GB-110/JES/COR/4/105, The Linnean Society of London
Summary:

Tried to call on Smith to discuss the 'Polypodium cristatum' he sent to [James] Sowerby and other dried specimens he now submits for inspection, inlcuding 'Aspidium cristatum'. Unfamiliar with [William] Withering's 'Polypodium spinulosum' but concludes that the "Holt-fern" is distinct and previously undiscovered in East Anglia, concern that its habitat may be destroyed within a few years by turf-cutters and the approaching banks of recent enclosures.
