Melt in twice its weight of boil. ing water and shake well. Pour the melted butter into ice-water, to regain its consistence. Another: Wash in good new milk, in which the butyric acid, which causes the rancidity, is freely Soluble. Wash afterward in cold spring-water. Another plan is to beat up 1/4 lb. good fresh lime in a pail of water. Allow it to stand for an hour, until the impurities have settled. Then pour off the clear portion, and wash the butter in that.
Infuse 3 gills of salt in 4 quarts of water. Put in the calico while the solution is hot, and leave until the latter is cold. It is said that in this way the colors are rendered permanent, and will not fade by subsequent washing.
Wash the floor before laying with spirits of turpentine or benzine. Do not do this with a fire in the room, or with any matches or lights near.
Rancid butter, pork, and lard casks may be purified by burning straw or shavings in them.
This, in cellar timbers, can be prevented by coating the wood with whitewash to which has been added enough copperas to give the mixture a pale-yellow hue.
Provide yourself with a thermometer, a glass tumbler filled with water, and a piece of ice; then notice how low your thermometer, when placed in the tumbler, has to sink before any moisture begins to show itself on the outside of the vessel of cold water. The lower the temperature to which the thermometer has to sink before moisture is precipitated, the less there is of it in the moisture of the cellar.
Turn the chair-bottom upward, and with hot water and a sponge wash the cane; work well, so that it is well soaked; should it be dirty, use soap; let it dry in the air, and it will be as tight and firm as new, provided none of the canes are broken.
Rub over with fine soap, and, while the lather is still on, scrub the hands thoroughly with about a tablespoonful of Indian meal. Rinse with tepid water, dry thoroughly, and wet again with warm water containing a quarter of a teaspoonful of pure glycerine. Dry without wiping, rubbing the hands together until all the water has evaporated. Do this at night before retiring, and the effect will be apparent by morning.
A folded newspaper placed over the chest inside the vest, on going out during raw spring weather, constitutes an excellent protector for the lungs.
(Jently strew the powder upon the surface of cold water. Chicory, burnt sugar, etc., contain no oil, and their caramel is very quickly extracted by the water, with production of a brown color, while the particles themselves rapidly sink to the bottom of the water. On stirring the liquid, coffee becomes tolerably uniformly diffused without sensibly coloring the water, while chicory and other sweet roots quickly give a dark-brown turbid infusion. Roasted cereals do not give so distinct a color.
