288 THE LAW OF PSYCHIC PHENOMENA.
the percipient was in a completely normal condition, and saw the visions objectively. Moreover, the phenomena of so-called spirit photography amply demonstrate the fact that visions can be created of such tangible character that they can be caught and fixed upon the photographic plate. In saying this I am not insensible of the fact that many frauds have been committed in this species of phenomena, as well as in all others attributed to spirits of the dead. But this does not militate against phenomena of that character which have been produced under test conditions so strict that all possibility of fraud was eliminated. In admitting this class of phenomena to be genuine, in the sense that it is sometimes produced without fraud or legerdemain, it is also admitted that, in many instances, pictures of the sitter's dead friends have been produced which were such perfect likenesses of the deceased as to be unmistakable. Of course it will be understood that whilst I admit the phenomenon, I do not admit the claim that it has its origin in the spirit-world. Like all other so-called spirit phenomena, it is, in my opinion, directly traceable to the power of the subjective mind of the medium, aided by telepathic communion with the sitter. The latter, consciously or unconsciously, thinks of one or more of his dead friends. The medium, perceiving telepathically the image created by the mind of the sitter, re-creates it in such tangible shape that it is caught by the camera. Or it may be in some instances that the image is created by the sitter himself in such palpable shape as to be caught by the camera. Indeed, in many recorded instances, where the sitter has been a powerful medium, it seems probable that he created the image himself. In point of fact there is little doubt that the power resides, to a greater or less extent, in all human beings to create such images, their strength and clearness depending, of course, upon the power of the individual to recall vividly the remembrance of the person to be photographed, together with the power to concentrate his mind for a certain length of time upon the mental picture. Indeed, experiments have been made which demonstrate the
