Copy letter from Robert William Frederick Harrison to G P Grace, 160 The Grove, Camberwell, SE 'I have to acknowledge the receipt of your letter of the 12th instant, enclosing six photographs of the Moon, and to say that they cannot be received by the Society except through one of its Fellows. I am at the same time to inform you that the Secretaries of the Society do not consider the subject dealt with in your letter suitable for communication. I therefore return the photographs.' 15 February 1912
