This brown leather notebook contains Lyell's notes, queries, and references to other works and geologists. The notebook also contains sketches, and notes are in pencil and ink.

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.
