A fine lithographic map of the county of Surrey coloured geologically. The Holmesdale Natural History Club was founded in 1857 in Reigate to ‘promote the study of natural history, local history, archaeology and geology in the vicinity of Reigate’ (Holmesdale Natural History Club), it still exists today. This map was published for the Club circa 1863 at the time the ‘Flora of Surrey’ by J A Brewer was published by John Van Voorst in 1863. It is included in that work, however being duodecimo in size, it is usually folded numerous times. Here it is unfolded. Van Voorst was active in Paternoster Row, London around 1860. The same map is also found highlighting the botanical divisions of the county, it is not recorded which appeared first. Not in Tooley’s Dictionary.
