The process here given comprehends a double formula, and to insure satisfactory results, the directions subjoined should be carefully followed.
No. 1.
| Nitrate of Silver | 3 | drachms |
| Stronger Water of Ammonia | ½ | ounce |
| Distilled or Rain Water | ½ | ounce |
No 2.
| Pyrogallic Acid | 3 | drachms |
| Alcohol | ½ | ounce |
| Distilled or Rain Water | 6 | ounces |
Directions.—Formula No. 1, and formula No. 2, should each be put up in a separate bottle.
In compounding, each of the first two ingredients should be combined and reduced to a solution and the water then added.
Before using these preparations the beard or hair should first be thoroughly washed and dried.
Then apply No. 1 with the fingers, and when partly dried apply No. 2 with a tooth brush and a comb, being careful to get the dye down to the skin. If convenient let the party go out into the open air for an hour. Otherwise the hair should be thoroughly dried with a fan, and washed with soap and soft water. This formula was brought from Germany by a St. Louis barber and sold to the author in 1869. Properly put up it is not only first-class, but I have never found any other preparation equal to it.
