As it appeared to your Committee to be of the greatest importance that they should investigate the phenomena in question by personal experiment and test, they resolved themselves into sub-committees as the best means of doing so. Six Sub-committees were accordingly formed. These reports, hereto subjoined, substantially corroborate each other, and would appear to establish the following propositions:-- 1. That sounds of a varied character, apparently proceeding from articles of furniture, the floor and walls of the room (the vibrations accompanying which sounds are often distinctly perceptible to the touch) occur, without being produced by muscular action or mechanical contrivance. 2. That movements of heavy bodies take place without mechanical contrivance of any kind or adequate exertion of muscular force by the persons present, and frequently without contact or connection with any person. 3. That these sounds and movements often occur at the times and in the manner asked for by persons present, and, by means of a simple code of signals, answer questions and spell out coherent communications. 4. That the answers and communications thus obtained are, for the most part, of a commonplace character; but facts are sometimes correctly given which are only known to one of the persons present. 5. That the circumstances under which the phenomena occur are variable, the most prominent fact being that the presence of certain persons seem necessary to their occurrence, and that of others generally adverse. But this difference does not appear to depend upon any belief or disbelief concerning the phenomena. 6. That, nevertheless, the occurrence of the phenomena is not insured by the presence or absence of such persons respectively. The oral and written evidence received by your Committee not only testifies to phenomena of the same nature as those witnessed by the sub-committees, but to others of a more varied and extraordinary character. This evidence may be briefly summarized as follows:-- 1. Thirteen witnesses state that they have seen heavy bodies--in some instances men--rise slowly in the air and remain there for some time without visible or tangible support. 2. Fourteen witnesses testify to having seen hands or figures, not appertaining to any human being, but life-like in appearance and mobility, which they have sometimes touched or even grasped, and which they are therefore convinced were not the result of imposture or illusion. 3. Five witnesses state that they have been touched, by some invisible agency, on various parts of the body, and often where requested, when the hands of all present were visible. 4. Thirteen witnesses declare that they have heard musical pieces well played upon instruments not manipulated by any ascertainable agency.
