Mr. Panton' [i.e. Panton MS.40 now NLW MS 2008]; 168-9, five stanzas of a hymn tune attributed to Elis Wynn; 169, a transcript of two 'englynion' attributed to Dr. [John] Davies; 171, a list of the commotes and hundreds of Glamorgan copied from '68.

In a note on the aforementioned 'title-page' (p. 199) Edward Williams claims to have transcribed this collection in 1799 from a manuscript in the possession of Siams Thomas of Maerdy Newydd, co. Glamorgan. Preceding and following the actual text of the collection are transcripts of a prefatory letter dated 1685 (pp. 201-06) and of the concluding note already referred to (p. 390) both of which are attributed to the Glamorgan scribe and copyist Thomas ab Iefan of Tre Bryn as compiler of the manuscript from which Edward Williams was allegedly copying (see TLLM, t. 172; IM, tt. 291-4). Pp. 391-477 contain a transcript of a collection, in alphabetical order, of over three thousand Welsh proverbs attributed to Cattwg Ddoeth ('Llyma Ddiarhebion Cattwg Ddoeth . . . sef yw hwnn Ail Lyfr y Gwyddfardd Cyvarwydd'). This collection, according to the aforementioned note at the end of the preceding section (p. 390) attributed to Thomas ab Iefan, had been compiled by the said Thomas from various sources and formed a continuation of the previous section. Edward Williams's claim with regard to the Siams Thomas volume is probably intended to apply to the contents of pp. 391-477 as well. The contents of pp. 199-390 have been published in The Myvyrian Archaiology of Wales . . ., vol. III (London, 1807), pp. 1-99.

An imperfect volume, the contents consisting of transcripts, in a hand possibly of the first half of the seventeenth century, of Welsh poems being mainly strict-metre poems in the form of 'cywyddau'. These are numbered and, if the manuscript when complete contained the whole sequence, the folios at the beginning containing poems 1-18 and most of poem 19 are now wanting. Many mid-volume and possibly some end folios are also missing. Poems by the following poets are included - Iolo Goch (2), Siôn y Cent (13 ), Siôn Tydyr, Lewys Morgannwg (5), Davydd Epynt, Ieuanap Rydderch ap Ieuan Llwyd (3), Davydd Ddu Hiraddug, Davydd ap Edmwnt (3), Ieuan Brydydd Hir, Davydd Nannmor, Gytto'r Glynn (2), Lewis i Glynn (3), Gryffydd Llwyd ap Davydd ap Enion, Hyw Llvn, Syrr Philip Emlyn, Lle'n ap Howel ap Ieuan ap Gronw (4), William Egwad, Gwilim Tew, Iorwerth Vynglwyd, Howel Swrdwal, Howel Davydd ap Ieuan ap Res (4), Siôn Brwynog, Ievan Tew Brydydd, Thomas Lle'n, Hyw Davi, Rys Goch 'o Vachgarn', Robert Laia, Ieuan Tew Brydydd Ievanc, Risiart ap Rys, Thomas Derllysg (2), Wiliam Cynvol, Siôn Phylib, Edwart ap Rys, Morys ap Howel, Gwyrfyl verch Howel Vychan, and Meredydd ap Rys.

An imperfect manuscript consisting of thirty folios of uniform size and two smaller leaves, with the two halves of ? the lower cover of an early nineteenth century periodical or part publication, which at one time seems to have served as a protective covering, bound in at the beginning. A considerable part of the original manuscript appears to have been lost as the volume was described by the Reverend John Williams ('Ab Ithel'), circa 1856, as containing 'about 100 pages' (see L. James: Hopkiniaid Morganwg . . . (Bangor, 1909), p. 91). The former protective cover bears the inscription 'Llyfr Llanfihangel Iorwerth. Cywyddau amrafaelion. Siôn Cent hyd Dafydd Hopcin o'r Coetty. Englynion Eiry Mynydd, &c.', in the hand of Edward Williams ('Iolo Morganwg'), and the contents consist of transcripts of Welsh verse mainly in strict metre. Dafydd Hopkin of Coety, co. Glamorgan is sometimes named as the copyist (see L. James: op. cit., p. 91; TLLM, tt. 229, 267; and IMCY, t. 139). The poems include 'cywyddau' and 'englynion' by Thomas Prys, Ieuan Tew Brydydd, Dafydd Hopkin (1734), Ieuan Brechfa, Lewis Morganwg, Iorwerth Fynglwyd, Dafydd ap Gwilym, Rys Dynfwal (sic), Rhys ab Morys, ?Mredydd ap Rees, Swrdwal Hen, Huw Dafydd Probert, Siôn Tudur, Owain Gwynedd, Gwilim ap Ieuan Hen, Dafydd ap Edmwnt, Daio Lliwiell, Ieuan Tew Brydydd Ifangc, Huw Lewis, Gruffydd ab Ifan ab Llewelyn Fychan, Wiliam Cynwal, Morus ab Hywel ab Tudur, Siôn Cent, Hywel ab D'd ab Ieuan ab Rhys, Llywelyn Goch, Gruffydd Dafydd Fychan, Ieuan ab Hywel Swrdwal, Bleddyn Fardd, and Dafydd Llwyd Fach, a series of pseudo- gnomic poems with each stanza commencing with the words 'Eira mynydd' some of which are attributed to Llywarch Hen and Mabclaf ab Llywarch, and poems attributed to Taliesin and Aneurin. There are marginal notes by Edward Williams and his son Taliesin Williams.
