This notebook contains field and travel notes by Charles Lyell while in North America, traveling between Philadelphia and Boston. There are multiple sketches and sections of geological formations, notes of lecture tickets and items 'to do' on certain dates, notes referring to lectures attended, and items borrowed.

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.
