Bishop Moore, of Norwich, afterwards of Ely, presented his library, more than a century ago, to the University of Cambridge. Among his large collection of books was a vellum MS. of 86 folios, about six inches long by three broad. It is said that this MS. is as old as the ninth century. The principal part of it is written in Latin, and contains John’s Gospel and portions of the other three Gospels, the Apostles’ Creed, and part of an Office for the visitation of the sick. It belonged to an establishment of the Culdee Church, and is an interesting relic of the Celtic learning and culture of the time, particularly of the ecclesiastics of that Church, who, while cultivating their native Gaelic, could also read and write Latin. To the Gaelic scholar the chief interest lies in the Celtic portion of the MS.—the Gaelic entries made on the margin and on other spaces in the volume. The MS. was published some years ago by the Spalding Club, under the excellent editorship of the late Dr John Stuart, who has given us the Gaelic entries as well as the original in a scholarly and careful fashion. A Gaelic paragraph on the founding of the old monastery of Deer has attracted much attention, on account of its reference to Columba, and because it shows the intimate connection that existed between the parent establishment at Iona and branch establishments in distant parts of Scotland. The _Legend of Deer_ is as follows:— Columcille acus drostán mac cósgreg adálta tangator áhí marroalseg día doíb gonic abbordobóir acus béde cruthnec robomormáer buchan aragínn acus essé rothídnaig dóib ingathráig sáin insaere gobraíth ómormaer acus óthóséc. tangator asááthle sen incathraig ele acus doráten ricolumcille sí iarfallán dórath dé acus dorodloeg arinmormáer .i. bédé gondas tabrád dó acus níthárat acus rogab mac dó galár iarnéré na gleréc acus robomaréb act mádbec iarsén dochuíd inmormáer dattác na glerec góndendaes ernacde les inmac gondisád slánte dó acus dórat inedbairt doíb nácloic intiprat goníce chlóic pette mic garnáit doronsat innernacde acus tanic slante dó; Iarsén dorat collumcille dódrostán inchadráig sén acus rosbenact acus foracaib imbrether gebe tisad ris nabab blienec buadacc tangatar deara drostán arscartháin fri collumcille rolaboir collumcille bedeár áním óhúnn ímácc.
