as much common table
salt as can be dissolved.
2. A teaspoon of mustard in a large glass of warm water.
3. A teaspoon of syrup of ipecac, repeated in fifteen minutes
if necessary.

Any one of these emetics is useful in instances where it is desirable
to empty the stomach at once.

A CALORIE

A calorie is the heat unit used in the estimation of the fuel value of
various foods. For instance, an ordinary slice of homemade bread
contains 100 calories. An ordinary fig contains almost 100 calories. A
large orange or an apple or a glass of grape juice contains about 100
calories. There are 100 calories in three teaspoons of sugar or honey.

A complete food list with the estimation of calorie value of foods is
found in _The Science of Living_, page 370, while on page 99 of the
same book is a very helpful table showing the amounts of various foods
required to equal 100 calories. The reader will find this exceedingly
practical in estimating food values for the household.

ACIDIFYING AND ALKALINIZING FOODS

Since we find that in all acute diseases the acidity of the urine is
greatly increased and in time of health it is less acid, we submit two
lists of foods which tend to acidify the urine or to alkalinize the
urine.

FOODS WHICH TEND TO ACIDIFY.

1. _Animal Foods_: All forms of flesh foods, fish, fowl, etc.,
including all kinds of meat broths, soups, beef tea, bouillon, etc.

2. _Eggs._ 3. _Breadstuffs_: All kinds of breads, whether made of
wheat, rye or corn, crackers, toasts, griddle cakes, etc. 4.
_Pastries._ All sorts of pies and cakes--except fruit pies, and other
desserts containing milk or sour fruits.

5. _Cereals_: Rice, oatmeal, and breakfast foods of all kinds,
including the flaked and toasted breakfast foods.

6. _Peanuts_, plums, prunes, and cranberries. Plums and cranberries
fall in this column because of their benzoic acid, which the body
cannot fully oxidize.

FOODS WHICH TEND TO ALKALINIZE.

1. _Dairy Products_: Milk, ice cream, cottage cheese, cheese,
buttermilk, etc.

2. _Potatoes_ and _bananas_.

3. _Soups_: All forms of vegetable and fruit soups and broths.
