This brown leather notebook contains geological notes on Scottish and Yorkshire geology, Edinburgh and Forfarshire, Newcastle and York. The index is adhered to the back cover, the front cover reads 2.4. The two has been struck through.

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.
