For large plates and prints it is not only necessary to use larger dishes, but also more liquid, both =Anthion solution= and water. An excess of =Anthion= or of water is decidedly useful, but less is disadvantageous.
The above directions for washing relate to those who have no continual flow of water at hand.
If a continual flow of water is obtainable, it is advisable to wash the plates or prints in flowing water for a quarter of an hour, and then dip in the =Anthion solution= and test the result as above.
