It was during the South African War that my father obtained one of his best authenticated spirit photographs, so I think that it is well to give here his own account of his experiments in that direction. He writes: "While recording the results at which I have arrived, I wish to repudiate any desire to dogmatize as to their significance or their origin. I merely record the facts, and although I may indicate conclusions and inferences which I have drawn from them, I attach no importance to anything but the facts themselves. "There is living in London at the present moment an old man of seventy-one years of age, a man of no education; he can write, but he cannot spell, and he has for many years earned his living as a photographer. He was always in a small way of business, a quiet, inoffensive man who brought up his family respectably, and lived in peace with his neighbors, attracting no particular remark.... "When he started in business as a photographer it was in the days when the wet process was almost universal, and he was much annoyed by finding that when he exposed plates other forms than that of the sitter would appear in the background. So many plates were spoiled by these unwelcome intruders that his partner became very angry, and insisted that the plates had not been washed before they were used. He protested this was not so, and asked his partner to bring a packet of completely new plates with which he would take a photograph and see what was the result. His partner accepted the challenge, and produced a plate which had never previously been used; but when the portrait of the next sitter was taken, there appeared a shadow form in the background. Angry and frightened at this unwelcome appearance he flung the plate to the ground with an oath, and from that time for very many years he was never again troubled by an occurrence of similar phenomena. "About ten years ago he became interested in spiritualism, and to his surprise, and also to his regret, the shadow figures began to re-appear on the background of the photographs. He repeatedly had to destroy negatives and ask his customer to give him another sitting. It did his business harm, and in order to avoid this annoyance he left most of the photographing to his son. "I happened to hear of these curious experiences of his and sought him out. I found him very reluctant to speak about the matter. He said frankly he did not know how the figures came; it had been a great annoyance to him, and it gave his shop a bad name. He did not wish anything to be said about the matter. In deference, however, to repeated pressing on my part, he consented to make experiments with me, and I had at various times a considerable number of sittings.
