A manuscript, in the hand of Evan Evans (Ieuan Fardd), containing 'Cerddwriaeth Simwnt Fychan' (ff. 1-43 verso, first sequence) and the 'Rhetoreg' of William Salesbury, which was originally a translation of a Latin treatise on rhetoric (ff. 1-47, second sequence). There are copious references to the source materials for both parts, the names mentioned including John Jones, Gellilyfdy, William Maurice and Roger Morris (ff. 1 (first sequence), 46 verso (second sequence)). A note by Ieuan Fardd states that he transcribed these works in 1776 (f. 46 verso). For Simwnt Fychan's 'Cerddwriaeth' see also Peniarth MS 159 and Jesus College MS 9.
A composite volume, mainly in the autograph of Evan Evans (Ieuan Fardd), copied from manuscripts of Lewis Morris and others 'ynghylch y flwyddyn 1765' (p. i), including 'Englynion y Beddau' (pp. 1-15) and 'Englynion y Clywed' (pp. 15-28); 'Gildas Nennius' (pp. 49-60). The second part (ff. 1-35) contains 'Hanes Taliessin' (pp. 61-69); genealogies taken from a manuscript of Robert Vaughan, Hengwrt (pp. 80-89); extracts from Dares Phrygius, Brut y Brenhinedd and Brut y Tywysogion (pp. 97-101); Bonedd y Saint (pp. 109-115); 'Hanes yr ymrysson rhwng Edmund Prys a W. Cynwal' (pp. 117-123); notes and extracts; etc. A letter, 7 December 1758, from Lewis Morris, Penbryn, to Evan Evans, Llanllechid, is tipped into the volume (pp. 135-138).
A manuscript containing Welsh laws (pp. 1-96) and the 'Elucidations' (pp. 97-535), written in the hand of John Jones, Gellilyfdy prior to 25 September 1619 (see pp. 67, 535). Where the text is imperfect Moses Williams has written its contents in the margins. The text of pp. 1-96 of this manuscript corresponds with that of Peniarth MS 29, pp. 1-51, while the remainder may be a copy of Peniarth MS 278. The original of pp. 97-535 was either imperfect or frequently illegible as dots indicating lacunae are frequent. Much of the matter of this second part is the same as the 'Elucidations' in Ancient Laws and Institutes of Wales, Vol. ii, Book XIV. The text ends abruptly at the beginning of the sixth line on p. 535.
A manuscript containing Brut y Brenhinedd, after 'Ifan Llwyd ap Dafydd o Nantmynach o fewn Sir Feirioydd [sic], Esquier'. Pp. 1-9 are in the hand of the Reverend Moses Williams.
