Today we have finished the cataloguing of our Darwin collection.  Almost last to be done was one of the nicest finds – offprints of two of Darwin’s early articles, on South American volcanos and Scottish geology, presented by Darwin to Charles Lyell, his friend and fellow geologist. One of them, “On the connexion of certain volcanic phenomena in South America ” is inscribed to Lyell in Darwin’s own hand. The other has pencil annotations, almost certainly in the hand of Lyell. We would like to thank the Darwin Correspondence Project, in Cambridge University Library, for reliable recognition of Darwin’s signature.
