(1.) Print-on the fat reserve; (2.) dip a pale blue, and dry; (3.)

The property which nitric acid possesses of staining animal matters
yellow, such as the skin, wool, and silk, is here applied to a very

_Of the bronze or solitaire style by mandarining._--The mandarining
mixture, is
1 gallon of nitric acid, of 1·17 spec. grav.; mixed with 3 pints of
solution of nitrate of iron, of spec. grav. 1·65. If the quantity of
nitrate of iron be increased, a darker tint will be obtained. The
temperature of the mixture should be 94° F. The pieces, after
mandarining, are let fall into water, and steeped for an hour.
In order to raise the bronze, and clear away the fat resist, the goods
must be boiled in a bath of soap and soda, as described for orange.
