t ten minutes--she said to me: 'I think I am going
asleep; I am very tired: I am going to lie down.' And feeling her
way in the darkness, she handed me the plate.

"I then went to develop it, and was surprised to see this
astonishing figure of an eagle. I have called it a
'dream-photograph,' although my wife does not remember having
dreamed of a bird or anything else while she held the plate."

Dr. Baraduc, of Paris, likewise asserted that he had obtained psychic
photographs of human radiations and of human thought. For instance,
calm, peaceful emotions are said to produce pictures of softly
homogeneous light, or the appearance of a gentle shower of snowflakes
against a black background; whereas sad or violent passions suggest, in
the arrangement of the light and shadows, the idea of a whirlpool or
revolving storm, somewhat like a meteorological diagram representing a
cyclone. If these photographs are really what they are believed to be,
they would seem to indicate that, in our ordinary normal condition, we
emit radiations which are regulated and flow forth in smooth, even
succession; but when violent emotions, such as anger or fear, break
through the control of the will and take possession of us, they produce
a violent and confused emission.

There is no reason, _a priori_, why the soul should not be a
space-occupying body, save for the tradition of theology. For all that
we know, the soul might be a point of force, existing within and
animating some sort of ethereal body, which corresponds, in size and
shape, to our material body. But at all events, there is an abundance of
very good testimony to the effect that the shape of the spiritual body
corresponds to that of the material body; and, as such, it certainly
occupies space, and possibly has weight also. It might and it might not;
it is a question of evidence. It will have to be settled, if at all, not
by speculations, but by _facts_. Are there any facts, then, that would
seem to indicate that the soul might be photographed? Have we any
evidence that the soul may be photographed--say, at the moment of death?
If so, we should have advanced a great step in our knowledge of this
subject.

Before I adduce the evidence on this point, however, it may be well to
illustrate the fact that there is no inherent absurdity in the idea, as
many might suppose. Of course the spiritual body would have to be
material enough to reflect light waves, bu
