1178. These developers must not be used more than once. Development must take place in either total darkness or in the dim light of a special green safe-light. The temperature of the developing solution should be 70° Fahr., and the time of development five minutes.

1179. All the plates must be put into one dish, and the developer flowed evenly over them. Plenty of solution must be employed, or marks may occur on the negative.

1180. Do not clean the backing off the plates until after they are fixed; neither is it necessary to wash the developer off the negatives before fixing; but they must be thoroughly washed, both back and front, afterward.

1181. The best quality negatives are those which would yield a good, though rather flat print on gelatino-chloride printing-out paper.
