In relation to the _amount_ of the discharge, every woman is a law unto herself. Usually, it is four or five ounces in all. Habits of life are apt to modify it materially. Here, again, those exposed to prolonged cold and inured to severe labor escape more easily than their sisters petted in the lap of luxury. Delicate, feeble, nervous women--those, in other words, who can least afford the loss of blood--are precisely those who lose the most. Nature, who is no tender mother, but a stern step-mother, thus punishes them for disregarding her laws. Soft couches, indolent ease, highly spiced food; warm rooms, weak muscles,--these are the infractions of her rules which she revenges with vigorous, ay, merciless severity. It is well known, too, that excitement of the emotions, whether of anger, joy, grief, hatred, or love increases the discharge. Even the vulgar are aware of this, and, misinterpreting it as half-knowledge always does, suppose it a sign of stronger animal passions. It bears no such meaning. But the fact reads us a lesson how important it is to cultivate a placid mind, free from strong desire or fear, and to hold all our emotions in the firm leash of reason. Physicians attach great importance to the _character_ of the discharge. It should be thin, watery, dark-coloured, and never clot. If it clots, it is an indication that something is wrong. THE DANGERS OF PUBERTY. We have shown that there are constantly individual deviations, quite consistent with health, from any given standard. They only become significant of disease when they depart decidedly from the average, either in the frequency of the illness, its duration, the amount of the discharge, or the character. More or less pain, more or less prostration and general disturbances at these epochs, are universal and inevitable. They are part of the sentence which at the outset He pronounced upon the woman, when He said unto her, 'I will greatly multiply thy sorrow and thy conception.' Yet with merciful kindness He has provided means by which the pain may be greatly lessened, and the sorrow avoided; and that we may learn and observe these means, their neglect often increases a hundred-fold the natural suffering. At this critical period, the seeds of hereditary and constitutional diseases manifest themselves. They draw fresh malignancy from the new activity of the system. The first symptoms of tubercular consumption, of scrofula, of obstinate and disfiguring skin diseases, of hereditary insanity, of congenital epilepsy, of a hundred terrible maladies, which from birth have lurked in the child, biding the opportunity of attack, suddenly spring from their lairs, and hurry her to the grave or the madhouse. If we ask why so many fair girls of eighteen or twenty are followed by weeping friends to an early tomb, the answer is, chiefly from diseases which had their origin at the period of puberty.
