    use, neutralize it carefully with ammonia, and use the liquid by dipping paper in it. St/ruj) of Violets. On 4 oz. of fresh petals of violets pour half a pint of water at- 104° Fahrenheit, stir them together, and in a minute or two strain oil'the water with gentle pressure, and pour 8 oz. of boiling distilled water on the flowers. In 12 hours, strain through linen, let the infusion settle, and decant, then dissolve in it tw ice its weight of refined sugar, by a gentle heat. [A delicate test for acids and alkalies.] Dr. Clark’s Test for Hardness of Water. Dissolve 1 oz. of Hawes’s best white soap in a gallon of proof spirit. It not of such strength that it requires 32 measures to be added to 100 measures of solution of chloride of calcium of 16 degrees of hardness (see below) before it lathers, it must be adjusted to that strength. [The chloride of cal- cium solution is thus made.—Dissolve 16 gr. of pure car- bonate of lime in a small quantity of pure hydrochloric acid, avoiding loss from effervescence; evaporate the so- Ilution to dryness, and dissolve the residue in water, and again evaporate till a neutral solution is obtained; then dissolve in a gallon of water. This forms the standard s uution of 16 degrees of hardness. One measure of this solution with 15 of distilled water constitutes a solution t of one degree of hardness; and so on up to 16 degrees. The degree of hardness expresses the number of grains of carbonate of lime per gallon contained in the water. For the mode of using this test, see Dr. Clark’s pamphlet, or , Parnell’s Chemical Analysis.] Solution of Carbonate of Ammonia. Mr. Parnell directs this test to be prepared by dissolving 1 piart of sublimed carbonate of ammonia in 3 of water, and adding 1 part of water of ammonia. Solution of Oxalate of Ammonia. Dissolve 1 oz. of crystallized oxalate of ammonia in a pint of water. Solution of Sulphuretted Hydrogen. Pass sulphu- retted hydrogen gas (see Gases, page 360) through cold d-stilled water, which has been recently boiled, till it will absorb no more. Keep it in small bottles securelv closed. Solution of Hydrosulphuret of Ammonia. Pass sul-
