A manuscript containing cywyddau brud and other poetry (pp. 7-8, 13-78, 87-94, 101-111, 115-130, 135-136, 154-298), the poets cited including Taliesin, Dafydd Nanmor, Dafydd ab Edmwnd and Siôn Tudur; prophecies of Merlin (pp. 79-86, 112-114, 131-134, 137-140); two imperfect documents of the Bishops of St Asaph and Gloucester, dated 1627 and 1596 (pp. 9, 11); 'Swynion a Meddeginiaetheu'; &c.

A manuscript volume, begun in about 1709, belonging initially to an Elizabeth Salusbury, containing numerous medicinal remedies and culinary recipes (pp. 1-186, 197-236, 238-242), together with a series of 'amlegues', diagrams displaying collections of dishes for different meals (pp. 187-196, 237). The volume appears to be in at least two different hands, the second appearing on pp. 122-207 passim. The contents of pp. 1-40 are listed at the front of the volume (pp. i-iv).
Also included is a small group of loose papers, 1756-1792 and undated, some relating to the Jones family of Llantisilio Hall, Llangollen, mostly consisting of further recipes (pp. 243-276). Elizabeth Salusbury is likely the daughter of Peter Salusbury of Abergele, who married firstly Thomas Peirce of Llysvaen in 1715/6 and secondly John Lloyd of Llansilin in 1720; her daughter Mary Lloyd married Thomas Jones of Llantisilio Hall in 1740. A letter, 1756, from John Leche (p. 275) refers to 'you and Mrs Jones' and to 'good Mrs Lloyd'.
