are those made by Wing of Boston, by the Amer-
ican Optical Company, of New York, and the
Success Camera boxes, sold by E. & H. T. An-
thony, also of New York. In principle these boxes
are the same, only differing in design or pattern
and in the indicators, and arrangements for mak-
ing the various movements. They are of all sizes
and suited to all varieties of work.
The half plate box, so called, (few are made of
a smaller size), will make with a single tube, one,
two, four, six or sixteen pictures on a quarter
plate by as many moves; with four tubes it will
make, on a quarter plate, four pictures by one
exposure, eight by two exposures, or sixteen
"gems'^ by four exposures. On a half plate
eight pictures by two exposures, thirty-two by
eight exposures—with four tubes. The 5 by 7
Victoria box, with one tube, will make two Vic-
toria portraits by two exposures. One imperial or
cabinet size by one exposure, four cartes-de-visite
by four moves, and with four tubes, sixteen
gems on a quarter plate and thirty-two on a half
plate—with nine tubes, nine, eighteen or thirtysix
on 5 by 7 plate, according to size. The
4-4 or whole plate box is probably most useful,
as it embraces the whole range of sizes, both in
plates from 1-9 to 4-4, and in pictures from one
on 4-4, any size, to sixty-four on 4-4 plate.
There are other boxes made but they are useful
only where vast quantities of pictures are made
at exceedingly low prices, as if you were to make
