[6]This method will probably be scoffed at by some enthusiasts, but it should be remembered that the simpler and more audacious methods are the most likely to succeed, just because they are so obvious that no one thinks of them. The sittermustkeep still andmustlook at the camera for some seconds while the exposure is being made, and provided the accomplice is revealed by a carefully silenced mechanism the chances of detection are negligible.

[8]This may have been true, but was certainly not the principal reason that I had to have the plate destroyed! I had over-exposed my spirit, and I feared this plate would not bear closer inspection (I did not sign the minutes of the first three meetings).

[10]Note.—Some believers in spirit photography will dissent from this view on the ground that experiment has shown that when a photograph is taken the extra is not produced by the reflection of ultra-violet light from an “object” (partial materialisation or the like) but by the use of a “psychic transparency” applied to the plate and exposed to “spirit” light. With the first part of this we cordially agree, but the hypothesis of the “psychic transparency” seems to be no more than a resolute attempt to evade the plainest indications of fraud.Vide infra.—[Ed., P.R.Q.]
