Rickets is owing to a want of a sufficient quantity of earthy matter in the bones; hence the bones bend and twist, and lose their shape, causing deformity. Rickets generally begins to show itself between the first and second years of a child's life. Such children are generally late in cutting their teeth, and when the teeth do come they are bad, deficient of enamel, discoloured, and readily decay. A rickety child is generally stunted in stature; he has a large head, with overhanging forehead, or what nurses call a watery-head-shaped forehead. The fontanelles, or openings of the head, as they are called, are a long time in closing. A rickety child is usually talented; his brain seems to thrive at the expense of his general health. His breast-bone projects out, and the sides of his chest are flattened; hence he becomes what is called chicken-breasted or pigeon-breasted; his spine is usually twisted, so that he is quite awry, and, in a bad case, he is hump-backed; the ribs, from the twisted spine, on one side bulge out; he is round-shouldered; the long bones of his body, being soft, bend; he is bow-legged, knock-kneed, and weak-ankled. Rickets are of various degrees of intensity, the humpbacked being among the worst There are many mild forms of rickets; weak ankles, knocked-knees, bowed-legs, chicken-breasts, being among the latter number. Many a child, who is not exactly hump-backed, is very round-shouldered, which latter is also a mild species of rickets. Show me a child that is rickety, and I can generally prove that it is owing to poor living, more especially to poor milk. If milk were always genuine, and if a child had an abundance of it, my belief is that rickets would be a very rare disease. The importance of genuine milk is of national importance. We cannot have a race of strong men and women unless, as children, they have had a good and plentiful supply of milk. It is utterly impossible. Milk might well be considered one of the necessaries of a child's existence. Genuine, fresh milk, then, is one of the grand preventatives, as well as one of the best remedies, for rickets. Many a child would not now have to swallow quantities Of cod-liver oil if previously he had imbibed quantities of good genuine milk. An insufficient and a poor supply of milk in childhood sows the seeds of many diseases, and death often gathers the fruit. Can it be wondered at, when there is so much poor and nasty milk in England, that rickets in one shape or another is so prevalent?
