This notebook, of brown leather, covers Lyell's trip from Geneva to Paris. Clearly kept while traveling, Lyell's writing orientation changes frequently, ink blotches occasionally obscure text, and illustrations are sketched amongst observations. Contents include essays on Cosmogony, 'Duration of Species', 'Uniformity', role of a historical sketch, 'Creation of Species', 'Christianity & Science'.

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.
