In the opinion of the leading members of this society, some of the physical phenomena which have been adduced as among those proclaimed to have occurred, such as "apports," scent, movement of objects, passage of matter through matter, bear a perilous resemblance to conjuring tricks, of a kind fairly well known; which tricks if well done can be very deceptive. Hence extreme caution is necessary, and full control must be allowed to the observers--a thing which conjurers never really allow. Sir Oliver Lodge says that he has never seen a silent and genuinely controlled conjurer; and in so far as mediums find it necessary to insist on their own conditions, so far they must be content to be treated as conjurers. For instance, no self-registering thermometer has ever recorded the "intense cold" felt at a _séance_. Flowers and fruit have made their appearance in closed rooms, but no arsenic has penetrated the walls of the hermetically sealed tube. Various investigators have smelt, seen, and handled curious objects, but no trace has been preserved. We have to depend on the recollection of the observer's passing glimpse of spirit lights, of the hearing of the rustle of spirit garments, the touch, in the dark, of unknown bodies. Exquisite scents, strange draperies, human forms have appeared seemingly out of nothing, and have returned whence they came unrecorded by photography, unweighed, unanalysed. Briefly, then, the result of my carefully formed judgment is that a large part of the physical phenomena heard, seen, felt at the average spiritualistic _séance_ must be placed on a level with ordinary conjuring. To return to the recent case of Eusapia Paladino. A number of English scientists, interested in the reports of her _séances_, induced her to come to England and repeat them at Cambridge. Every effort was made to make the experiments as satisfactory as possible. They used netting for confining the medium or separating her from objects which they hoped would move without contact; different ways of tying her were tried; also sufficient light was used in the _séance_ room. She refused to submit to any of these conditions. The investigators pressed her at each sitting to allow some light in the room, and they long persevered in making the control in every case as complete as she would allow it to be. She permitted a very faint light usually at the beginning, but before long she insisted on complete darkness, and until the lights were extinguished the touches were never felt. The sitters then held the medium, the only method of control allowed, as firmly and continuously as possible. This she resisted, and then every form of persuasion was used, short of physical force, to induce her to submit. But she was allowed to take her own way without remonstrance when the sitters were convinced of the constant fraud practised.
