A transcript, made by John Jones, Gellilyfdy, 1605-1606, of 'Pum Llyfr Kerddwriaeth', attributed to Dafydd Ddu Athro, and of 'Ffugrau a'u Rhannau' by Wiliam Salesbury.

A fragment of a manuscript written by David Ellis, Criccieth, containing a 'cywydd' which he addressed to Rhys Jones o'r Blaenau; 'carolau' on 'Charity Meistres', 'Mawl Merch', 'Gwel'r Adeilad', and 'King's ffarwel'; a 'cywydd' to 'Dafydd Siôn'; a fragment of a bardic grammar; 'marwnadau' - Robert Davies, Llannerch, Lewis Morris (Evan Evans, 'Ieuan Brydydd Hir'), 'rhyw delyniwr' (Simwnt Fychan), and Siôn Rhydderch (incomplete).

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.
