PREFACE. Al alertness on the part of the observer than that which is fixed and permanent. Mr. Turvey’s own account of the way in which he exercises his abnormal mentality is very interesting, and sometimes illuminating. Take for instance his description of how he sometimes sees his visions of things to come, He says “ At certain times I see a sort of film or ribbon continually moving, as does an endless belt in a cinematograph film. This film is in colour of a very, very pale pinky-heliotrope, and it seems to vibrate with very great velocity. Upon it are numerous little pictures, some of which appear to be engraved on the film itself, whilst others are like pale blue photographs stuck on to the film. The former I have found to refer to past events, the latter to those about to happen. The locality of the event is judged by the scenery and the climatic heat. I have to estimate dates by the clearness of the pictures.” Again he says: “I foresee more unpleasant than pleasant things. I believe the reason to be that evil, being nearer to matter than to spirit, is more ponderous in the ether than its opposite, and is therefore sensed more easily by a Seer, I not only see, but feel, the density of evil.”
