DEVELOPMENT 89 
Take 8 oz. each of A, B and C and add water to make one 
gallon (237 ccm to 3785 ccm). Time of development at 
65° F. (18° C.) from 9 to 12 minutes. This developer can 
be repeatedly used if kept up to its normal strength. For 
strengthening use 2 oz. each of A, B and C to each 8 oz. of 
water (59 ccm to 237 ccm).
