This smaller, thinner notebook with a marbled cover contains notes during Lyell's trip from Florence to Radicofani, mostly illustrations and field notes of cross-sections, labeled, and some descriptions and queries. The front plate reads "No 3 Italy 1828 Florence Oct 13th to Radicofani Oct 15th".

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.
