Introduction.
## Abstract Nucleation and crystal growth processes involved in the batch precipitation of photographic emulsions by the addition of silver nitrate to an aqueous solution of bromide and gelatin have been reasonably successfully modeled. Simulation predicts the known increase in average crystal size
Recent attempts within this laboratory to demoiistratc by radioautography the specific localization of low concentrations of i.adioisotopes in rat tissues have emphasized the danger of liistochemical fogging of photographic emulsion. Boyd and Board ( '49) called attention to this phenomenon, and mor
