least so they thought, able to explain the phenomenon. I shall narrate
the event and also tell the reader what explanation was given, and let
him draw his own conclusions.

This was what happened.

* * * * *

A friend of mine, a clerk in the same office as myself, was an amateur
photographer; let us call him Jones.

Jones had a half plate Sanderson camera with a Ross lens and a Thornton
Picard behind lens shutter, with pneumatic release. The plate in
question was a Wrattens ordinary, developed with Ilford Pyro Soda
developer prepared at home. All these particulars I give for the benefit
of the more technical reader.

Mr. Smith, another clerk in our office, invited Mr. Jones to take a
likeness of his wife and sister-in-law.

This sister-in-law was the wife of Mr. Smith's elder brother, who was
also a Government servant, then on leave. The idea of the photograph was
of the sister-in-law.

Jones was a keen photographer himself. He had photographed every body in
the office including the peons and sweepers, and had even supplied every
sitter of his with copies of his handiwork. So he most willingly
consented, and anxiously waited for the Sunday on which the photograph
was to be taken.
