I will say now but this: that whatever a mother may do eventually, she avoids grave perils for herself by suckling her infant for the first month; while the health of her child, just launched upon the world, is terribly endangered if fed upon those substitutes for its proper nutriment on which after the lapse of a few weeks it may subsist, may even manage to thrive. There are some local affections incident to the new-born child concerning which a few words may not be out of place; and first of the =Ophthalmia of New-born Children.=--It is the cause of the loss of sight of nine-tenths of all persons who, among the poor, are said to have been born blind. In the wealthier classes of society it is comparatively rare, and seldom fails to meet with timely treatment, yet many people scarcely realise its dangerous character, or the extreme rapidity of its course. It generally begins about the third day after birth with swelling of the lid of one or other eye, though both are soon involved. The eyelids swell rapidly, and if the affection is let alone, they soon put on the appearance of two semi-transparent cushions over the eyes. On separating the lids, which it is often very difficult to do owing to the spasmodic contraction of the muscles, their inner surface is seen to be enormously swollen, bright red, like scarlet velvet, bathed in an abundant yellowish thin secretion, which often squirts out in a jet as the lids are forcibly separated. Great care must be taken not to allow any of this fluid to enter the eye of a bystander, nor to touch his own eye until the fingers have been most carefully washed, since the discharge is highly contagious, and may produce most dangerous inflammation of the eyes of any grown person. The discharge being wiped or washed away, the eye itself may be seen at the bottom of the swelling very red, and its small vessels very blood-shot. By degrees the surface of the eye assumes a deeper red, it loses its brightness and its polish, while the swelling of the lids lessens, and they can be opened with less difficulty; their inner surface at the same time becomes softer, but thick and granular, and next the eyes themselves put on likewise a granular condition which obscures vision. The discharge by this time has become thicker and white, and looks like matter from an abscess. By slow degrees the inflammation may subside, the discharge lessen, the swelling diminish, and the eye in the course of weeks may regain its natural condition. But the danger is--and when proper treatment is not adopted early the danger is very great--lest the mischief should extend beyond the surface of the eye, lest ulceration of the eye should take place, the ulceration reach so deep as to perforate it, and not merely interfere with the sight, but destroy the organ of vision altogether.
