Formulas for the Early 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 oz. | 1 oz. | 1 oz. | ¾ oz. | ½ oz. |
| Lime-water | 1 oz. | 1 oz. | 1 oz. | 1 oz. | 1 oz. |
| Boiled water | 12 oz. | 11 oz. | 10 oz. | 4 oz. | 3 oz. |
| Barley gruel | 0 oz. | 0 oz. | 0 oz. | 5 oz. | 5 oz. |
| 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:
| FORMULA. | Fat. | Sugar. | Proteids. |
| I. | 2.50 | 6.50 | 1.25 |
| II. | 2.80 | 6.50 | 1.40 |
| III. | 3.15 | 7.00 | 1.55 |
| IV. | 3.50 | 6.00 | 1.75 |
| V. | 4.00 | 6.00 | 2.00 |
How should the food be increased during this period?
Beginning with I of this Series, which should usually follow V of the First or Second Series (pages 70, 71), the increase may generally be made in a week or ten days to II; in about two weeks more to III; now more slowly to IV and V. When IV or V has been reached, the same formula may sometimes be continued for three or four months with no other change than an increase in the quantity.
In passing from Formula V of the First Series to Formula I of the Third Series the proportion of fat is at first reduced. Is this necessary or important?
