or general
use. This comes in five different weights: _A_, a thin paper with smooth
surface, useful where detail is desirable; _B_, a heavier paper with
smooth surface, for large prints or for illustration purposes; and _C_, a
still heavier paper with a rough surface for broad effects and prints of
large size. _BB_, heavy smooth double weight; _CC_, heavy, rough, double
weight. Each of these varieties may be had in two grades, according to the
negative in hand or the effect desired in the print, viz.: _hard_, for use
with soft negatives where we desire to get vigor or contrast in the print,
and _soft_, for use with hard negatives where softness of effect is
desired in the print. For general use the _soft_ grade is preferable,
although it is advisable to have a supply of the _hard_ paper at hand as
useful in certain classes of work. The tones obtainable on the _Standard_
paper range to pure black, and are acceptable for ordinary purposes. For
pictorial work or special effects other papers are preferable.

_Platino-Bromide_ paper gives delicate platinotype tones, and where
negative, paper and manipulation are in harmony, the prints obtained on
this paper will be indistinguishable from good platinotypes in quality and
attractiveness. This paper comes in two weights, _Platino A_, a thin paper
suitable for small prints, and having a smooth surface useful for
detail-giving; and _Platino B_, a heavy paper with rough surface,
peculiarly suited for large contact prints or enlargements. Both varieties
are obtainable in _hard_ or _soft_ grades, characterized as above. _Matte
Enamel_, medium weight; _Enameled_, medium weight; _Velvet_, medium
weight.

_Royal Bromide_ is a capital paper in its proper place, _i.e._, for prints
not smaller than 8 x 10 inches, and then only when breadth of effect is
desired in the picture. It is a very heavy cream-colored paper, rough in
texture, and giving black tones by development, but designed to give sepia
or brown tones on a tinted ground by subsequent toning with a bath of hypo
and alum. This paper, also, may be had in two grades for _hard_ or _soft_
effects; it is further adapted for being printed on through silk or
bolting cloth, this modification adding to the effect of breadth
ordinarily given by the paper itself. I have seen prints on this paper
which were altogether pleasing, but subject and negative should be
carefully considered in its use. Rough Buff papers are very similar in
