The contents of the manuscript are as follows:
(i) A copy, in a hand of the late 17th century, of the `Memoirs` of Walter Pringle (folio 1). These were first published in 1723 from a copy of the original manuscript by James Pringle of Greenknowe, 1684. The relationship of the present manuscript to that copy is unknown.
(ii) A detached leaf, headed Section XIX and paginated 81-82, concerning the history of Clan Chattan (folio 35). Written in a small late 17th-century hand, with a marginal instruction in another hand of the same date: `Take in this two sides agt this mark [X-shape with an upright lozenge in each section]’.
(iii) A copy by Robert Mylne, the antiquary, of the first part of `Originall and Succession of the noble hous of Drummond` by John Freebairn, minister of Madderty, 1656 (folio 36). There is no title, the work beginning on page 1 with a dedication to the 2nd Earl of Perth. This part is concerned with Drummonds in Madeira and with various digressions (on surnames, the name of Dundee, the children of David, Earl of Huntingdon, the Comyns, John Balliol). For copies by Mylne of the second part of this work see Adv.MSS.16.1.1, folios 1, 19 (to which Mylne here refers on folio 80 verso), 34.6.9, folio 45 (which may have originally belonged with this); for copies of documents relating to Drummonds in Madeira see Adv.MS.34.6.9, folio 407.
