¹ Shortly after the appearance of the note which I contributed to the April number of the Classical Review (pp. 162–4), and in which further proof was given of the identity of the codex now at Holkham with No. 498 of the old Cluni catalogue, I had the gratification of hearing from M. Henri Omont, of the Bibliothèque Nationale, that the same ex libris mark (de conventu Clun.) had turned up—this time in quite indisputable shape—in the Paris MS nouv. acq. lat. 638, ‘ Antiquiores consuetudines Cluniacensis monasterii, collectore sancto Udalrico, discipulo sancti Hugonis, magni abbatis Cluniacensis ’ (saec. xi). Curiously enough this manuscript is not included in the old catalogue (compiled between 1158 and 1161),—possibly because it may have been a manual in general use. As the two book-marks seem to be in the same hand, we may make the inference that the whole collection was catalogued in this way at the same time, and further identifications may now be expected.
