The following are tried and useful formulas:

I

Sulphite (not sulphate) of lime, in fine powder, 1 part; marble dust, ground oyster shells, or chalk, 7 parts; mix, and pack tight, so as to exclude the air.

II

Sulphite (not sulphate) of potassa, 1 part; new black-mustard seed (ground in a pepper mill), 7 parts; mix, and pack so as to exclude air and moisture perfectly. Dose (of either), 0.5 ounce to 1.5 ounces per hogshead.

III

Mustard seed, 14 pounds; cloves and capsicum, of each, 1.25 pounds; mix, and grind them to powder in a pep-

per mill. Dose, 0.25 to 0.5 pound per hogsead. A portion of any one of these compounds added to cider, or the like, soon allays fermentation, when excessive, or when it has been renewed. The first formula is preferred when there is a tendency to acidity. The second and third may be advantageously used for wine and beer, as well as for cider. The third compound greatly improves the flavor and the apparent strength of the liquor, and also improves its keeping qualities.
