=Jaundice of New-born Children.=--A certain yellow tinge of the skin, unattended by any other sign of jaundice, such as the yellowness of the eye and the dark colour of the urine, is by no means to be confounded with real jaundice. It is no real jaundice, but is merely the result of the changes which the blood with which the small vessels of the skin are overcharged at birth is undergoing; the redness fading as bruises fade, through shades of yellow into the genuine flesh colour. This is no disease, to be treated with the grey powder and the castor oil wherewith the over-busy monthly nurse is always ready. It is a natural process, which the intelligent may watch with interest, with which none but the ignorant will try to interfere. There is, however, beside this a real jaundice, in which the skin is more deeply stained, the whites of the eyes are yellow, the urine high-coloured, and in which the dark evacuations that carry away the contents of the bowels before birth are succeeded by white motions, from which the bile is absent. This condition is not very usual, save where children have been exposed to cold, or where the air they breathe is unwholesome. Of this no better proof can be given than is afforded by the fact that in the Dublin Lying-in Hospital, where the children are defended with the greatest care both from cold and from a vitiated atmosphere, infantile jaundice is extremely rare, while it attacks three-fourths of the children received into the Foundling Hospital of Paris. Still it does sometimes occur when yet no cause can be assigned for it, and it is noteworthy that it is sometimes met with in successive infants in the same family. As the respiratory function and that of the skin increase in activity, the jaundice will disappear of its own accord. Great attention must be paid during its continuance to avoid exposure of the child to cold, while no other food than the mother's milk should be given. If the bowels are at all constipated, half a grain of grey powder or a quarter of a grain of calomel may be given, followed by a small dose of castor oil, and the aperient will often seem to hasten the disappearance of the jaundice; but in a large number of cases even this amount of medical interference is not needed. There is, indeed, a very grave form of jaundice, happily of excessive rarity, due to malformation of the liver, to absence or obstruction of the bile-ducts, and often accompanied with bleeding from the navel. I do but mention it; the intensity and daily deepening of the jaundice, the fruitlessness of all treatment, and the grave illness of the child, even though no bleeding should occur, render it impossible to confound this hopeless condition with the trivial ailment of which I have been speaking. The next chapter will furnish a fitter place than the present for speaking fully of the Disorders of the Digestive Organs.
