There could be no doubt; it was impossible for any one to enter the cabinet except through the door of the seance-room, in the presence of the whole audience. To be perfectly sure on this point, I sought and obtained permission to sit next the cabinet, which place I occupied for more than forty sittings. I know that it is impossible to use a confederate in this cabinet without its being instantly detected. Having settled this so thoroughly that it could not come up as an element of doubt in any future investigations I might make, the next step seemed to be a plain one.

The forms that came from the cabinet were either personations by the medium, or they were what they purported to be--materializations. I had, during this time, allowed nothing to pass unnoticed. From forty to sixty forms would often manifest at a seance, apparently of both sexes, and of all ages and sizes, from a little child to extreme old age, each form individualized and complete in itself. What claimed to be my wife came to me quite often, and so many times disappeared in the way heretofore described, that I was no longer startled by the occurrence, for I had become so familiar with it that I had come to regard it as a natural consequence of her appearance. She not only grew stronger, but the likeness was much improved, and the resemblance to the medium, at times, entirely disappeared. In my first visits to these seances, I was led, like many others, to attach great importance to the resemblance which these forms might bear to what they claimed to have been when in earth-life. I was constantly looking for it, and have seen many instances where the likeness was so marked that it would have been impossible to mistake it; yet I have learned not to regard it as positive evidence of identity. Whatever they may be, whether from this or the other side of life, there can be no question that they possess the wonderful power of changing their forms at pleasure, as any one at all familiar with them can testify. I have seen a tall young man, wearing a full beard, claiming to be a brother of the lady with me, while standing before her, one hand on her waist, the other in mine--upon her saying, "I have not seen you since you were a lad; how do you suppose I should know you now?"--stoop, kiss her on the cheek, and raise his roguish face without the beard; at the same time diminishing in size until he was more nearly like the boy she knew. I have witnessed similar changes outside of the cabinet, in the presence of the audience, quite often. The mental and moral tone of the audience has more to do with the character of the seance than the medium has. I have, several times, by the action of a strong will, caused the forms to recede from the position which they at first assumed.
