"Scientific American Supplement, No. 623, December 10, 1887"

This result, we
believe, is unrivaled, and makes this vessel equal in turning
capabilities to many recent warships not much more than half her

FILM NEGATIVES.[1]
[Footnote 1: A communication to the Birmingham Photographic
Society.]

Having had a certain measure of success with Eastman stripping films,
I have been requested by your council to give a paper this evening
dealing with the subject, and particularly with the method of working
which my experience has found most successful. In according to their
request, I feel I have imposed upon myself a somewhat difficult task.
There is, undoubtedly, a strong prejudice in the minds of most
photographers, both amateur and professional, against a negative in
which paper is used as a permanent support, on account of the
inseparable "grain" and lack of brilliancy in the resulting prints;
and the idea of the paper being used only as a temporary support does
not seem to convey to their mind a correct impression of the true
position of the matter.
It may be as well before entering into the technical details of the
manipulation to consider briefly the advantages to be derived--which
will be better appreciated after an actual trial.
