in any case, but after measuring
carefully the other ingredients enough water should be added to bring
the total up to the amount required.

_How great an increase in the quantity should be made at one time?_

One may make up five ounces additional food; but the first two days
only two or three ounces of the additional amount should be given; the
next two days, four ounces; after two days more, the five ounces may
be given.

The increase in the quantity given at a single feeding should not be
more than a quarter of an ounce.

FOOD FOR HEALTHY INFANTS--THE LATER MONTHS

_How long should the fat be as much as three times the proteids?_

This is seldom of advantage longer than three or four months.

_What changes should then be made in the milk?_

After Formula V of the First Series (6 ounces of 10-per-cent milk in
20 ounces of food) has been reached, the fat should be increased very
slowly for this proportion (3 per cent) is near the limit for most
healthy children. The milk should now be strengthened chiefly by
raising the percentage of proteids.

_How is this accomplished?_

The 10-per-cent milk and the formulas derived from it should now be
discontinued, and those made from 7-per-cent milk used.

_Third Series_

_Formulas for the Later Months from 7-per-cent Milk_

-----------------------------------------------------------
I. II. III. IV. V.

7-per-cent milk 7 oz. 8 oz. 9 oz. 10 oz. 11 oz.
Milk sugar 1 " 1 " 1 " 3/4 " 1/2 "
Lime-water 1 " 1 " 1 " 1 " 1 "
Boiled water 12 " 11 " 10 " 4 " 3 "
Barley gruel 0 " 0 " 0 " 5 " 5 "

20 oz. 20 oz. 20 oz. 20 oz. 20 oz.
-----------------------------------------------------------

Since the sugar dissolves, the total will be twenty ounces in each
column.

Of any of the formulas, 25 ounces is made by using one quarter more
of each ingredient; 30 ounces, by using one half more; 35 ounces, by
using three quarters more; 40 ounces, by using twice as much, exactly
as described in the First Series on page 73.

The approximate composition of these formulas expressed in percentages
is as follows:
