loor with their chairs, in full
daylight, under (to me) most satisfactory conditions; for I was kneeling
and keeping close watch upon the feet of the chair, and observing that
no one might touch them."

Among other strange manifestations, he positively declares that his
library-bell was brought into a room in which he was sitting with the
medium, with locked doors, both he and his children having seen and
handled the bell a short time before in the library. Also a piece of
China grass was taken from a vase on the table, and before his eyes
seemed to pass through the substance of the table. Observation showed
that there was a crack in the table through which it had apparently
passed. But this crack was much narrower than the diameter of the grass,
yet the latter showed no signs of abrasion or change of shape.

As to the intelligence manifested by this strange power he gives the
following instance. A lady was writing with a planchette. "I asked, 'Can
you see the contents of this room?' 'Yes,' wrote the planchette. 'Can
you see to read this newspaper?' said I, putting my finger on a copy of
the 'Times' which was on the table behind me, but without looking at it.
'Yes,' was the reply of the planchette. 'Well,' I said, 'if you can see
that, write the word that is now covered by my finger, and I will
believe you.' The planchette commenced to move. Slowly and with great
difficulty the word 'however' was written out. I turned round, and saw
that the word 'however' was covered by the tip of my finger. I had
purposely avoided looking at the newspaper when I tried this experiment,
and it was impossible for the lady, had she tried, to have seen any of
the printed words, for she was sitting at one table, and the paper was
on another table behind, my body intervening."

The most remarkable phenomena attested by Professor Crooks, however, are
those classed as luminous appearances, and particularly as luminous
hands. Some of the most striking of those may be here quoted:

"Under the strictest test-conditions I have seen a self-luminous body,
the size and nearly the shape of a turkey's egg, float noiselessly about
the room, at one time higher than any one present could reach standing
on tiptoe, and then gently descend to the floor. It was visible more
than ten minutes, and before it faded away struck the table three times
with a sound like that of a hard, solid body. During this time the
medium was lying back, apparently insensible,
