Summary of Precautions

• Keep separate the cloths for cleaning the glass, &c.
• Be careful to clean the glass thoroughly.
• Any cloth when once used for cleaning a plate of glass after the application of the hypo-sulphite of soda should be kept for this purpose alone.
• Avoid the too near proximity of diffused light, or that of a candle or lamp, unless it is shaded by a yellow screen of glass.
• Take care that your solutions are put into bottles with lips.
• Clean the stopper and neck of the collodion bottle after each day’s use.
• Avoid disturbing any sediment there may be at the bottom of the iodized collodion bottle; and if there should be much sediment, pour off the clear solution from it into a clean bottle for use.
• Keep separate a cup or measure for the developing solution, as also one for the application of the hypo-sulphite of soda.
• Keep clear all the solutions by filtration.
