The alimentary tract is relieved of the irritating material by giving the animal a physic of castor or linseed oil. The dose varies from one-quarter to one-half ounce for the lamb and from one to four ounces for the colt or calf. It is advisable in most cases to follow this with the following mixture: bicarbonate of soda one ounce, bismuth subnitrate one-half ounce, and salol one-quarter ounce.

Bitter or saline tonics should be administered in the feed when necessary. The following formula is useful as a digestive tonic: Sodium bicarbonate and sodium sulfate, one pound of each, powdered gentian one-half pound, and oil meal five pounds. A small handful of this mixture may be given with the feed two or three times daily.

Bicarbonate of soda is one of these acid salts, but so feeble is carbonic acid in its acid properties and practical evidences, that we shall see both monocarbonate or "neutral" carbonate of soda and bicarbonate or "acid" carbonate of soda show evidences of, or, as chemists say, react with alkalinity towards litmus.

The caustic alkali may also be determined by first using phenolphthalein as an indicator, which will show by its change from pink to colorless the point at which the caustic alkali has been neutralized and the carbonate has been converted to bicarbonate, and then adding methyl orange and completing the titration.

Artificial solutions of alkaline salts were found to have a similar action to the natural mineral waters, and, as with them, the action varies according to the concentration of the solution. Bicarbonate of sodium has a quicker, more powerful, and more lasting effect on the composition of the bile than the sulphate of sodium, and weak solutions than strong ones.

Some colours are best developed in an acid bath, such as Cochineal Scarlet, but the presence of the bicarbonate of lime tends to cause neutralisation of the acidity, and so the dyeing is either retarded or prevented.

1/2 lb. cream of tartar 1/4 lb. bicarbonate of soda 1/4 lb. corn starch Weigh all the ingredients accurately. If the cream of tartar and the bicarbonate of soda are to be purchased from a druggist, it will be better for him to weigh them than for the housewife, as he uses scales that weigh accurately.

The lime precipitated day after day clings to the sides of the vessel in which the water is boiled, and in time they become very thickly coated. Permanent hardness is caused by other compounds of lime that are not precipitated by boiling the water. The only way in which to soften such water is to add to it an alkali, such as borax, washing soda, or bicarbonate of soda.

It is therefore destroyed by the addition of acid, and the solution is then made neutral with the solution of bicarbonate, part of which reacts with the acid, the excess remaining in solution. The reaction during titration is the following: Na AsO + I + 2NaHCO > Na AsO + 2NaI + 2CO + H O

Put two large spoonfuls of this syrup in a glass of ice-water, and stir in it one-fourth of a teaspoon of bicarbonate of soda. Any flavor can be put in this syrup. Add three eggs well beaten with sugar. Heat to a boil a pint of wine, then add spice and eggs. Stir for three minutes and serve. Crush a quart of ripe strawberries, pour a quart of water over them, and add the juice of two lemons.
