A transcript, 1750, by 'William Owen o Gonwy yn Sir Gaernarfon ...' of 'cywyddau' and 'englynion' by Lewis Morris, John Roger, Hugh Hughes, Dafydd ap Gwilym, Wiliam Cynwal, Sion Tudur, William Sion, Owen Gruffydd, Michael Prichard, Hwmffre Dafydd ab Ifan, Wiliam ap Huw Llŷn, Huw Morus, Robert Humphreys ('Robin Rhagad'), Sion Rhydderch, Sion Dafydd Lâs, Ellis Rowland, Wiliam Phylip, Dafydd Manuel, John Vaughan (Caergai) and 'Thomas Llwyd Ifangc'.

Welsh poetry in the same hand as Mostyn MS 160 and Peniarth MS 114. The poets cited include Guto'r Glyn, Sion Phylip, Dafydd Nanmor and Wiliam Llŷn.

Canwyll y Cymry, carols and 'dyrïau', being compositions of the Reverend Rice Prichard, M.A. ('Yr Hen Ficer') (1579?-1644) (pp. 7-146), vicar of Llandovery, and others in the hand of William Salisbury, Bachymbyd. The manuscript was completed on 20th April 1637 (see pp. 148b, 327). The Reverend Prichard's works include a considerable number which seem never to have been published. Some of the poets whose works appear include Rhys Cain, Sion Tudur, Edmwnd Prys and Llywarch Hen. On p. 328 there is a note on the hot summer and early harvest of the year 1638, the harvest of 1637, and high winds in October 1638.

A manuscript containing poetry in praise of Gruffydd Dwnn, the bulk of it being in the autograph of Gruffydd Dwnn, though pp. 12 (Rhisiart Fynglwyd), 19 ('Syr John Teg'), 22 (Sion Brwynog), 41, 69, 108, 120 (Syr Owain ap Gwilym), 73, 74 (Morgan Elfael), 132c (Huw Llŷn), and 145 (unattributed, possibly autograph) are autograph works by the respective authors. Many of the poems are dated. Pp. 147-156 are in the holograph of Huw Llŷn (see notes on pp. 149, 153). P. 17 is inscribed 'ai kant pan oeddid yn kwplav y plas [nyr ystrad merthyr] o. k. 1533'. An inscription on p. 49 notes Syr Owain ap Gwilym as being 'ap Ieuan o dal y llynn' and, in relation to the poem, 'ai gwnaeth i ryffydd dwnn o hiraeth am rvffydd ag o eisse i weled ac ai danovones ynysgrifenedig i ryffyth donn' (see Peniarth MS 70, which evidently once belonged to the Gruffydd Dwnn Collection). P. 77 is inscribed probably in the hand of Gruffydd Dwnn (relating to the date 1533) 'pan oedd rys [the eldest son of Gruffydd Dwnn] yn 11 mlwydd oed. I mayr kywydd hwnn yn ysgrifenedig mywn llyfr arall i ryffydd Dwnn kyfaillt y llyfr hwnn'. On p. 83 the name of 'syr John teg' has been crossed out and that of 'Gyttvn Owein' [Gutun Owain] substituted, though Gutun Owain was dead long before the poem's date of 1526; the text, however, appears to be in the autograph of Gruffydd Dwnn. The last line of the poem beginning at p. 87 may not belong to the first as pp. 89-90 are missing. P. 104 is inscribed, apparently in the hand of Huw Llŷn in relation to the author of the work, Morus Dwyfech, 'ai kant pann oedd o. k. 1560 ac ynn hir llyn i gwnnaeth ef y ddau englynn hynn'. P. 126 is inscribed in the hand of Gruffydd Dwnn 'I mayr varnad honn yn ysgrifenedig yn y llyfr lle may englynyon yr eryr o law y gwr ai gwnaeth yr hwn lyfr a wnaeth gryffydd dwnn iddo i hyn yn gyntaf oll ond vn llyfr arall'. P. 144 is inscribed in the hand of Gruffydd Dwnn 'gyttvn owein ai kant i ryffydd dwnn' (although, according to the date of the poem, Gruffydd Dwnn was an infant at the time of its writing). P. 147 is inscribed (in relation to Wiliam Cynwal, the author of the englynion) 'a Gant y chwech englyn hynn yni ynnwedic lythr at ruffudd dwnn 1566' (only the fifth and sixth englyn of this series remain).
This is one of the manuscripts mentioned in Mostyn MS 184. Gwenogvryn (J. Gwenogvryn Evans, Report on Manuscripts in the Welsh Language, vol. II, part II (London, 1903), p. 503) debates whether the englynion addressed to 'Gr: Dwnn o Gydweli' on at pp. 132-132b are in the hand of Owain Gwynedd.
