Some investigators seem to think that the same spirit forms ought not to appear on plates with different people, and that if they do so the circumstance warrants suspicion, if it is not even a proof of fraud. This is an entire mistake, and a mistake which can only be made by those who have not investigated the matter in a practical manner for any considerable length of time. Apply the same reasoning to materialisation, or to direct spirit writing, and see what it will lead to. Mr. E. A. D. Opie, of Adelaide, in a lecture on “Spirit Photography,” delivered on July 1st, 1891, before the Adelaide Spiritualistic Association, made this remark: “It is necessary to accept all second-hand reports of this phase of Spiritualism with more than usual reserve, as, in one instance at least, I have discovered, on comparing reports of the obtaining of the same picture by different people.” Mr. Opie in these words probably expresses an opinion held by many others, held in London as well as in Adelaide. And what are we to infer from it? That if two sitters get on their plates a picture of the same spirit form, it will be a proof of fraud? Not at all. Of course, if the pictures have been produced by a dishonest operator, they may be fraudulent. That is not a thing to dispute. But the fact is that there are in existence a number of genuine spirit photographs in which the same abnormal images are found with various sitters. Most of these have differences in size, in attitude, and in spirit drapery on the forms, but the likenesses are identical. Some of them have been taken in different places, with different cameras, with plates purchased in different cities and used by careful investigators. Mr. Opie’s lecture was published in Adelaide as a pamphlet of twenty-two pages; it is the result of much reading, and it is but fair to Mr. Opie to note that he had no practical acquaintance with the subject. * * * * * Mr. Parkes gave some séances in 1875 in Mr. Burns’s rooms, 15 Southampton Row. On one occasion three sitters got spirit forms on three plates. At the same meeting I requested that I might be photographed. A clairvoyante sitting near me said I ought to get something good, for she could see a number of spirits near me. When the plate was developed there were eleven spirit forms on it. * * * * *
