Then, if a physician is called in, and gives her iron, and tells her nothing is the matter, or is himself alarmed, and imagines she has heart disease or consumption, it is a chance if she does not rapidly sink, out of mere fright and over-much dosing, into some fatal complaint. Let it be well understood that chlorosis, though often obstinate and obscure, is always curable if properly and promptly treated. The remedies must be addressed to the nervous system, and can be administered with intelligence only by a competent medical adviser. It can be prevented by a hygienic mode of life, and, as its most common causes are anxiety, home-sickness, want of exercise, or overwork at school, nothing is so salutary in its early stages as a change of air and scene, cheerful company, a tour to the mountains or some watering-place, and regular exercise. Many young women suffer considerable pain during their monthly illness. This may arise from many different causes, such as, congestion, inflammation, malformation, or a wrong position of the parts, or over-sensitive nerves. They can only be successfully treated when the cause is known; and they may rest assured that this suffering, in nearly every case, can be removed. Sometimes a girl grows to the age of eighteen or twenty without having her periodical changes. We have already said that this is not unusual in some climates and in some families; so, as long as the general health is good and the spirits cheerful,--always an important point,--it need cause no anxiety. But if the health grow poor, and especially if there be pains and weakness recurring monthly without discharge, then something is wrong, and the doctor should be consulted. HYSTERICS. There is a disease of the nerves to which girls about the age of puberty are very subject, particularly in the higher circles of society, where their emotions are over-educated and their organization delicate. It is called hysteria, and more commonly _hysterics_. Frequently it deceives both doctor and friends, and is supposed to be some dangerous complaint. Often it puts on the symptoms of epilepsy, or heart disease, or consumption. We have witnessed the most frightful convulsions in girls of fourteen or fifteen, which were brought on by this complaint. Sometimes it injures the mind; and it should always receive prompt and efficient attention, as it is always curable. This disease is apt to produce a similar affection in other girls of the same age who see the attacks. For this reason, hysterical girls should not be sent to large schools, but cured at home. Often a strong mental impression restores them. The anecdote is told of a celebrated surgeon (Boerhaave) who was called to a female seminary where there was a number of hysterical girls. He summoned them together, heated a number of iron instruments before their eyes, and told them that the first one who had a fit should be cauterized down the spine. They all recovered immediately.
