This tan leather notebook contains Charles Lyell's notes from his North American tour of New York, including New York City, Albany, Syracuse, Rochester. Notes are predominantly pencil, some ink, a mixture of field notes and travel notes. The index is located at the back of the notebook, both covers are unmarked.

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.
