3738 Developing Dish, patent form, with well or cistern. 



In introducing this article, as shown in the accompanying illustration, a great advantage is offered to the 

 operator, for, as will be seen, the well at the right hand end of the dish is of such a form as to hold sufficient 

 developer to develop about one dozen plates of the particular size (quarter plate, 5 by 4 in., half plate, and whole 

 plate) for which the dish is made. When the operator is ready, the amount of developer is placed in the well, 

 and the plate placed in its position. By tilting the dish the developer is then flooded over the plate, continuing 

 this until the plate is developed. The developer is then allowed to flow into the well, the plate remaining free 

 of the developer, so enabling the operator to take out the plate without staining the fingers as in the old method. 

 Another advantage is that when the operator is not actually developing the plates, there is tess air surface operating 

 on the developer in the well, thus avoiding decomposition.
