During the past ten years the movement of social reform has entered a fourth stage. The care of the child during his school-days was seen to be insufficient; it began too late, when probably the child's fate for life was already decided. It was necessary to push the process further back, to birth and even to the stage before birth, by directing social care to the infant, and by taking thought of the mother. This consideration has led to a whole series of highly important and fruitful measures which are only beginning to develop, although they have already proved very beneficial. The immediate notification to the authorities of a child's birth, and the institution of Health Visitors to ascertain what is being done for the infant's well-being, and to aid the mother with advice, have certainly been a large factor in the recent reduction in the infantile death-rate in England.[3] The care of the infant has indeed now become a new applied science, the science of puericulture. Professor Budin of Paris may fairly be regarded as the founder of puericulture by the establishment in Paris, in 1892, of Infant Consultations, to which mothers were encouraged to bring their babies to be weighed and examined, any necessary advice being given regarding the care of the baby. The mothers are persuaded to suckle their infants if possible, and if their own health permits. For the cases in which suckling is undesirable or impossible, Budin established Milk Depots, where pure milk is supplied at a low price or freely. Infant Consultations and Milk Depots are now becoming common everywhere. A little later than Budin, another distinguished French physician, Pinard, carried puericulture a step further back, but a very important step, by initiating a movement for the care of the pregnant woman. Pinard and his pupils have shown by a number of detailed investigations that the children born to working mothers who rest during the last three months of pregnancy, are to a marked extent larger and finer than the children of those mothers who enjoy no such period of rest, even though the mothers themselves may be equally robust and healthy in both cases. Moreover, it is found that premature birth, one of the commonest accidents of modern life, tends to be prevented by such rest. The children of mothers who rest enjoy on the average three weeks longer development in the womb than the children of the mothers who do not rest, and this prolonged ante-natal development cannot fail to be a benefit for the whole of the child's subsequent life. The movement started by Pinard, though strictly a continuation of the great movement for the improvement of the conditions of life, takes us as far back as we are able to go on these lines, and has in it the promise of an immense benefit to human efficiency.
