d skimmed milk in the mixture; 30 ounces in
a 48-ounce mixture will give 30/48 of 3.20% of protein, or 2.00% of
protein. Both gravity cream and skimmed milk also contain 4.50% of
sugar. Thirty ounces of gravity cream and skimmed milk in a 48-ounce
mixture will therefore furnish 30/48 of 4-1/2 which is the same as
30/48 of 9/2 or almost 3.00% of milk sugar. Four rounded
tablespoonfuls of milk sugar are equal to two ounces. Two ounces of
sugar in a 48-ounce mixture is equal to 2/48 of 100% or 4%. The total
percentage of sugar is, therefore, 7%. Two teaspoonfuls of barley
flour in a pint of water makes a 1.50% decoction of starch. Twelve
ounces of barley water of this strength in a 48-ounce mixture will
give 12/48 of 1.50% or about 0.35% starch. There are six ounces of
limewater in the mixture and 30 ounces of gravity cream and skimmed
milk. 6/30 of 100% is 20%. The limewater is, therefore, 20% of the
milk and cream. The mixture thus contains 4% fat, 7% sugar, 2%
protein, and 0.35% starch, while the limewater is in the proportion of
20% of the cream and milk."

If, therefore, the nurse will follow out the plan suggested by Drs.
Morse and Talbot, it should be a simple matter to change the
percentage of any of the food constituents in any formula.

The following schemes for feeding well babies are included to
facilitate the work in the home. A nurse may teach the mother the
manner in which these schemes are used, keeping in mind that there can
be no iron clad rule for feeding all babies. No nurse should recommend
a formula without directions from a physician. And no formula should
be changed without his permission.
