Source text · mention only

Sir Oliver Lodge suggested at the time, among other necessary appliances, a delicate registering balance,--so adjusted that it would record the medium's weight, unknown to her, at all times during the seance--the fluctuations in weight, if any, to be recorded on a revolving drum. Means ought also to be provided for studying the temperature, pulse, muscular exertion, breathing, etc., etc. The lighting of the room should be carefully attended to and capable of the slightest gradation. Means should be provided for obtaining moving pictures of the seance from without the room, unknown to the medium. Were the sittings held in complete darkness, these photographs could be obtained by means of ultra-violet light, with which the room might be flooded.
