The contents of the manuscript are as follows:

(i) `Scotia illustrata sive Theatrum Urbium, Arcium, Monasteriorum et aedium quarundam illustrium in Scotia`, circa 1692. The Latin text by Sibbald intended for John Slezer`s ‘Theatrum Scotiae’. It is very different from the published text which Slezer had had translated without Sibbald`s authority. The preface is in Slezer`s hand, and each entry is signed by both Sibbald and Slezer. (Folio 1.)

(ii) Copy of William Harvey`s description of the Bass Rock. See his ‘Opera omnia’, pages 221-222. (Folio 43 verso.)

(iii) `Of Ancient Scotland`. Eight chapters in Slezer`s hand. Each page is signed by both Sibbald and Slezer. (Folio 44.)

(iv) Latin verses, copied from one of Sir Robert Cotton`s manuscripts, which were spoken at a feast in the time of Queen Mary. (Folio 48 verso.)

(v) `Dionisij Alexandrini Περιήγησεος seu orbis descriptiones versiones quatuor Latinae`, with extracts from printed works, 1709. Folios 53 verso-54 verso contain notes taken from ‘Thesaurus Geographicus’. (Folio 49.)

(vi) `Historia rerum in Scotia naturalium`, book 1. From the preface it appears that this work was intended to be very similar to Sibbald`s ‘Scotia Ilustrata sive prodromus historiae naturalis’, but book 1 consists of a survey of the different areas of Scotland with special reference to their natural resources. (Folio 57.)

(vii) `Notae in Antiquam Tabulam insularum Britannicarum`, a comparison of five editions of Ptolemy. The table of contents lists 30 chapters, but the text breaks off in chapter 3. (Folio 82 verso.)

(viii) `Exercitationes Historicae`. A list of chapters in the first of four books on Roman Britain. (Folio 94 verso.)

(ix) `Scotiae chorographia brevis` in three chapters. The text ends `haec pro brevi Regionum et Insularum Scotiae Chorographia sufficiunt, fusior explicatio in majore opere meo habetur`. (Folio 97.)
