This brown leather notebook contains watercolour geological skylines. Loose leaf pages in the middle of the notebook list recipients of copies of 3rd and 4th editions of Principles of Geology; queries for M Graves, notes on 3rd edition, and queries for Deshayes. There are also cross-sections and fossil drawings. The front cover reads December 1832, and the index is pasted to the back.

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.
