A sixteenth-century manuscript containing a medical treatise in Welsh, recipes, charms, and an astrological fragment; a treatise on uroscopy in English; poetry, including a cywydd by Ieuan Brydydd Hir (hynaf); 'Llythyr Aresdotlys [...] o gadwedigaeth korff dyn ac gavas ynte yn hemyl yr havl [...]' (pp. 228-237); and a prologue to a work which is called 'Compod' ('o herwydd I vod ef yn comprehendio [...] kompod Manuwel') (pp. 197-200).
The manuscript is written in several hands of the early to late sixteenth century, possibly including that of its original owner Bened ap Rhys (Bened Feddyg) of Llanelidan, Dyffryn Clwyd, as well as Tudur ab Elise (see p. 150).

A volume of Welsh poetry mostly in the hand of Humphrey Davies (Wmffre Dafis), [vicar of Darowen], contining copies of cywyddau and awdlau by well-known and less known poets from the early fourteenth century to the early seventeenth century (pp. 25-492). Some poets are well represented, especially Ieuan Tew, Sion Keri and Huw Arwystl.
Twelve folios at the beginning (pp. 1-24), as well as six (formerly loose) folios at the end (pp. 493-504) are in the hand of Evan Lloyd of Blayn glyn, a former owner of the volume. These include a copy of a version of the dialogue between Hadrian and Epictetus, beginning: 'llyma ymddiddanion Rhwng adram [sic] emerodr Rhufein ag Epig y ddav wr calla yn y bvd', which differs greatly from the text found in Llyfr Yr Angkr and the Hengwrt MSS (pp. 3-7). Two other leaves (now bound in at the end of the volume), one bearing a Welsh poem in free metre (pp. 505-506) and the other an assessment of Derwen parish, [Denbighshire] (pp. 507-508), do not seem to belong to this volume.

A composite volume, the first portion of which (pp. 1-78, old foliation 1-38), written in the early eighteenth century, contains selections from Flores poetarum, triads, englynion, the divisions of Wales (pp. 29-33), cywyddau, poems in free metre, and an incomplete table of the contents of the latter portion of the volume (pp. 57-59). The second part of the volume (pp. 79-406, old foliation 1-245 with gaps) has been neatly written in two or more hands, one of the seventeenth century and the others of the early eighteenth century. It contains Welsh poems in strict and free metres from the fifteenth to the eighteenth centuries, many of them either of Anglesey interest or written by Anglesey poets, particularly Lewis Môn, Sion Brwynog and John Griffith of Llanddyfnan.
Among miscellaneous items are copies of the Articles of Agreement between the Parliamentary Commissioners and the inhabitants of Anglesey, 1648 (pp. 295-296); Sir Edward Trevor's riddle (p. 312); and a short bardic grammar (pp. 358-362).

A cursory examination of the items included in the manuscript suggests that about ten of the poems are not recorded in other manuscripts. The volume is written in several hands of the late sixteenth century including those of Simwnt Fychan (ff. 73-75) and Wiliam Cynwal (ff. 79-81), two of the bardic pupils of Gruffudd Hiraethog, and also the hand of Rhys Cain, the herald bard of Oswestry, who was a pupil of Wiliam Llŷn, another of Gruffudd Hiraethog's pupils (ff. 4-6 verso, 101 verso-148 verso).
