bS saying that the first wash had removed all
the INK that was not iron. and that the fumes
OF the sulphuretted hydrogen and ammonia
had merely developed tho iron.
Except India ink. he knew OF no ink that was
no other that could he obliteraled without do.
stroylne the paper. and leaving some trace hat
might have developed with tho other sciences.
and such an ink might have been discoyered.
but Prof. Doremus did not think 30. As Gratis
desk was opposite Mr.. Parker's desk. it was
fair to presume that tho same Ink was used
originally. It certainly was in the check given
TO him for experiment, and, In his opinion. no
change had been m ade In the body OF the check
since 1t was signed.
Prof Doremus explained that q photograph
would show Irregularities not disoernible by
tho naked eye. He had. therefore; photo:
original size but had failed to distinguish any
Inaccuracies. The negatives, and tho checks
that lapse OF time would not interfere with the
power OF the aoid. q check was mashed clean
before the court adjourned. When it sh I'll
