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.' First and Second Translations are in the Harleian Library. There is another Copy with additions by Mr Vaughan of Hengwrt.' The transcript is mostly written on one side only of the folios, leaving the other side for the many additions made by the transcriber. After f. 97 there are five leaves of additions on paper of a smaller size, and ff. 129-138 contain 'additional Proverbs by Mr. W. Langford late Parson of Llan fawr communicated by the Rev. Mr. Ball Vicar of Northop'.
This collection of proverbs is fuller than the one printed by Dr John Davies at the end of his Dictionary.
