animals. By this work we know that diseases like beri-beri, scurvy,
rickets, and probably pellagra, are due to a lack of these vital
elements in the food, and from that fact these are called "deficiency"
diseases.

Of course I realize that nations can be saved from horrible diseases,
and hundreds and thousands of babies saved from death, through this
experimentation on a few guinea pigs and other animals; but what is the
life of a baby compared with the happiness of a guinea pig? Down with
animal experimentation! Let us do everything in our power to hamper
scientific work of this kind. We are giving up our husbands, fathers,
sons, perhaps to die, for the cause of humanity, but a guinea pig!
Horrors!

It has been found that the vitamines, like the minerals, are most
abundant in the outer coverings and the germ of grains, and in fruits
and vegetables. They are also present in fresh milk, butter, meat and
eggs. Babies fed pasteurized or boiled milk should have fruit juices and
vegetable purees early. Begin with one-half teaspoonful, well diluted,
and gradually increase the feeding to an ounce or more between meals
once or twice daily.

Most animal fats have the vitamines, but vegetable fats are deficient in
them. That is the reason cod liver oil is better for some therapeutic
uses than olive oil.
