This black leather notebook contains notes from Charles Lyell on geological observations in Britain, Paris and Neufchatel. Adddresses of correspondents are throughout the notebook, and referenced in Lyell's Own Index. The index is pasted to the back cover, and the front cover reads "No 58, July + August 1835, Paris + Neufchatel".

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.
