_Aqua Aluminosa Bateana._ P. L. 1745.
This is a compound solution of _alum_ and _sulphate of zinc_; a
fluid-ounce containing about seven grains of each ingredient, it is
powerfully astringent, and is successfully used as a detergent lotion to
old ulcers; as a collyrium, or as an injection in gleet and fluor albus;
it will also often answer in removing chilblains, and in curing slight
excoriations.
