Rappings on the walls and floor are also too common to mention, but should be classed in the category of telekinetic energy.
THEORY OF ECTOPLASM
One of the investigators has advanced the theory of ectoplasm, which is a formless stuff emanating from the body of the medium. I have no doubt but this theory is correct as far as it goes; but am not willing to advance it as being sufficient to explain all the phenomena. For instance, according to this theory, if any one stands in front of the medium the emanation is blocked and no results will follow. I have sat in a room and had a glass of water brought from another room and held to my lips while I drank it. It was a real glass and real water and I was really there, and in a perfectly normal state of mind. I could not possibly account for the above-stated incident on the theory of ectoplasm; but I could account for it through the theory of mental power.
The theory of ectoplasm certainly will not account for levitation, where the body of the medium is lifted from a chair and carried to some other place in the room. This can be accounted for only on the theory that there is a power that transcends the better-known physical laws. Experience has taught that there are many things in life that cannot be
