SIR KNIGHT E. D. BALL, Spartansburg, S. C., sends a print, and wishes to know what is the reason of the yellowish-brown color. The trouble is in the toning-bath. Test it with blue litmus-paper. If it turns the litmus-paper red, add enough bicarbonate of soda, a little at a time, until it turns the red color back to blue. Use the bicarbonate of soda in solution.
