It is admitted that the possessed sometimes display an eloquence which they are incapable of in their normal condition.[4] In China, possessed women, who never composed a line of poetry in their normal lives, utter their thoughts in verse, and are said to give evidence of clairvoyant powers.[5] The book--_Demon Possession in China_--of Dr. Nevius, for forty years a missionary, was violently attacked by the medical journals of his native country, the United States. The doctor had the audacity to declare that he could find no better explanation of the phenomena than the theory of the Apostles--namely, that the patients were possessed. Not having the fear of man before his eyes, he also remarked that the current scientific explanations had the fault of not explaining anything. For example, 'Mr. Tylor intimates that all cases of supposed demoniacal possession are identical with hysteria, delirium, and mania, and suchlike bodily and mental derangements.' Dr. Nevius, however, gave what he conceived to be the notes of possession, and, in his diagnosis, distinguished them from hysteria (whatever that may mean), delirium, and mania. Nor can it honestly be denied that, if the special notes of possession actually exist, they do mark quite a distinct species of mental affection. Dr. Nevius then observed that, according to Mr. Tylor, 'scientific physicians now explain the facts on a different principle,' but, says Dr. Nevius, 'we search in vain to discover what this principle is.'[6] Dr. Nevius, who had the courage of his opinions, then consulted a work styled 'Nervous Derangement,' by Dr. Hammond, a Professor in the Medical School of the University of New York.[7] He found this scientific physician admitting that we know very little about the matter. He knew, what is very gratifying, that 'mind is the result of nervous action,' and that so-called 'possession' is the result of 'material derangements of the organs or functions of the system.'
