 15th century. It contains the last eight books, and resembles No. 81 of the Vatican. Collated by Bandini for Falconer. Venetian Codices: No. 377 of the catalogue contains the first twelve books, and is written in the 15th century. Formerly the property of Cardinal Bessarion. No. 378 contains the seventeen books, of which the first twelve are apparently copies of the above, No. 377; the remaining five are transcribed from some other codex. This was, also, formerly the property of Cardinal Bessarion. No. 640 contains the last eight books. It was written, as appears from a note A. D. 1321, by different hands. A great part of the 14th book is wanting; eight blank pages are left for the completion of it; but this was not done by the transcriber to whom this portion was assigned. It is placed by Kramer in the first class of manuscripts, and was wholly collated by him. No. 379 is of the 15th century. It contains the Epitome of Gemistus Pletho of the first ten books, and the whole of the last seven books. It is the codex which served for the copy, No. 1398, in the Imperial Library at Paris. Formerly the property of Cardinal Bessarion.
