With these we class especially the so-called "soda water"and the ordinary "seltzer" (not to be confounded with the true "natural selters" and its imitation on pages 573, 574). These waters are preferred for their thirst-quenching qualities and are often taken with tonics or stomachics, etc. They should possess an agreeable, a not too saline taste, and be rich in carbonic acid gas.

"Soda-water" is customarily put up in bottles, and generally charged as high as 80 and even 100 pounds; when in syphons up to 120 and 140 pounds.

"Seltzer-water" is filled into syphons under 120 to 140 pounds of pressure.

Formula for Soda-Water.

For 10 gallons of water = 80 lbs.

Formula 1, (Plain). Sodium carbonate..... 5 ounces.

Formula 2, (English). Sodium carbonate.....from 8 to 12 ounces.

Formula 3, (Mixed). Sodium carbonate ....". 3 to 9

Sodium chloride (table salt). " 2 to 3 drachms. Calcium chloride.....". 2 to 3 "

Formula 4, (Mixed). Sodium chloride.......... 500 grains.

Sodium carbonate,.........9000 "

It will be noticed that the addition of small quantities of sodium chloride (table-salt) or calcium chloride to "soda-water" considerably improves the taste.

Plain - Natrokrene.

For 10 gallons of water = 80 lbs.

Sodium carbonate............from 12 to 24 ounces.

Potass Water.

Water.......................10 gallons.

Bicarbonate of potassium............. 6 ounces.

Seltzer Waters.

For 10 gallons of water - 80 pounds. There are many formulae employed. They should include the principal components of the natural "selters" (pages 573, 574) and be so modified as to give the carbonated water an agreeable taste and make it a re-feshing beverage. We append the following approved formulae, leaving it to the intelligence of the carbonator to select one that suits him best, making it his standard combination.

The proportions of these formulae may be changed to suit the taste; in fact, these components may be used in varying proportions.

Flavored Mineral Water.

Bicarbonate of soda or potash is much preferred for making saline draughts with citric or tartaric acid; and when flavored with a little tincture, or essence of orange or lemon, etc., it forms a most delicious effervescing beverage.

Water..................

10 gallons

Bicarbonate of soda..................

2 to 5 ounces.

Tartaric acid solution................

4 to 6 "

Sugar if desired

8 to 12 "

Essence of lemon

4 drachms

For Bottling.

Citrate of Magnesia Water.

Water .......................

10 gallons.

Citric or tartaric acid solution..................

2 ounces.

Agitate, then add :

Carbonate of magnesia................

5 ounces

Syrup..............
