r letters purporting to be written by him. C is
B's clerk, whose duty it was to examine and file B's correspondence. D
is B's broker, to whom B habitually submitted the letters purporting
to be written by A for the purpose of advising with him thereon.

"The opinions of B, C, and D on the question whether the letter is in
the handwriting of A are relevant, though neither B, C, or D ever saw
A write.

"The opinion of E, who saw A write once twenty years ago, is also
relevant."

Article LI I: "Comparisons of a disputed handwriting with any writing
proved to the satisfaction of the judge to be genuine is permitted to
be made by witnesses, and such writings, and the evidence of witnesses
respecting the same, may be submitted to the court and jury as
evidence of the genuineness or otherwise of the writing in dispute.
This paragraph applies to all courts of judicature, criminal or civil,
and to all persons having by law, or by consent of parties, authority
to hear, receive, and examine evidence."
