    Artificial Feeding The third week of lactation, albumin decreases, casein increases. Irre- mediable difference between woman's and cow's milk is gradually eliminated. With increase in size of pylorus, of contractile and propulsive power of stomach, achild becomes adapted to digestion of properly modified cow's milk. Every breast-fed child should have one bottle from third week; two bottles after first month. This allows mother needed uninterrupted rest at night; desirable freedom in the day, accustoms digestion to an artificial food, makes weaning easy at any period. Neglect of this precaution renders weaning perplexing and distressful. From one cause or another there are cases in which there is no alterna- tive but artificial feeding from birth. The problem of a substitute for human milk for the new-born has constantly to be faced. A superior quality of woman's milk must be the standard for a sub- stitute. To deduce as standard the average of one hundred analyses, from 1.30 to 7.61 per cent, fat, is fallacious. Unquestionably a physician would select the best, not an average, or medium, wet-nurse; undoubtedly a fac- simile of her milk is the only unimpeachable substitute. The deduction that the average of one hundred analyses, good and poor, is the type-food, is unscientific and untenable. Gravity cream has a relatively low percentage of casein, a high per- centage of fat. A duplicate of woman's milk is readily prepared from it. Eternal, Inviolable Basic Principles Abundant Fat. Flocculent, Feathery Proteid For correct percentages of casein and fat for first weeks; for physical behavior proportional to narrow pylorus, milk must be sixteen hours old, and only top half-ounce of cream removed. The subjoined table shows the percentages of proteid and fat in different cream layers, and the ratio of proteid to fat. Fat and Proteid as Found in a Series of Analyses Portion Taken.
