Copy letter from Robert William Frederick Harrison, to Dr F W Edridge-Green His offer, addressed to Sir John [Rose] Bradford to make an exhibit at the approaching Soiree in connection with new facts he has discovered in stereoscopic vision, has been under consideration and before a definite reply is given, the relevant authorities would like to know more particularly in the nature of the discoveries. They feel that, if they are what Edridge-Green claims they would be more suitably announced by being made the subject of a short communication to the Royal Society, rather than by forming an item in the programme of an evening conversazione. 9 June 1914
