V, t. 158 infers that the whole volume is in the hand of the aforementioned Jenkin Richard(s).

A small volume containing Welsh poetry in strict and free metre written in a mid- seventeenth century hand [not that of Wiliam Phylip the poet]; the date 1676 (p. 22) is probably later than the manuscript itself. The poets whose work is represented are Iolo Goch, Will: Phylip, Hunffrey [sic] d'd ap Euan 'y clochydd' / 'clochydd o lanbren mair', and Doctor Siôn Cemp [sic].

A volume written in several hands of the seventeenth century and containing Welsh poetry mainly of a religious nature in strict and free metre ('cwndidau', 'cywyddau', 'penillion', etc .), a few medical and veterinary recipes, some in English, Welsh triads (f. 33 verso, 'llyma drioedd pawl'), and (ff. 36 verso, 40 verso) two items of religious verse in triplet metre in English. The poets whose work is represented are Thomas Lle'n (Thomas Lle'n Daio Pwel), Lle'n Daio Pwel, Thomas ap Ieuan ap Rys, Siankin Thomas, Gronw Wiliam, Davydd ap Risiart, Howell Siankin, Ieuan ap Rys 'o verthyr kynon', Wiliam Prys, Sion Siankin 'o benllin', Ll'n Sion, Sion(n) y Kent, Thomas Harry Morgan, Rys Goch, Howel Swrdwal, Iolo Goch, Howel D'd ap Ieann [sic] ap Rys, Davydd Ddu Hiraddig, Sion Tydr, Risiart D'd, Rees Pritchard (Rhys Prichard), Watkin Powell, and Jenk: [Richard]. Ff. 42 recto-69 verso contain poetical compositions by Rhys Prichard ['Yr Hen Ficer'], one dated 1616, and someone has supplied page references (in pencil) where possible to [Y Seren Foreu, neu Ganwyll y Cymry. Gan Rhys Pritchard A.M. . . . (Llanymddyfri: Rhys Tomas, 1770)]; there are, however, some differences between the manuscript and the printed text and not all the items in the manuscript are to be found in the printed volume. The handwriting of ff. 73 recto-74 verso is the same as that of NLW MS 13072B and I. A. Williams MS 7 and the contents of these pages relate in part to the year 1660. The last item in the volume is an incomplete copy of a long series of religious 'englynion' according to the letters of the alphabet by [Lewis Glyn Cothi]. There are a few annotations by Edward Williams, 'Iolo Morganwg', and a piece of paper bearing the name 'Taliesin Williams (Ab Iolo)' has been pasted in at the beginning of the volume.

Fuller details have been placed with the manuscript.
