This dark red Notebook starts in London with Mary and Leonard Lyell, and documents travels in Pembrokeshire, Wales, with an index created by Arabella Buckley. Lyell studies submerged forests, beaches, caves and iron works making notes and sketches, and referencing experts as well as local guides. Several meetings 'with Darwin'. Final pages relate to Grindle Pit, Bury St Edmunds, with sections written by Buckley that appear to be dictated by Lyell.

The following table of contents is Lyell's secretary Arabella Buckley's own words transcribed from digital surrogates using the platform Transkribus. Dates are indicated by adding [th] or [st]. 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 [?...]. The inclusion of [sic] indicates the misspelling of a word is deliberate and taken from the notebook.'Do' and " are replaced by 'ditto'. Brackets () indicates Buckley's own use of brackets
