This brown leather notebook contains geological descriptions, identifications, daily logs, and sketches from field trips in Prussia and Bavaria. Notes are made primarily in pencil. The cover reads August 1833, and the Index is pasted to the back cover.

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.
