The case or shrine of the _Book of Mulling_ appears to have been originally plain, except for some small pieces of crystal and lapis lazuli inserted on one side. In 1402, however, a very large crystal set in fine niello work was inserted in the same side. In 1891, thinking I saw trace of a letter under this crystal, I raised it, and thereby revealed a brass plate hitherto concealed by dust, and bearing the inscription: “++Artturus | ver domin | us & lageniae | rinsdabe | tilia & baroni | anno & dni | millio | quadrin | gentesi | mo sedo |++.” This Arthur was Arthur or Art MacMurrough Kavanagh, who opposed Richard II. This inscription, no doubt, has reference to the insertion of the crystal and the niello work, not to the original construction of the case. This MS. also contains a _Missa Infirmorum_ (published by Bishop Forbes with that in the _Book of Dimma_). Another beautiful Latin MS. of Irish origin is the _Psalter of Ricemarch_, so called because it was formerly in the possession of that prelate (Bishop of St. David’s, d. 1099), who has written in it some Latin verses. It is perhaps not much older than his time. The book was the property of Bishop Bedell, whose autograph it bears, and was lent by him to Archbishop Ussher, and to this circumstance it owes its preservation, Bedell’s library having been destroyed in the troubles of the time. The last of these Latin Biblical MSS. which I shall mention is not Irish, but is somewhat of a curiosity. It is a single leaf of the _Codex Palatinus_, a fifth-century MS. of the old Latin version of the Gospels written in silver letters on purple vellum. The rest of the MS. (so far as it has been preserved) is in the Imperial Library at Vienna, which acquired it at some unknown period between 1800 and 1829. Our leaf was purchased by Dr. Todd in 1843. It is not improbable that the MS. was abstracted from some monastic library during the Napoleonic wars, and that this leaf, becoming separated from the rest, came into the hands of an Irish soldier. This dispersion of a MS. is less unusual than might be supposed. The _Book of Leinster_, to be presently mentioned, furnishes a notable example.[130] I recently received from a correspondent two leaves of a Syriac MS., which, by the help of Wright’s catalogue, Dr. Gwynn identified as two of the missing leaves of a MS. in the British Museum, the MS. having been imperfect when purchased for that Library. The _Book of Hymns_ (11th century) deserves mention both for the beauty of its initial letters and for the interest of its contents. Some of the hymns are Latin, some Gælic; the greater part of both has been published by the Irish Archæological Society, with learned notes by Dr. Todd, and with reproductions of the initial letters. The remainder of the Gælic hymns has been published by Dr. Whitley Stokes in his _Goidilica_.
