When the nature of these swellings was not understood, they used to be poulticed, and to be opened with a lancet to let out their contents. We know now, however, that we have nothing to do but to let them alone; that by degrees the blood will be absorbed and the tumour will disappear, and as it does so we may trace the gradual transformation of the membrane which covered it into bone, as we feel it crackling like tinsel under the finger. Two, three, or four weeks may be needed for the entire removal of one of these blood-swellings. The doctor will at once recognise its character, and you will then have nothing to do but to wait--often, unhappily, so much harder for the anxious mother than to meddle. =Ruptured Navel.=--There is a period some time before the birth of a child when the two halves of its body are not united in front, as they become afterwards; and hare-lip or cleft-palate sometimes remains as the result of the arrest of that development which should have closed the fissured lip or united the two halves of the palate. In a similar way it happens sometimes that though the skin is closed, the muscles of the stomach (or, more properly speaking, of the belly) are not in the close apposition in which they should be, so that the bowels are not supported by the muscles, but protected only by the skin. More frequently than this, especially in the case of children who are born before the time, the opening through which the navel string passes is large at birth, and fails to close as speedily and completely as it should do afterwards. When everything goes on as it ought, the gradual contraction of the opening helps to bring about the separation of the navel string and its detachment, and the perfect closure of the opening takes place at the same time, between the fifth and the eighth day after birth. If this does not occur, the bowels are very apt to protrude through the opening, and if allowed to do so for weeks or months, the opening becomes so dilated that its closure is impossible, and the child grows up afflicted permanently with rupture through the navel. This is always an inconvenience, sometimes even a source of serious danger; but if means are taken to prevent the condition becoming worse, nature seldom fails eventually to bring about a cure, and to effect the complete closure of the opening. If the muscles on either side do not come into apposition, but leave a cleft between them, the infant should constantly wear a broad bandage of fine flannel round the stomach, not applied too tightly, in order to give support. The circular bandages of vulcanised india-rubber with a pad in the centre are nowise to be recommended. The pad is apt to become displaced, and to press anywhere but over the navel, while its edges irritate the infant's delicate skin, and the pressure which it exerts if it is sufficiently tight to retain its place interferes with respiration.
