Undated, the reading material referred to dates this notebook post c.1814-1823, and the notes may be preparation for his article on 'Recent Formations in Forfarshire].Contains referenced "extracts from various Geological Works" as well as from letters. Later on in the notebook, Lyell's own observations and reading is headed at the top of the page. There is a reference to him numbering specimens [pg. 74]. A number of pages blank, paginated.
