Mr. DEBENHAM quite agreed with Mr. Bridge as to Mr. Glendinning’s _bonâ fides_ in the matter. He would propose, if possible, a committee be formed to be present at some similar séance. A MEMBER stated that Mr. Taylor’s experiments had been vitiated to some extent by his not having the whole of the conditions under his own control (a remark to which Mr. Taylor does not seem to have thought it necessary to reply, as he had already distinctly stated that the _whole_ of the conditions were subject to his entire control). Professor A. HADDON observed that if spirits gave out ultra-violet rays, it would be advisable to use lenses made of quartz, as they would have a far better way of rendering such subjects on the plate than with ordinary lenses, which cut off ultra-violet. Again, had different eyes different powers as regards the taking in and cutting out of different rays? Mr. Friese Greene had shown how it was possible to allow an impression to be made on the retina, and then to be transferred to a plate. Most probably only certain people possessed this power, for it was curious no one had repeated the experiment with success. Mr. T. SHORTER said he had had some experience of the subject, and in many instances such portraits had been distinctly recognised as those of relatives and friends, and it was not by any means a peculiar experience. The late Mr. Beattie, of Clifton, obtained portraits of this kind through Mr. Hudson, to whom he went in a very sceptical spirit. Hudson allowed him to go through all the manipulations himself; Mr. Beattie took his own plates, and inverted them before they were exposed. On one picture, after it was taken he recognised the portrait of his own brother. He (Mr. Shorter) knew of a good many instances of a similar kind. For instance, he said, Dr. Alfred Russel Wallace had had no hesitation in recognising portraits so obtained. Of course there were many taken in this way that could not be identified; but, on the other hand, there were many that could. He could quote forty instances where people could identify them. A MEMBER explained how a collection of portraits of deceased persons can be made by professional photographers. He stated his firm sometimes receive such portraits to copy, and at times when they deliver the copies they pretend that the original pictures are lost or injured; so the customers have nothing to compare the copies with. This brought forth the rebuke from Mr. Maltby (a visitor) that the conduct of the firm might be “smart,” but could not be considered honest.
