This dark leather notebook contains Charles Lyell's notes which appear to be continuation of discussion on Touraine shells, notes of list of books to go to America, notes on correspondence sent and received, and notes on lectures. On p. 106 Lyell makes reference to Timothy Abbot Conrad's New York Geological Survey of 1840. The covers of the notebook are blank, the index is written on the last pages of the book.

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.
