This brown marble notebook was kept during Lyell's trip from, Radicofani to Ischia. Notes were made mostly in pencil, drawn over with ink in faint spots, and writing is often only on one side of the page. There are many illustrations with descriptions. Buckland is mentioned on p. 110, Voltaire on p. 163.

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.
