exsiccate

With this simple introduction I now avow myself the originator and patentee of exsiccated ammonia alum baking powder.

A useful dusting-powder is one consisting of calamine and 5 per cent. salicylic acid; the exsiccated sulphate of iron, in the form of a powder, may be employed in cases which resist this treatment.

Equal parts of boric acid and exsiccated alum serve very well in such cases.

The fresh root, wounded early in the spring, yields and odorous yellow juice, which slowly exsiccated proves an elegant gummy resin, very rich in the virtues of the Angelica.

The use of exsiccated ammonia alum has been declared unhealthful by the advocates of other baking powders, and every manufacturer using it has been held up for public reprobation.
