Letter from J A [Joseph Alfred] Hardcastle, The Dial House, Crowthorne, Berkshire, to 'Dear Uncle Willie' [Sir William James Herschel] He thanks his uncle for the letter saying that he is having the Jacob [Herschel] letters copied, but wonders if this is not a duplication of effort; even though Dr Dreyer would be happy to have clear writing. He thinks Dreyer should make his selection first and William would be able to say if he thinks any are indiscrete. Dreyer is an experienced biographer and would not choose badly. 22 May 1910
