A late eighteenth and early nineteenth century manuscript of Thomas Davies containing medical recipes and prescriptions, notes on the treatment of diseases and on the virtues of herbs, and a few miscellaneous notes and extracts. The contents have been taken for the most part from printed sources but a few isolated prescriptions are ascribed to Jno. Morgans, surgeon, of St Davids, 1808 (p. 346) and Mr [Thomas] Jones, Neuaddfawr [Lampeter, Cardiganshire] (pp. 349, 357). Among some extraneous matter in the volume are 'Trioedd Offeiriaid' in 'triban' metre by Edward Williams ('Iolo Morganwg') (pp. 351-4) and a transcript of a Carmarthen Bank note, 1802. There is an incomplete index at the end of the volume.
