“Five correspondents write on this head; but they only bring forward experiences of many years ago, references to the _News_ and _Journal_ of old dates, and similar evidence. The letters are interesting, but we cannot find room for a correspondence on the subject. Of testimony there is more than enough. Those who can be convinced by testimony are probably convinced already, if they have examined the subject. If the matter is to be advanced further, it must be by careful experiments under test conditions, and such experiments will not satisfy the active objectors unless they can be repeated to order, and, so far as we know, no one has claimed to be able to do this. Only new tests, well authenticated, are of use in our columns at present. Any such we are prepared to publish, with reproduction of the alleged psychic photographs if desired.” _THE REVIEW OF REVIEWS, April, 1893._ In the _Review of Reviews_[8] for April, there is a reproduction of one of the spirit photographs taken by Mr. Traill Taylor, and also of the portrait obtained by Mr. Glendinning and Mr. Duguid, without the use of a camera, and without exposing the prepared dry plate to light until after it was developed and fixed. Mr. Stead refers to Mr. Taylor as a well-known photographic journalist, of unquestionable good faith, and prints the details of the experiments as given in Mr. Taylor’s paper. Dr. Alfred Russel Wallace, F.R.S., who has had much experience in this subject, and possesses a large collection of spirit photographs, thinks the most interesting results of the recent experiments are those in which the form of one of the sitters is blended with the form of the psychic portrait; but Mr. Stead thinks the portrait obtained without the camera the most interesting. He concludes his article thus:— “Mr. Glendinning assures me most positively that the plate had not been tampered with. If so, it is to be hoped Mr. Duguid will repeat the last experiment under test conditions. It is much the most interesting of the lot.[9] “The illustrations are badly developed, but they suffice to show that the plate was sensitive to the presence of entities invisible to the human eye. Everything, of course, depends upon the accuracy and honesty of the photographer; and the reputation of Mr. Taylor and Mr. Glendinning is above reproach.” _From THE MORNING, April 4th, 1893._
