KOEPFF & SOEHNE) in 731 mL of distilled water instead of 30 g of type 7598 gelatin in 750 mL of distilled water and in addition contained 18.7 g of a silver bromide-iodide emulsion with 0.7 g of gelatin and 5.03 g of silver bromide-iodide (consisting of 99.7 mol % of silver bromide and 0.3 mol % of silver iodide) with a particle size of 0.05 μm; the quantity of sodium behenate solution added was 358 mL instead of 374 mL; and the addition rate of said sodium behenate solution was 44.1 mL/min instead of 46.6 mL/min. 0.088 moles of sodium behenate were utilized in the reaction, but the quantity of silver nitrate used was not recorded. After the reaction was completed, the free silver ions present were converted into silver bromide by titrating the dispersion with a potassium bromide solution.
