For nearly thirty years has Mr. David Duguid been before the world as a private medium for various descriptions of spirit phenomena. He has given innumerable séances readily, without fee or desire for reward, to clergymen, medical men, artists, teachers of science, lawyers, journalists, merchants, and men and women in all ranks of life; he has sacrificed time and money in the cause which is dear to his heart, and upon which no act or word of his has ever brought a stain. These facts are well known to many, nor would it be necessary to print them here were it not for the efforts made to destroy public confidence in the facts brought to light through his mediumship by writers in certain photographic journals, and the artful insinuations of men who put themselves forward on the plea of being anxious investigators. _WHERE MR. TAYLOR READ HIS PAPER._ At a meeting of the London and Provincial Photographic Association, held on March 9, 1893, Mr. J. Weir Brown in the chair, the following paper by Mr. Taylor was read by him, and, with his consent, is reprinted from the _British Journal of Photography_ (Vol. XL., No. 1715, March 17, 1893). There was a large attendance of members, and several visitors were present. Visitors were allowed to make remarks, a privilege of which several availed themselves. Some members put questions to Mr. Taylor on points of detail regarding his experiments, all of which he replied to frankly and explicitly. In replying to one member, Mr. Taylor stated that he had received a letter, asking him to bring a reasonable man with him _to witness_ his experiments—in fact, he said, he had the option of taking any one he chose. To another member Mr. Taylor replied that he himself placed the sitters and the camera, and also arranged the lighting of the room. Several members spoke highly of Mr. Taylor’s qualifications to conduct such experiments; but as they could not accept the spiritualistic hypothesis, and as the photographs had to them the appearance of being copied from cut-out prints, or made by “stump-work,” they concluded that therefore they could not be genuine, ignoring entirely Mr. Taylor’s emphatic statements, which he had already given in his paper, viz.:— “_My conditions were entirely acquiesced in_”—that I “_should use my own camera and unopened packages of dry plates, purchased from dealers of repute, and that I should be excused from allowing a plate to go out of my own hand till after development_,” and that “_I should dictate all the conditions of operation_.” As a matter of fact, everything connected with the experiments was subject to Mr. Taylor’s entire control and approval. “SPIRIT PHOTOGRAPHY,” WITH REMARKS ON FLUORESCENCE.[3] _By_ J.
