For use mix as follows: for brown-black tones 1 part A, 1 
part B, 1 part C, and 3 parts water. By reducing B, a softer 
developer is obtained; by reducing A, a harder developer is 
obtained. For blue-black tones: mix 1 part A, 1 part B, 1 
part D and 3 parts water. To every 35 oz. of developer, add 
1% to 234 drams of 10 per cent solution of potassium 
bromide.
