Ffeil 99E. - Llyfr dewiniaeth,

An incomplete manuscript of texts and tables on astrology and witchcraft and medical and other recipes in the hand of 'Dauidd Dafis', 1804. The following are some examples of the titles included in the volume - '... y Deuddeg Arwydd', '[D]rych wynebau', 'Tabl i wybod pa Flauned a Riwlia Bob awr Dros Byth', 'Hyfforddiad i alw Ffasiwn ar ysbrydion a elwir Tylwyth Teg', 'Y Ffordd ar modd I gaul Trysor giddiedig a ffotho wedi Ei gadw oddiwrth iws Dun', 'Ffordd i alw math ar ysbryd a elwir ysbryd Brestt', 'y Ffordd i Ddwad i hyd i Leider a Ddygo Riwbeth oddi arnoch chwi ...', 'ffordd i wneudd Temting Powder i Beri Cariad', 'Dyma Ddeuddeg rhinwedd Croen neider', '... y Graddau', 'Dyma Deyrnasiad y plaunedau', 'Rhod Pithaoras', 'L[l]yfr Ew. Daflus i adnabod Dun wrth i wyneb...', etc. The manuscript is imperfect at the beginning (pp. 1-12 wanting) and probably also at the end (pp. [74] - ). There is a fragment of a late 19th century transcript in the form of an insert, and also three charms in other hands which have been bound into the volume.
