This red leather notebook contains Charles Lyell's notes and contain specimen lists, queries for colleagues, and notes on publication of new editions of Principles of Geology and Elements of Geology. Subjects are chiefly notes on fossil shells of Crag. The index is on p. 138-139.

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.
