That the modern development of infant feeding will serve to replace natural lactation, must be denied, and this without prejudice to the magnificent work of the late Professor Budin of Paris and Professor Morgan Rotch of Harvard. These pioneers and their followers have devised some admirable second bests--admirable, that is, relatively to some of the pitiable methods which they have superseded, but relatively to the mother's breast not admirable at all. At the beginning of the campaign against infant mortality, the creche and the sterilized milk depot and the fractional analysis of cow's milk and its recomposition in suitable proportions of proteid, fat, etc., as devised by Rotch, were rightly acclaimed and admitted to save vast numbers of infant lives. All this is mere stop-gap, wonderfully effective, no doubt, but only stop-gap nevertheless. In France they are going ahead, and public opinion in London is being slowly persuaded to follow along the more recent French lines. The modern principle upon which we should act is Nature's principle--saving the children through their mothers. Expectant motherhood must be taken care of; we must feed, not the child, but the nursing mother, and the child through her. If we rightly take care of her, she will construct a perfect food for the child. There is no other path of racial safety. It is not our present concern to deal with the problems of infancy and childhood as they require, and surely we need not wait to prove that nursing motherhood cannot safely be superseded, but must be retained and safeguarded. If this postulate be granted, we have to determine how it comes about that the German figures, for instance, are showing this extraordinarily rapid decline in maternal lactation. As has already been noted in passing, we must reject the suggestion that the natural type of women is changing. Such a change of natural type in any living race can occur only through selection for parenthood, and such selection in the case in question can scarcely be imagined to occur in the direction of choosing women who are naturally less capable of nursing. On the contrary, the tendency of the selective principle must always be toward the greater survival of infants whose mothers can nurse them, and who in their turn, if they are to be women, will be more likely to be able to nurse their children. Further, the action of selection cannot demonstrate itself more quickly than is permitted by the length of human generations. It must therefore be rejected as any interpretation of this case. If women are ceasing to be able to nurse their babies, and if this change is occurring with such extraordinary rapidity as the German figures indicate, plainly the explanation must be found in the action of some recent and novel condition or conditions upon womanhood.
