Abstract
THERE is probably no other art that is so encumbered with formulae as photography. Every maker of sensitive material seems to consider it his duty to supply his own particular formulæ for its use, and no doubt this has something to recommend it, but even conveniences may be multiplied until they result in confusion. Many formulae for developers, for example, differ only in the methods of expressing them, except to an inappreciably small extent due to the use of different weights and measures. And when it is borne in mind that by far the greater number of formulæ are not based on a systematic trial of the effects of varying each of its constituents, as all ought to be, the value of even notable differences disappears.
