Letter from J A [Joseph Alfred] Hardcastle, The Dial House, Crowthorne, Berkshire, to 'Dear Uncle Willie' [Sir William James Herschel] He asks if volume one of the set of printed works on optical notes given to Oxford was in William Herschel's hand, thinking it unlikely that he broke up the set. He asks Sir William to send Dreyer a card on the subject. Dreyer mentions the main portraits of William Herschel and Alfred queries if something important has been left out. 5 February 1912
