In this green leather notebook, Lyell's notes focus on Scottish and British geology, and planning for Principles and Elements of Geology. He and Mary visit the Isle of Arran for the first time, their visit referenced in Leonard Wilson's book. Spectacular drawings of Goatfell, envisioning lava veins, as well as line drawings of the landscape. Notes are written in pencil and ink, with tables, illustrations, lists, and draft letters.

The following table of contents is Lyell's own words, copied from Lyell's own "Index", found at the beginning and end of the notebook, transcribed from digital surrogates using the platform Transkribus. When known, Lyell's abbreviations and contractions have been expanded using brackets []. When writing is unclear, and transcription is not possible, this is denoted using [...]. Quotation marks are Lyell's own notation for ditto, as is the abbreviation "d'o". The inclusion of [sic] indicates the misspelling of a word is deliberate and taken from the notebook.
