Extracts, in the hand of Walter Davies, from Cyfrinach Beirdd Ynys Prydain, possibly made from the original draft written by Edward Williams (Iolo Morganwg); and notes by Walter Davies entitled 'Sylwadau ar ba Gyhydeddau a Mesurau y canent y prif-feirdd', and based on a study of the earlier Welsh poetry printed in the first volume of The Myvyrian Archaiology of Wales.
