A pad composed of pieces of plaster spread on wash-leather, and of graduated sizes and kept in place by adhesive strapping,[7] answers the purpose of preventing the protrusion at the navel, and of thus facilitating the closure of the ring better than any other device with which I am acquainted. They need, however, to be continued even for two or three years, and though they should have been left off it is wise to resume their use if the child should be attacked by whooping-cough, diarrh[oe]a, or any other ailment likely to occasion violent straining. FOOTNOTES: [7] These plasters for ruptured navel in sets of a dozen are to be had of Ewen, 106 Jermyn Street, St. James's, London, and I dare say at many other places besides. CHAPTER V. ON THE DISORDERS AND DISEASES OF CHILDREN AFTER THE FIRST MONTH, AND UNTIL TEETHING IS FINISHED. =Infantile Atrophy.=--In by far the greater number of instances, the wasting of young children is due to their being fed upon food which they cannot digest, or which when digested fails to yield them proper nourishment. I quoted some figures in my introductory remarks, to show from the evidence obtained at Berlin how much larger was the proportion of deaths under the age of one year among hand-fed infants than among those brought up at the breast. Foundling hospitals on the Continent, in which the children are all drawn from the same class, and subjected in all respects to a similar treatment, except that in some they are fed at the breast, in others brought up by hand, show a mortality in the latter case exactly double of that in the former. It is as idle to ignore these facts, and to adduce in their disproof the case of some child brought up most successfully by hand, as it would be to deny that a battle-field was a place of danger because some people had been present there and had come away unwounded. But it is always well not merely to accept a fact, but also to know the reason why a thing is so. The reason is twofold: partly because the different substitutes for the mother's milk, taken for the most part from the vegetable kingdom, are less easy of digestion than the milk, and partly because, even were they digested with the same facility, they do not furnish the elements necessary to support life in due proportion.
