If this charge could be reasonably maintained, it would, of course, make all further remarks unnecessary, as our topic would then no longer be one for scientific investigation, but could only be added to the catalogue of fraud. It is possible that there may have been _some_ cases of feigning among the experiments, but these do not affect the general reality of the effects produced. So epilepsy and catalepsy have been feigned; but these diseases are still found real in too many instances. We need not dwell on this point; for it may be safely assumed, that all persons who have had a fair acquaintance with the experiments of electro-biology (so-called), are fully convinced that, in a great number of cases, the effects seen are real and sincere, not simulated. The question then remains: Are these effects fairly attributed to 'electric' influence, or may they not be truly explained by some other cause? Before we proceed to consider this question, it will be well to give some examples of the phenomena to which our remarks apply. We shall state only such cases as we have seen and carefully examined. A. is a young man well known by a great number of the spectators--unsuspected of falsehood--knows nothing of the experimenter or of electro-biology, not even the meaning of the words. After submitting to the process employed by the lecturer--sitting still, and gazing fixedly upon a small disk of metal for about a quarter of an hour--he is selected as a suitable subject. When told by the experimenter that he cannot open his eyes, he seems to make an effort, but does not open them until he is assured that he can do so. He places his hand upon a table--is told that he cannot take the hand off the table--seems to make a strong effort to remove it, but fails, until it is liberated by a word from the lecturer. A walking-stick is now placed in his right hand, and he is challenged to strike the extended hand of the lecturer. He throws back the stick over his shoulder, and seems to have a very good will to strike, but cannot bring the stick down upon the hand. He afterwards declares to all who question him, that he 'tried with all his might' to strike the hand. A. has certainly no theatrical talents; but his looks and gestures, when he is made to believe that he is exposed to a terrific storm, convey a very natural expression of terror. He regards the imaginary flashes of lightning with an aspect of dismay, which, if simulated, would be a very good specimen of acting. In many other experiments performed upon him, the effects seem to be such as are quite beyond the reach of any scepticism with regard to his sincerity. He cannot pronounce his own name--does not know, or at least cannot _tell_, the name of the town in which he lives--cannot recognise one face in the room where scores of people, who know him very well, are now laughing at him. On the other side, we must state, that when a glass of water
