Three folios at the beginning and two at the end contain poetry in Welsh and Latin, etc. There are also some items of a corn account. The general style of the handwriting, which is not all in the same hand, is suggestive of the manuscripts of Dr John Davies, Mallwyd, which were copied partly by him and partly on his behalf.
A manuscript in the autograph of Moses Williams containing Welsh proverbs translated into Latin. Inside the front cover is inscribed: 'Transcribed out a MS. writ by Dr Davies. The Drs.'

The transcript is mostly written on one side only of the folios, leaving the other side for the many additions made by the transcriber.

Mus: MS. 100 Harl: D. XVII. 2414'. On the front of the volume is written 'No. 25 / No. 144 Hauod [although this manuscript is not mentioned by Iolo Morganwg as among the Hafod collection] / No. 8'.
