right, while the sitter was from the
left; some were comely ... others not so. Some monopolized the
major portion of the plate, quite obliterating the material
sitters.... But here is the point: Not one of these figures which
came out so strongly in the negative was visible in any form or
shape to me during the time of exposure in the camera, and I vouch
in the strongest manner for the fact that no one whatever had an
opportunity of tampering with any plate anterior to its being
placed in the dark slide or immediately preceding development.
Pictorially they are vile, but how came they there?

"'Now, all this time I imagine you are wondering how the
stereoscopic camera was behaving itself as such. It is due to the
psychic entities to say that whatever was produced on one-half of
the stereoscopic plates was produced on the other--alike good or
bad in definition. But, on a careful examination of one which was
rather better than the other ... I deduce this fact, that the
impressing of the spirit form was not simultaneous with that of the
sitter.... This I consider an important discovery. I carefully
examined one in the stereoscope and found that, while the two
sitters were stereoscopic _per se_, the psychic figure was
absolutely _flat_! I also found that the psychic figure was at
least a millimetre higher up in one than in the other. Now, as both
had been simultaneously exposed, it follows to demonstration that,
although both were correctly placed, vertically in relation to that
particular sitter, behind whom the figure appeared, and not so
horizontally, this figure had not only not been impressed on the
plate simultaneously with the two gentlemen forming the group, but
had _not_ been formed by the lens at all, and that, therefore, the
psychic image might be produced _without a camera_. I think this is
a fair deduction. But still the question obtrudes: How came these
figures there? I again assert that the plates were not tampered
with by either myself or any one present. Are they crystallizations
of thought? Have lens and light really nothing to do with their
formation? The whole subject was mysterious enough on the
hypothesis of an invisible spirit--whether a thought projection or
an actual spirit, being really there in the vicinity of the
sitter
