^{Page 207 note 1} I am indebted to Mr C. J. E. Ball (who initiated this investigation) and to Dr N. R. Ker both of whom have read earlier drafts of this paper and have contributed valuable criticisms and suggestions. I am also indebted to Professor B. Bischoff for help on various points and to him and to Mons. F. Hauchecorne for references. However, I am alone responsible for the views expressed. I owe the opportunity to examine the manuscript to Dr P. J. F. Obbema, the Keeper of Western Manuscripts, who accorded me special facilities and many other kindnesses. He drew my attention to the stimulating article by Professor Gerritsen (discussed below), thus enabling me to read it with the manuscript in front of me, and also discussed various readings with me. I am indebted to the Librarian at Leiden for permission to reproduce the photograph of the manuscript.

^{Page 207 note 3} This experiment was undertaken by Mr A. Austin from a photograph available in Oxford. The effect of such prints is to heighten the contrasts, thus emphasizing very faint traces obscured beneath only a light film of reagent.

^{Page 215 note 4} Orléans 342 contains both the earlier and the later neums. The main hand of this manuscript is dated s. x-xi by Professor Bischoff, but the manuscript does not contain an ex libris inscription. The Calligraphy of the later neums is illustrated from an eleventh-century addition to a Fleury manuscript now in the Vatican Library by Bannister, Monumenti Vaticani, pi. I7(b), no. 132. Compare especially the formation of the clivis and the quilismata in this plate with those alongside the text of the riddle.
