So long as a child seems pretty well in the intervals between the fits of coughing, as the hurried breathing subsides after each to a natural frequency, as a long loud hoop follows each cough, as vomiting takes place only after a fit of coughing and never in the intervals, as the child becomes flushed only and not livid during a cough, and recovers itself perfectly afterwards, as it does not complain of constant headache, nor spits blood, nor has nose-bleeding, nor is feverish, nor depressed, nor drowsy, you may feel happy about it. When any of the symptoms just enumerated show themselves you have reason for grave solicitude, and the child requires daily medical watching. One word in conclusion. A child who has recently had hooping-cough is more liable than another to be attacked by chicken-pox or measles; and, moreover, imperfect recovery from hooping-cough is apt, especially if there is any tendency to consumption in the family, to be followed by consumptive disease. =Asthma.=--_Asthma_, attended by distress of breathing quite as considerable as in the grown person, is by no means unusual in the child. Recovery from it is far more likely to take place in the latter, since it is almost always independent of those diseases of the heart or lungs, which in the former occasion or aggravate it. It belongs to the class of what has been termed nervous asthma and is observed with special frequency in children who, when younger, had been liable to catarrhal croup; spasm of the air-tubes having taken the place of the previous spasm of the windpipe. Independently of that antecedent it comes on sometimes about the time of the second teething in nervous and impressionable children, in whom an attack may be produced by indigestion, constipation, or over-fatigue. It is also by no means rare in children in whom that skin affection, eczema, of which I have already spoken, outlasts the time of infancy, and becomes general and severe. The improper performance of the functions of the skin seems to cause a peculiar sensitiveness of the air-tubes, and to render them liable to the occasional occurrence of that spasm which produces asthma. These cases are less hopeful than others, and the liability to the attacks ceases only when the skin-affection has been completely cured; a reason this for not neglecting eczema in infancy and early childhood. Sometimes, too, it follows frequently-recurring attacks of bronchitis, and, though less often than might be expected, it succeeds severe hooping-cough, and in these two conditions the prospects of recovery are less hopeful than in the others.
