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.

The remainder is in several hands of the late seventeenth or early eighteenth century. There are copious annotations by William Maurice and some additions and annotations by Cadwaladr Dafydd, Llanymowddwy (1747) and L[ewis] Morris ('Llewelyn Ddu o Fôn', 1701-65).

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)

The remainder of the volume contains further verse items including items with the superscriptions 'Gwybodau - Celfyddyd', 'Trioedd Iolo Morganwg', 'Gwasgaredd Doethineb, yr ail Gwlm', 'Pennillion, Englynion, Dernynau Iolo Morganwg', 'Englynion mawl i Dduw am waredigaeth o dwyll y Byd', 'Englyn i chwaldodwr disynwyr', 'Cynghog', 'Englynion y Wawr', 'Englynion Pwnc Eisteddfod Aber Cwm y Fywch, 1771', 'Englyn i Gybydd', 'Englynion i Gymdeithas o Rithgrefyddwyr mewn Ile nid rhaid ei enwi ym Morganwg', 'Englyn i For gerwin temhestlog', 'Pennill i Rithgrefyddwyr Aberthin', 'Pennillion Iolo Morganwg', 'Dechreuad Bonedd', 'Englyn i Dai Gwynnion Morganwg', 'Englynion ar dorriad allan y Rhyfel yn 1802', 'Englynion diweddglo'r salmau ac eraill amrafaelion', 'Beirdd', 'Cân Lewys Gabriel', 'Hymn i Sior y Crinwas' (this poem attributed to Bleddyn bach ap y Gwir), 'Englynion ar Undod Duw', 'Pennill a gant y Bardd iddo'i hunan', 'Cynghor hen gybydd ar ei wely angau iddei Fab o Ladin Horad', 'Beddwers Sior y Crinwas', 'Englyn i Hen ferch afrywiog dros ben', 'Englynion i'r Fronfraith', 'Trioedd yr offeiriad a gant Iolo Morganwg yng Ngorsedd yr Alban Hefin ar ben y Garth ym Morganwg, 1797', 'Englyn a feddyliwyd ei roddi ar faner Rhyddfilwyr Morganwg', 'Can a wnaed yn y flwyddyn 1777 y Bardd yn dychwelyd i Forganwg wedi bod flynyddau lawer yn Lloegr', 'Beddbennill', 'Englynion y Gwynt, 1770', 'Breiniau Dyn' (two versions), 'Hymn undodaidd', and 'Casgliadau o'r Gwasgaredd at y Doethineb Teu[lu]aidd' besides items without titles or superscriptions. There is an English stanza entitled 'Epitaph on the Sexton of Cowbridge' on p. 230. The few prose items in the section from p. 203 onwards include a brief note relating to a specific type of poetic exercise at 'eisteddfodau' in Morgannwg (pp. 223-5), a brief note in connection with a psalm composed on the occasion of opening a Berean meeting house (Ty Cwrdd Berea) (p. 229), and a list headed 'Llyma'r achos y rhoes Duw ei fendith i Ddyn' (p. 283). 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 note-book (pp. 1-80) and miscellaneous papers (pp. 81-268) containing notes, lists, extracts, transcripts, etc., in the hand of Edward Williams ('Iolo Morganwg') bound together in one volume.
