"Ah, so I thought," said Hewitt, catching the book as it fell. "But don't lose this place in the encyclopædia. Read the name of the article. What is it?" Mr. Crellan looked absent-mindedly at the title, holding the will before him all the time. Then, mechanically, he read aloud the word, "_Hypnotism_." "Hypnotism it is," Hewitt answered. "A dangerous and terrible power in the hands of an unscrupulous man." "But--but how? I don't understand it. This--this is the real will, I suppose?" "Look at it; you know best." Mr. Crellan looked. "Yes," he said, "this certainly is the will. But where did it come from? It hasn't been in this book all the time, has it?" "No. Didn't I tell you I put it there myself as a marker? But come, you'll understand my explanation better if I first read you a few lines from this article. See here now:-- 'Although hypnotism has power for good when properly used by medical men, it is an exceedingly dangerous weapon in the hands of the unskilful or unscrupulous. Crimes have been committed by persons who have been hypnotised. Just as a person when hypnotised is rendered extremely impressionable, and therefore capable of receiving beneficial suggestions, so he is nearly as liable to receive suggestions for evil; and it is quite possible for an hypnotic subject, while under hypnotic influence, to be impressed with the belief that he is to commit some act after the influence is removed, and that act he is safe to commit, acting at the time as an automaton. Suggestions may be thus made of which the subject, in his subsequent uninfluenced moments, has no idea, but which he will proceed to carry out automatically at the time appointed. In the case of a complete state of hypnotism the subject has subsequently no recollection whatever of what has happened. Persons whose will or nerve power has been weakened by fear or other similar causes can be hypnotised without consent on their part.'" "There now, what do you make of that?" "Why, do you mean that Miss Garth has been hypnotised by--by--Cranley Mellis?"
