Letter from J A [Joseph Alfred] Hardcastle, The Dial House, Crowthorne, Berkshire, to 'Dear Uncle Willie' [Sir William James Herschel] He asks if Etchell photographed [the portrait of ] Caroline [Herschel] by [Martin Francois] Tieleman. He would like a dozen prints as he already has the pastel and Artaud. These will be needed for the Herschel Papers publication and he wonders if the Etchell negatives will serve. 31 October 1911
