This black leather notebook contains notes from Lyell's trip to Denmark, and from meeting with Dr. Heinrich Beck. There are also notes on scholarship and news from other notable natural history correspondents. Notes are in a mixture of pencil and ink, there are some sketches, and multiple blank pages. The index is pasted to the back page, and the front cover is blank.

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.
