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.
