The picture on page 83 represents Mr. Stainton Moses and a figure unknown to him. The accomplished Editor of _Light_ is best known to the public as M.A. Oxon. The Rev. Stainton Moses, a graduate of Oxford University, was for many years Classical and English master at University College, London. From his investigations he became convinced of the general truths of what is vaguely called Spiritualism, and has devoted himself for some twenty years to making the public familiar with the higher aspects, while warning them against its ridiculous, dangerous, or degrading tendencies. The only interest of the photo is that it was taken under all those strict test conditions which I have alluded to above in this open letter. The chief professional spirit photographers are M. Buguet, of Paris, frightened by the priest into a recantation of his spirit photos, which recantation no one who tested Buguet believes any more than does Buguet himself; Mr. Hudson, who was, I am told, not always above suspicion, but, like other mediums, was also successful under rigid test conditions; Mumler, Beattie, and many others I know nothing about. Mr. Stead is now occupied in testing spirit photography, and that being the case, we are soon likely to hear more about it from an abler pen than mine. So great was the interest shown in the labelled spirit photos and the spirit drawings by the late Mrs. Watts, daughter of William and Mary Howitt, exposed in my vestry, St. James’s, Westmoreland Street, Marylebone, that I kept them up for a second Sunday. There is nothing like publicity as a means of getting at truth. Let in the light! Sift facts! “Prove all things; hold fast that which is good.”—1 Thess. v. 21. [Illustration: MR.
