This brown leather notebook contains diverse notes on geology and social issues, as well as material gathered for publication in 'The Principles of Geology' on submarine currents. There is no inscription on the cover. The front page is missing, and there is what seems to be a child's drawing of an insect on p. 61.

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.
