is removed from the second clearing bath and placed in the third, the second print is placed in the second bath, and this leaves the first bath ready for the third print. When three prints have been cleared in the first bath, it is poured away, and the second bath put in its place, the third in the place of the second, the first dish now being in the third place, and filled with fresh clearing solution. The second and third baths, which have now become the first and second, are treated in a similar manner. It is always as well to use a good quantity of developer, as it can be used for two or three prints, or even more, without any loss of detail, if the developer is used for too many prints, however, the latter gradually become lacking in detail or too full of contrast. The used developer need not be thrown away, but placed on one side and regenerated. Having finished our development, the develop-ing dish is washed, dried, and put away. The- prints still in the clearing baths are placed in one dish and flooded twice with fresh clearing solution, the solution being allowed to act for one minute each time, and then well washed for at least half an hour in five or six changes of water, preferably one hour in ten changes of water. The print is then ready for fixing, which may be effected by immersing for ten minutes in

The print should be then taken out, and preferably placed in a second fixing bath of the same strength as the above, where it should remain for ten minutes'. The time required for thorough fixation varies much according to the texture of the paper and the hardness of the film ; but if the sheet is held up to the light the disappearance of the opalescent bromide can generally be traced in the white parts. At least double the time required for the apparent solution of the bromide should be given. For washing the prints any of the usual washing tanks may be utilised, or the prints may be placed in a dish and washed by changing the water every ten minutes for at least two hours.
Drying, mounting, and finishing the prints: To dry the washed prints it is advisable to hang them over a rod or cords. They should not be dried between blotting-paper. We have suc-cessfully used thin laths nailed across a room, on which the prints are laid. Artificial heat should not be used, unless it is warm
