| Date Note | Later date derived from one of the notes. |
| Description | Geological notes and one small band of colouring marking limestone, by William Buckland, [?1813-1840], on topographical base map 'A new map of South Wales by Nathaniel Coltman', published by Laurie & Whittle, 1 January 1798. Dissected on cloth, 4 miles to 1 inch. Most of the map is blank. |
| Administrative History | A later version of the base map is in the Greenough collection (LDGSL/947/6/E/2) and was used as part of the research for the Society's 'Geological Map of England & Wales' (1820, 1840). As Buckland collaborated with Greenough on the map, this item could be related. |
