This plain leather brown notebook contains notes on present and future changes, progressive development, climate in Paris, and lists to consult with Deshayes. The front cover is blank and the first few pages are missing. Lyell's notes are mostly in pen, and there are many drafts with slashes, few sketches.

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.
