It is only necessary to add that the mechanical movements here described are not among those which, on page 218, I referred to as physically unable to be done by muscular effort on the part of anyone whose hands are only on the table top. I am not in this book describing any cases of that sort. Whatever was the cause of the above mechanical trick movements, which were repeated on a subsequent occasion for my observation, the circumstances were not strictly evidential. I ought to say, however, that most certainly I am sure that no conscious effort was employed by anyone present.

WARNING
It may be well to give a word of warning to those who find that they possess any unusual power in the psychic direction, and to counsel regulated moderation in its use. Every power can be abused, and even the simple faculty of automatic writing can with the best intentions be misapplied. Self-control is more important than any other form of control, and whoever possesses the power of receiving communications in any form should see to it that he remains master of the situation. To give up your own judgement and depend solely on adventitious aid is a grave blunder, and may in the long run have disastrous consequences. Moderation and common sense are required in those who try to utilise powers which neither they nor any fully understand, and a dominating occupation in mundane affairs is a wholesome safeguard.
