Two notebooks in the autograph of John Jones ('Myrddin Fardd') containing transcripts of 'cywyddau', etc. by the following poets: Wiliam Llyn, Huw Llyn, Morys Dwyfech, Lewis Daron, Sion Wyn Owain, Kadwaladr Kesel, Huw Machno, Edmwnd Prys, Sion Philipp, Gruffydd Phylips, Huw Pennant, Lewis Menai, Wiliam Kynwal, Rissiart Philip, Richard Kynwal, Rhus Kain, Howel Reinallt, Sion Brwynog, Watkin Klewedog, Morgan ap Huw Lewis, Inco Brydydd, Dafydd Na[n]mor, Gruffudd Grug, Iolo Goch, Owain Waed da and Llywelyn Goch ap Meurig hên. Nearly all the poems are eulogies of, or elegies on , persons from Llŷn and Eifionydd. On the first page of MS 507 is the following note by J. H. Davies: 'Codwyd o lawysgrif Mr J. Glyn Davies ? Gan Myrddin Fardd' and it seems probable that the contents of MS 507 and the first ten items in MS 508 were transcribed from J. Glyn Davies MS 2 (though not in the same order), perhaps with a view to publication. The remaining poems appear to have been transcribed from various sources, including Cwrtmawr MS 454. Pasted in after the poems in MS 508 are two newspaper cuttings relating to 'Phylipiaid Ardudwy'.
