kind enough to secure, if possible, the statements of any additional
witnesses who might have been present on this occasion, and he sent me,
in response to this request, the following affidavit, signed by five of
the witnesses who were present at the time:

California Psychical Research Society,
San Francisco, Calif., Nov. 3, 1920.
Dr. Hereward Carrington.
504 West 111th St.
New York City.

Dear Dr. Carrington.

Enclosed is the print I promised you of the "Thought Photograph"
taken by a Committee composed in part of members of the Council of
the California Psychical Research Society, in May, 1919. The
conditions were as follows: I purchased at Hirsch & Kaye, opticians
and photo-supplies, a box of one dozen ordinary rapid Seed plates.
I took the box unopened to the Committee meeting, which was held
at the X-Ray Laboratory of Preston & Huppert in this city. Mr.
Henry Huppert, Dr. Frank Collins, Dr. Cecil Nixon and myself went
into the dark room, where Mr. Huppert opened the box of plates,
took one at random from the centre of the package, enclosed it
inside an opaque black envelope, and this again inside another
yellow envelope and sealed it. This was taken outside and suspended
about 12 inches in front of our subject, who was seated and had
previously written down what he would concentrate upon, and handed
the memo to Dr. Collins. The subject drew a rough outline of the
object of his concentration, gazed fixedly upon it for about 5
minutes, then put it aside and for ten minutes concentrated upon
the plate without touching the same. The plate was immediately
taken into the dark room and developed, and the image of the cross
developed at once, clear and strong. One of the Committee was in
the room with the subject during the whole time, and there was no
opportunity for any tampering with the plate. The object developed
proved to be the one previously written down and handed to Dr.
Collins.

Yours very truly,

Vincent Jones,
Frank T. Collins, D.O.,
J. C. Anthony, M.D.,
Cecil E. Nixon, D.O.S.,
Henry K. Huppert.
