GENERAL REMARKS.

WELLINGTON Roll Films are the result of many years
of careful experimenting, the object being to make a
film as perfect and as rapid as possible. The film is
transparent, without joins in the raw material, and is coated with
an emulsion of high speed and perfect quality.
In all cases it will be found advisable to develop roll films in
the length ; a flat dish or a developing tank can be used with equal
success. The rolls can easily be handled in 12-exposure lengths
up to 5x4 size. In the larger sizes they may be cut off at the six
exposures and developed half at a time. All roll films are sent
out in such form that they can be used in a developing machine
if this method is preferred.
If it is desired to develop each exposure separately the film
and the black paper should be taken out exactly together, and cut
at the cutting marks on the black paper. That is to say, when
the black paper has been unwound until the film appears, film and
paper should be kept together by holding them firmly, running
