has been made towards simplification and economy. No useful
purpose is served by an array of imposing-looking bottles—
often filled with oxidized solutions—on the dark-room shelves.
Pyro is obviously suitable for plate development only, but if metol-
hydrokinone is used there is no reason whatever why the same
developer should not serve alike for plates and papers. The metol-
hydrokinone formula given in this book is the same for plates,
films, Lantern plates, S.C.P. Lantern plates, S.C.P. and bromide
paper. It can also be used for B.B. paper, although a better result
will be obtained with the special formula recommended. It
will be noted that in certain cases the stock solution has to be
diluted with an equal volume of water.
The Borax-M.Q. formula is also capable of almost universal
application, and for this reason the stock solution should be pre-
pared without bromide, the quantity of this salt required in certain
cases being added from a 10% solution.
