Transfer the developed film tothe third tray and rinse two orthree times with water, leaving itto soak while the next film is beingdeveloped. A dozen negatives can be developed oneafter the other in one portion ofdeveloper ; then it should be thrownaway and a fresh portion mixed. Only one negative should be developedat a time until the operator becomesexpert, then he can manage three ortour in the tray at one time and thedeveloper will answer for twenty-fourfilms before being exhausted. As each successive negative is developedit should be put, with the precedingnegatives, in the washing tray andthe water changed twice, to preventthe developer remaining in the filmsfrom staining them. 7. Put two tablespoonfuls of Hypo-sulphite of Soda into the fourthtray, fill two-thirds full of water,and stir until dissolved. This iscalled the fixing bath. 8. Immerse the negatives one by onein the fixing bath until they areentirely clear of white spots and aretransparent instead of milky bytrans
