which thereafter act as most violent
poisons and may cause death. Sensitization to animal proteins is much
the more frequent. In such cases nut products become a very precious
resource. This is especially true with reference to cow's milk.

Liquid nut preparations have saved the lives of hundreds of infants
within the last twenty years. I have had the pleasure of meeting several
fine looking young people who owed their lives to nut-feeding when other
resources had failed. One case was particularly interesting. A telegram
from a well-known Senator at Washington announced the fact that his
infant daughter and only child was dying from mal-nutrition, as cow's
milk and all the known infant foods had been found to disagree. I
advised nut-feeding, and fortunately the prescription suited the case
and the little one began to improve at once. When the physician in
attendance learned that the child was eating nuts he vigorously
protested, declaring that such a diet was preposterous and would
certainly kill the infant, but the child flourished wonderfully on the
liquid nut diet, eating almost nothing else for the first three years of
her life, and today is a splendidly developed young woman, a brilliant
witness to the food value of nuts.

I have by no means exhausted the physiologic phases of my subject, but
will now turn a moment in concluding my paper, to its economic aspects.

The high price of nuts is constantly urged as an objection to their use
as a staple. It is probable that a largely increased demand would lead
to so great an increase in the supply that the cost of production, and
hence the cost to the consumer, would be decreased. But even at the
present prices the choicest varieties of nuts are cheaper than meats if
equivalent food values are compared. This is clearly shown by the
following table which indicates the amounts of various flesh foods which
are equivalent to one pound of walnut meats.
