The volume consists of a collection of copies and extracts of charters and other formal documents dating from the early 14th to the early 18th century from the Register of the Great Seal and the Records in Chancery (folio 2), an appendix concerning certain Scottish peerages (folio 63 verso), a list of the Parliaments of England and of Great Britain (folio 96 verso), names of Scots Representative Peers who sat in the House of Lords in the 18th century (folio 97 verso), and an index to the titles in the collection (folio 103). Most of the leaves of the text are ruled and contain headings partly in red; folios 69-93 are blank.

The particular purpose (doubtless legal) for which this work was compiled is not known, nor whether this is a copy of an earlier work or an original compilation.
