es. On
another occasion the board was depressed, and showed a pressure of 100
grammes, which lasted for 35 seconds. On other occasions lesser
depressions were noted, but for longer periods of time. On several
occasions the balance registered a downward pressure for two minutes or
more. This was in good light, and was carefully observed by two
physicians, as well as by Professor Alrutz. The "subjects" were, in this
case, ladies of good Swedish families, who had never seen or heard of
the instrument before. They were, however, during the experiments,
treated as professional "mediums," and every precaution was taken to
prevent fraud. The following were some of the precautions observed:

The light was sufficiently good to enable the observers to _see_ that no
threads or hairs were attached to the board or any part of the apparatus
or balance. They also ascertained this with their hands. It was also
seen that none of the subjects lifted the board by slipping their
fingers under the edges of the board and pulling it upwards. (It may be
remarked in this connection that even had they done so this would not
account for the results noted; since, in several instances, the downward
pressure recorded was more than the weight of the entire board.) As the
eyes of the observers were close to the board and to the fingers of the
subjects, it was clearly seen, however, that nothing of the sort took
place. Besides, as before said, the subjects who tried the board were
ladies, and not professional "psychics" in any sense of the word.

It was also ascertained that no sticky material was upon the fingers of
the subjects; they were carefully examined both before and after each
experiment. Further, to test this hypothesis fully, thin strips of wood
(shavings) were on several occasions introduced between the subjects'
fingers and the board, which was depressed. Had they lifted their
fingers, therefore, they could not possibly have lifted the board, which
would not have adhered to them under these circumstances.

_3rd Series._--Two "functionaries of state" attended this series, the
principal subject tried being the wife of one of these dignitaries. He
himself was extremely sceptical of his wife's ability to move the board,
and remained so until convinced by the facts! The board was lowered, and
the balance showed a pressure of from 70 to 100 grammes. The subject was
extremely fatigued after these tests, and went to sleep almost
immediately. Oth
