calls its "anatomy" or "skeleton." He says that some persons in making
successive strokes, make the turn from one to another sharply angular,
while others make it rounded or looping. Writings produced in both
ways appear the same to the eye, but under a magnifying glass the
difference in the mode of executing is shown. As illustrating that
point, he makes the following statement in respect to a case involving
the genuineness of the alleged signature of an old man whose
handwriting was fine and tremulous:

"On making a magnified copy of the signature, I found that the
tremulous appearance of the letters was due to the fact that they were
made up of a series of dashes, standing at varying angles with each
other, and further, that these strokes, thus enlarged, were precisely
like these constituting the letters in the body of the note, which
were acknowledged to have been written by the alleged forger of the
note. Upon the introduction of this testimony the criminal withdrew
the plea of not guilty and implored the mercy of the court."

As one means of determining whether the whole of a writing was
executed at the same time, and with the same ink, or at different
times, and with different inks, Mr. Peacock further says that the
photographic process is very effective because it not only copies the
forms of letters but takes notice of differences in the color of two
inks which are inappreciable by the eye. He states that:

"Where there is the least particle of yellow present in a color, the
photograph will take notice of the fact by making the picture blacker,
just in proportion as the yellow predominates, so that a very light
yellow will take a deep black. So any shade of green, or blue, or red,
where there is an imperceptible amount of yellow, will pink by the
