A manuscript in two parts, the first part containing 'Some words omitted in Dr. Davies Welch and Latin Dictionary ...'; and the second part containing 'Geiriau or hen Gamberaag anhawdh ei dirnad yn yr oes hon', with illustrations from the poets, including Tudur Aled. The first part of the text (original foliation 1-101) is written in a seventeenth century hand while the second part (original foliation 1-14) is written in a sixteenth century hand.
From the many references in the text to Sir Thomas Wiliems it would appear that the scribe of the first part of the manuscript had access to the original Dictionary MSS used by Dr John Davies, Mallwyd. The vocabulary in the second part of the manuscript is apparently a copy of Wiliam Llŷn's Vocabulary.
