The next year followed a paper on "A New Method of Calculating the Times of Development at Various Temperatures," which was the foundation of the system of time and temperature development now so widely known and used. Kodak, Limited, were the first to take it up, and other manufacturers followed in due course. Among his many inventions for the measurement of photographic densities, the F.R.B. photometer is now used by Ilford, Limited, a she standard instrument.
