In examining and reporting these cases the witnesses averred that certain people, whom they called “materializing mediums,” had the strange physical gift that they could put forth from their bodies a viscous, gelatinous substance which appeared to differ from every known form of matter in that it could solidify and be used for material purposes, and yet could be reabsorbed, leaving absolutely no trace even upon the clothes which it had traversed in leaving the body.

This substance was actually touched by some enterprising investigators, who reported that it was elastic and appeared to be sensitive, as though it was really an organic extrusion from the medium's body.
