D i 1
This is a large volume, bound in calf, tooled (cover measuring ca. 21 X 14); inscribed on spine: "Irish MSS. Facsimiles. No. 65, Press I" (A former no. xx appears beneath the present no.) Stowe and Ashburnham Collections. Main ms. was originally blank, and was used as a portfolio to house sections of original mss. lithographed by Astle as specimens of handwriting for his Origin and Progress of Writing (1784). The borrowed sections of mss., apparently eighteen in number (to judge by Astle's Plate xxii), were retained by Astle and never returned to their parent mss. ! Later further sections of manuscript were added, and finally the blank pages were used by Dr. Charles O'Conor for a first draft of a projected edition of the works of St. Columbanus (see below).
For convenience of reference the various sections of ms. are described below under the article nos. used by O'Conor in describing this ms., Bibl. MSS. Stowensis, Press no. I, 65, and in the ms. itself. O'Conor catalogues only the nós. I-VIII (his VII is our VIII ), although IX (a) at least apparently formed part of the ms. when he drew up his catalogue. The nos. X-XXI and the entries in the main book are almost entirely O'Conor's own work, and were added after the Stowe catalogue had been printed. It is important to notice that the two vellum folios (I Additional infra) now loose in the ms. and preceding I, were not in the ms. in O'Conor's time, nor were they there when Purton catalogued the contents (see Acad. Obs. 163). They have probably got transferred here from another R.I.A. ms. Purton's No. I is now missing from the volume (it consisted of a vellum leaf bearing a Latin copy of the Gospels and a second vellum fragment of an Ossianic tale, and was possibly once part of IX (a) which had got misplaced). The present cataloguer believes that this must be the material catalogued separately as 1215 supra. Purton's No. II is our I (he ignores our (and O'Conor's) II altogether); his (and O'Conor's) V (one folio vellum, 5 leaves paper) is now missing, possibly transferred back to its parent ms., E iv. 1 (no. 751 supra); Purton's (and O'Conor's) VII is our VIII; his VIII a our IX (c); his VIII b apparently the medical seetion of our IX(a) or has got transferred; his VIII c is our IX (b). It is to be regretted that these transfers (if they are transfers and not losses) were made silently. They should not have been made without being noted in D. i. 1. The present cataloguer has now noted in pencil on the blank pp. of D. i. 1 the location of all sections whieh lie loose between the pages, and are therefore easily liable to bé displaced.

Another section preserves a fragment of an unidentified Fenian romance, in which "fían Éireann," Oscor, and Aongus mac in Dagda play a part. Still another fragment, so firmly thonged in that the reverse of folio cannot be seen without undoing the thongs, is a poem beg. Eisdsi riumsi, a Mhuire mór. A specimen of Latin blackletter is also among these fragments.
