In the Greek Library, each seat contained 50 volumes; in the Inner Library, 31 volumes; in the _Bibliotheca pontificia_, 21 volumes. In the next place I will give the results of the examination of a catalogue[394] of the Library, which M. Fabre, with much probability, assigns to the year 1512[395]. It begins as follows with the Latin Library: Ad sinistra' Pontificis bibliothecam introeuntibus In primo scanno supra [27] " " infra [27] Finis primi scanni sub et supra [54] The nine seats (_banchi_) of the left side of the Latin Library are gone through in the same way as the first, with the result that each is shewn to have two shelves. The total number of books is 457, or 27 more than in 1481. On the opposite, or right-hand side of the Library, the first two seats have three shelves, and are described as follows: In primo scanno supra [22] " " infra [27] " eodem scanno inferius siue sub infra [26] Finis primi scanni sub et subter [75]
