Immerse the red picture, before it is dry, in a solution of p212
| Sesqui-chloride of iron | 30 grains. |
| Distilled water | 3 ounces. |
The tone will soon change to green; fix in water, wash and dry before the fire.
PROCESS FOR VIOLET PICTURES.
Float the paper for three or four minutes on a bath of:
| Water | 2 ounces. |
| Nitrate of uranium | 2 drachms. |
| Chloride of gold | 2 grains. |
Afterward take them out and dry. An exposure of ten or fifteen minutes will cause the necessary reduction; the picture has a beautiful violet color consisting of metallic gold. Wash and dry.

The beautiful and sparkling gradation of light and shade, the variety and depth and richness of tone and color inherent in a fine example of this picture, renders it most positively "a thing of beauty and a joy forever,"
