If in idle moments the children of this generation take up a book, it is no longer a simple Bible story, or a calm classic of the English tongue, but the novels of Miss Braddon, Mrs. Southworth, or Mrs. Wood wake them into a premature life of the imagination and the senses. Before they are six years old they hold weddings for their dolls, enact love scenes in their tableaux, or go to theatrical exhibitions as stimulating as the "Black Crook," if less offensive to the taste. The skating parties and gymnastics are also fruitful sources of ill-health. The girl prepares herself for the former by inflating and over-heating her skirts over the register in the hall-floor; a few minutes' exercise chills the hot drapery--what wonder that a morbid bodily sensitiveness follows the insane exposure? No thoughtful person can watch a class of gymnasts, without seeing how extreme and unnatural are many of the attitudes assumed, especially for women. What would be thought of making bread or sweeping floors, if these compelled such attitudes, or brought about such fatigue? The sleep of these exhausted pupils is often broken, by what has been wittily called a "panorama on the brain," in which the worries, excitements, dissipations of the day, are incessantly repeated, and they rise late, more wearied than they went to bed. In spite of eminent authority to the contrary, mothers observe that it is their sons who require the largest allowance of sleep, and who keep the morning meal waiting; but if the growing girl cannot sleep, she should be compelled to lie in bed the proper number of hours, and it is obvious, that sleep like that I have described is no refreshment, and furnishes no opportunity for repair of tissue. "I want to borrow a book, doctor," said a patient the other day to a famous specialist. "Any book upon my shelves, madam," was the reply, "except those which concern the diseases of women," and the lady turned disappointed away.
