Among the strong points in evidence of the genuineness of these manifestations are the marked individuality and constant variations that appear. The seances with the same medium will be found to differ widely; no two of them are exactly alike. Sometimes they will be exceedingly good, and at other times almost an entire failure. If they were in any way due to confederates, or to personation by the medium, such variations would not be likely to occur. Again, the seances with one medium differ essentially from those with another; so much so that each medium may be said to have a phase of mediumship distinct in itself. The forms may appear quite different in outward shape, when coming through one medium from what they do in coming through another. The mental characteristics will, however, as I have found, be retained in both instances. This has often led to confusion and distrust with those who visit different seances. The tendency is very strong to give precedence to mere outward appearance, without reference to character. In no case is the old adage, "A little learning is a dangerous thing," more applicable than to the study of this subject. The shallow investigators, the touch-and-go people, will, in most cases, find themselves left in bewilderment and doubt. These things are not to be settled by witnessing one or two seances. Nor is the character of the manifestations, as expressed through any medium, to be determined without considerable experience. From statements, and especially from the impression I received on my first interview with Mrs. Sawyer, I was led to expect much from her seance. My first seance with her was a disappointment, there being nothing except the delightful interview with little Maud, one of the "cabinet spirits,"[C] to attract the attention of any one familiar with these things. It is due her to say, in explanation, that it was her first seance in Boston, and held under unfavorable conditions. [C] This term is applied to spirits who appear to be constant attendants or assistants in the cabinets of mediums for materialization. On the 11th of August, I again visited her seance, in company with Mrs. Fay. The day was very hot, with a close, moist atmosphere, rendering the seance-room very uncomfortable. The only wonder was that, under such conditions, there could have been any manifestations whatever. I was seated on one side of Mrs. Fay, and a friend of hers on the other. This trio, so to speak, drew the fire of the whole seance; the only strong and decided manifestations appearing on that side of the circle. Auntie, Mrs. Fay's control, stood behind us, invisible to all except her medium, occasionally making remarks in her hoarse, unmistakable voice. Coming, as the voice did, out of space, with no organized being in sight to produce it, the effect was at times startling.
