The inscriptions on p. 81 and p. 83 and the note on p. 82 appear to indicate that they were intended as cover and 'title-page' respectively for a home-made booklet containing a corpus of 'englynion' by Jenkin Richards of Blaenau Gwent, co. Monmouth, extracted mainly 'o Lyfrau Harri Siôn o Bont y Pwl a Llyfr ym Meddiant Rhys Thomas, Argraffydd o'r Bont Faen ym Morganwg', but only four 'englynion', presumably meant to be attributed to this poet, follow on p. 84. Pp. 91-198 contain miscellaneous items including 91-2, notes headed 'On the oldest places of Christian Worship in Wales'; (continued)

93-7, 105-06, notes, generally derogatory, on the character and literary and metallurgical activities of Lewis Morris; 100- 04, notes on 'Welsh Ideas of Celibacy'; 122-8, a transcript of thirty 'englynion' entitled 'Ymatreg Llywelyn a Gwrnerth' attributed to Tysiliaw fab Brochwel Ysgithrawc; 130, a note relating to an 'eisteddfod' held at Y Pil (Pyle, co. Glamorgan), 1740; 131- 41, notes relating to 'singing to the harp', the 'bardd telyn', carol and 'alsain' verse, the adapting of verse to music, etc.; 147-62, transcripts of 'englynion' attributed to Rhobert, Tywysog Norddmanty, Morys Kyffin, Wm. Byrchinsha, and Gutto'r Glyn, extracts from the works of various Welsh poets, etc.; 167, a version of William Midleton's introductory epistle [to his Bardhoniaeth neu brydydhiaeth, y llyfr kyntaf (Llundain, 1593)] copied 'Ex Vol. 40. Mr. Panton' [i.e. Panton MS.40 now NLW MS 2008]; 168-9, five stanzas of a hymn tune attributed to Elis Wynn; 169, a transcript of two 'englynion' attributed to Dr. [John] Davies; 171, a list of the commotes and hundreds of Glamorgan copied from '68. P.P.' [i.e. Panton MS 68 now NLW MS 2034]; 175-88, an alphabetical list of Welsh bards 'o Lyfr D'dd Ddu o'r Eryri'; and 188-98, miscellanea including transcripts of 'englynion' attributed to Siôn Mawddwy, Ieuan Tew, William Philip, and D[afydd] ab Gwilym, miscellaneous triads, genealogical data relating to various Welsh bards and Syr Rhys ap Thomas, etc. Pp. 207-390 (previously paginated 1-184) contain a collection of maxims, proverbs, triads, sayings, etc., attributed to Cattwg Ddoeth and described on a 'title-page' to the section ( p. 199) as 'Llyma Ddoethineb Cattwg Ddoeth o Lancarvan' and in a concluding note (p. 390) as 'Llyfr y cyntaf y Gwyddfardd Cyfarwydd'. In a note on the aforementioned 'title-page' (p. 199) Edward Williams claims to have transcribed this collection in 1799 from a manuscript in the possession of Siams Thomas of Maerdy Newydd, co. Glamorgan. Preceding and following the actual text of the collection are transcripts of a prefatory letter dated 1685 (pp. 201-06) and of the concluding note already referred to (p. 390) both of which are attributed to the Glamorgan scribe and copyist Thomas ab Iefan of Tre Bryn as compiler of the manuscript from which Edward Williams was allegedly copying (see TLLM, t. 172; IM, tt. 291-4). Pp. 391-477 contain a transcript of a collection, in alphabetical order, of over three thousand Welsh proverbs attributed to Cattwg Ddoeth ('Llyma Ddiarhebion Cattwg Ddoeth . . . sef yw hwnn Ail Lyfr y Gwyddfardd Cyvarwydd'). This collection, according to the aforementioned note at the end of the preceding section (p. 390) attributed to Thomas ab Iefan, had been compiled by the said Thomas from various sources and formed a continuation of the previous section. Edward Williams's claim with regard to the Siams Thomas volume is probably intended to apply to the contents of pp. 391-477 as well. The contents of pp. 199-390 have been published in The Myvyrian Archaiology of Wales . . ., vol. III (London, 1807), pp. 1-99.

A composite volume in the hand of Edward Williams ('Iolo Morganwg') containing 'cywyddau', 'englynion', etc., by Edward Williams himself, and a further corpus of unattributed poems, mainly 'cywyddau' and 'englynion', which are also probably the work of the said Edward Williams. Also included are two 'englynion' and one further stanza attributed to Taliesin ab lorwerth or Taliesin ab Iolo Morganwg, and scriptural extracts.

Pp. 165-6 contain a list of two hundred and forty-six 'cywyddau' attributed to D[afydd ap] G[wilym].

An imperfect manuscript consisting of thirty folios of uniform size and two smaller leaves, with the two halves of ? the lower cover of an early nineteenth century periodical or part publication, which at one time seems to have served as a protective covering, bound in at the beginning. A considerable part of the original manuscript appears to have been lost as the volume was described by the Reverend John Williams ('Ab Ithel'), circa 1856, as containing 'about 100 pages' (see L. James: Hopkiniaid Morganwg . . . (Bangor, 1909), p. 91). The former protective cover bears the inscription 'Llyfr Llanfihangel Iorwerth. Cywyddau amrafaelion. Siôn Cent hyd Dafydd Hopcin o'r Coetty. Englynion Eiry Mynydd, &c.', in the hand of Edward Williams ('Iolo Morganwg'), and the contents consist of transcripts of Welsh verse mainly in strict metre. Dafydd Hopkin of Coety, co. Glamorgan is sometimes named as the copyist (see L. James: op. cit., p. 91; TLLM, tt. 229, 267; and IMCY, t. 139). The poems include 'cywyddau' and 'englynion' by Thomas Prys, Ieuan Tew Brydydd, Dafydd Hopkin (1734), Ieuan Brechfa, Lewis Morganwg, Iorwerth Fynglwyd, Dafydd ap Gwilym, Rys Dynfwal (sic), Rhys ab Morys, ?Mredydd ap Rees, Swrdwal Hen, Huw Dafydd Probert, Siôn Tudur, Owain Gwynedd, Gwilim ap Ieuan Hen, Dafydd ap Edmwnt, Daio Lliwiell, Ieuan Tew Brydydd Ifangc, Huw Lewis, Gruffydd ab Ifan ab Llewelyn Fychan, Wiliam Cynwal, Morus ab Hywel ab Tudur, Siôn Cent, Hywel ab D'd ab Ieuan ab Rhys, Llywelyn Goch, Gruffydd Dafydd Fychan, Ieuan ab Hywel Swrdwal, Bleddyn Fardd, and Dafydd Llwyd Fach, a series of pseudo- gnomic poems with each stanza commencing with the words 'Eira mynydd' some of which are attributed to Llywarch Hen and Mabclaf ab Llywarch, and poems attributed to Taliesin and Aneurin. There are marginal notes by Edward Williams and his son Taliesin Williams.

A composite volume in the hand of Edward Williams ('Iolo Morganwg') the contents consisting almost entirely of Welsh free- and strict-metre verse, the latter being mainly in the form of 'englynion'. Most of the verse items, whether single stanzas, multi-stanza poems, or sequences of stanzas, bear the name of the said [Edward Williams] 'Iolo Morganwg', and all are probably his work. Many are in an incomplete form. Pp. 1-16 contain a copy of a proposed preface or foreword to a collection of poems which [Edward Williams] 'Iolo Morganwg' apparently intended to publish in 1809 (see IM, tt. xliv-xlv), and this is followed on pp. 17-88 by verse items including items with the titles or superscriptions 'Gwasgaredd Iolo Morganwg', 'Anneddfoldeb', 'Dyn ymguddgar', 'Cwyn Clwyfus', 'Dyriau Gwasgar', 'Pennillion diarhebol Iolo Morganwg', 'Pennillion serch gwasgar', 'Darnau Defnyddion Doethineb Teuluaidd', 'Cynghor', 'Tribanau', 'Pennillion 1805', 'Doethineb Teuluaidd sef Pennillion Diarhebawl', 'Salm 105', 'Canu Gwashaela Sir Gaer', 'Emyn Dydd Barn', 'Emyn Angladd', 'Salm 104', and 'Salm'. The upper half of p. 89 bears the inscription 'Doethineb Teuluaidd Neu Lawrol Doethineb sef Egwyddorion Dyled at Dduw a Dyn ar Fesurau cân rhwyddion ac mewn Iaith esmwyth hawdd ei dealt Er addysg i'r Ieuainc a'r Annysgedig. Iolo Morganwg ai cant' which is followed on the lower half of the page by three stanzas of verse and on pp. 91-2 by nine stanzas of an incomplete poem. On p. 95, which was possibly a 'title-page' for the section now paginated 99-138, is a variant version of the aforementioned inscription reading 'Doethineb Teuluaidd ar Fesurau cerdd rhwyddion ac mewn Iaith esmwyth Er hawsder dealt i'r annysgedig a'r Ieuanc. Iolo Morganwg ai cant', two stanzas of Welsh verse by 'Iolo Morganwg', a Latin quotation from the works of Seneca, and the date 'Alban Eilir 1807'. This is followed on pp. 99-131 by poems with the superscriptions 'Doethineb Teuluaidd. Trioedd Doethineb', 'Gwersi Doethineb sef Gwasgaredd Doethineb. Y Cwlm Cyntaf', and 'Gwasgaredd Doethineb. Yr ail gwlm', and thirty-nine stanzas without a superscription. Pp. 139-40 contain miscellaneous stanzas headed 'Gwasgaredd Iolo Morganwg' and pp. 143-4 a sequence of stanzas headed 'Cynghorion gwasgaredig o'r ysgrythurau'. P. 147 is inscribed 'Doethineb Teuluaidd Sef Caniadau Dwyfawl a Moesawl ar Fesurau esmwythion Er addysg Dwyfol a moesol I blant a Chymreigyddion Ieuainc Gan Iolo Morganwg, B.B.D.', and p. 148 contains a list of the names of, or descriptions of, eighteen poems or sequences of verse or groups of poems to be found on pp. 149-202 including 'Cân y diodydd ar hen ddiarhebion Cymreig', 'Cân y Ffermwr', 'Englynion i Ddosparth Cerdd dafawd Gwynedd' (called 'Englynion sen . . .' on p. 148), 'Ar ddiwydrwydd', stanzas without a title or superscription but listed as 'Pennillion y Trallodion' on p. 148, 'Englynion y Bedydd', 'Englynion o flaen Trioedd Pawl', 'Gwasgargerdd Iolo Morganwg', 'Salm', miscellaneous stanzas including 'englynion' and 'tribannau', 'Gwasgaredd Iolo Morganwg', 'Tribanau' (listed as 'Tribanau Gwasgargerdd' on p. 148), miscellaneous 'englynion' including two relating to 'awdlau' submitted at an 'eisteddfod' held at Aberhonddi in 1822, 'I Owain Myfyr' (a bitter attack on Owen Jones ('Owain Myfyr')), 'Englynion i'r Greal a gyhoeddwyd gan Ddeudneudwyr Llundain', 'Pennillion Iolo Morganwg' (one hundred stanzas containing moral precepts), a sequence of twenty-one stanzas of a similar nature (these two series of one hundred and twenty-one stanzas are probably the ones referred to as 'Doethineb Teuluaidd (Ex Catonis Disticha de Moribus)' in the list on p. 148, see IM, t. 290), and 'Cynghor'. (continued)

P. 237 contains what appears to be a copy of a proposed title-page to a collection of poems containing moral precepts entitled 'Llawrol Doethineb Neu Doethineb Teuluaidd' composed by [Edward Williams] 'Iolo Morganwg' possibly with a view to publication in 1816.

A composite volume containing transcripts of historical and literary material in the hand of Edward Williams ('Iolo Morganwg'). Pp. 1 -74 contain one of the two known reputed transcripts by Edward Williams of the supposedly variant version of the medieval Welsh Chronicle of the Princes ('Brut y Tywysogion') which is generally known as 'Brut Aberpergwm' or 'The Gwentian Brut'. The superscription on p. 1 reads 'Llyma Vrut y Tywysogion val y bu Ryfeloedd a gweithredoedd enseiliaid a Dialeddau, a Rhyfeddodau gwedi eu tynnu or hen gofion cadwedig au blyneddu'n Drefnedig gan Garadawc Llancarfan', and, according to a note at the end of the text (p. 74), the present copy was transcribed by Iorwerth ab Iorwerth Gwilym, i.e. Edward Williams, in 1790 from one of the manuscripts of the Reverend Thomas Richards, curate of Llangrallo [co. Glamorgan], who, in turn, had copied the work in 1764 from one of the manuscripts in the possession of George Williams, esq., of Aberpergwm [co. Glamorgan]. This is substantially the text that was published in The Myvyrian Archaiology of Wales . . ., vol. II, 1801, pp. 468-582, and also in Aneurin Owen (ed.): Brut y Tywysogion; the Gwentian Chronicle of Caradoc of Llancarvan . . . (London, 1863), this second publication being accompanied by an English translation. P. 89 is inscribed 'English Translation of Caradoc of Lancarvan's Annals of the Princes of Wales. By Edward Williams. 1807. Rough Copy'. The section now paginated 101-88 contains an English translation of the text found in pp. 1-74. Other items in the volume include pp. 191-208, extracts from William Warrington: The History of Wales . . . (London, 1786); 215-19, a draft copy of the last three paragraphs of the preface to The Myvyrian Archaiology . . ., vol. II, in which the text of 'Brut Aberpergwm' was published (see G. J. Williams: op. cit., pp. 206-08); 223-5, a transcript of the opening paragraphs of a version of the Laws of Hywel Dda; and 233- 43, copies of poems by [Edward Williams] 'Iolo Morganwg'.

A composite volume consisting of a number of home-made booklets containing miscellaneous items in the hand of Edward Williams ('Iolo Morganwg') bound together. P. 31 is inscribed 'Gwallter Dymapys ar Drin Tir'. Pp. 37-52 contain a short treatise in Welsh on agricultural husbandry with the superscription 'Llyma Lyfr Gwallter Demapys [Walter Map or Mapes, the medieval author, fl. late twelfth century] sef cynghorion hen wr megis y dysgai ac y cynghorai ei ab ynghylch llafuriaw Tir a threfnu ysgrublaid fal hynn'. According to an end note (p. 52) the treatise was copied 'O Lyfr Mr. Richards o Langrallo', but for the opinion that it was compiled by Edward Williams himself and attributed to Walter Map see TLLM, t. 3. P. 53 contains a note, allegedly taken from Thomas Truman of Pant Lliwydd's book of pedigrees, linking Walter Map and his family with the village of Trewallter and parish of Llancarfan, co. Glamorgan, but for the falsity of this claim which is probably an Edward Williams forgery see again TLLM, t. 3. Pp. 54-68 contain a further treatise in Welsh on agricultural husbandry with the superscription 'Cyngor yr Hen Gyrys Megis yr oedd ynteu yn cynghori ei fab fal hynn'. This, according to a note on p. 68, was copied from a volume in the possession of the Reverend Thomas Evans of Brechfa in 1800.
