mother-liquor

After about thirty hours a reddish powder deposits, from which ellagic acid may be extracted with pyridine; the mother-liquor on being concentrated yields luteic acid.

These were separated, and the mother-liquor on standing deposited some oblong rectangular crystals.

An apparatus with a copper basket four inches in diameter has been found extremely useful in the laboratory for drying such substances as granulated sulphate of copper and sulphate of iron and ammonia, but more especially for drying sugar, which when crystallized in very small crystals cannot be readily separated from the sirupy mother-liquor by any of the usual laboratory appliances.

But at length a point is reached at which the temperature ceases to fall until the whole of the remaining mother-liquor has solidified, with the production of a compound called

The salt so separating may be either anhydrous or a "hydrate" of greater concentration than the mother-liquor.

They seek to find, as it were, the mother-liquor of the great ocean, so as to express the truth in a crystal.

-- This element was discovered in 1826 by M. Balard, in the mother-liquor, or residue of the evaporation of sea-water.

-- The mother-liquor containing bromides is treated with a current of chlorine gas, which decomposes these salts, setting the bromine free, which at once colors the liquid to a reddish brown color.

All the soft solid parts of the frame may be considered as ever temporary precipitates or crystallisations (to use the word but loosely) from the blood, that mother-liquor of the whole body; always being precipitated or suffered to become solid, and always being redissolved, the forms remaining, but the matter never the same for more than a moment, so that the flesh is only a vanishing solid, as fluent as the blood itself.

Thus, in the operations of filling the various boiling pans with water or mother-liquor; the transference of the boiling solution of saltpetre to the draining trough, and thence to the crystallizing machines; the cooling down of the solutions, and their constant agitation to break up the forming crystals into fine particles, and transferring of these to an adjoining tank; the washing of the crystallized mass, and the subsequent removal of the mother-liquor and wash-waters, were all accomplished by machinery, with the assistance of two or three workmen only.
