The volume contains three sections, written by different persons.
(i) The Law Repertory of Sir Thomas Wallace of Craigie (folio 1). The text contains several differences from the copies of this work in Adv.MS.24.3.2 and MS.943. In other hands, some more modern, are: a note stating that the work 'is thought to have bein done by Sir Thomas Wallace of Craigy, lately on of the Lords of Session, & compiled by him for his readier use when he was ane Advocat' (folio 1); occasional marginal and interlinear notes; a general criticism (folio 191 verso); and an index (folio 193).
(ii) Copies of Acts of the Scottish Parliament and Privy Council, proclamations, protestations, official letters, etc., 1579-1663, with a list of the Scottish nobility, 1671, preceded by a list of contents (folio 198). The text is concluded in another hand, probably of the early eighteenth century.
(iii) Note of the writs produced by the Scottish nobles in support of their claims to precedency in 1604, and relevant material. (Folio 277.)
