author believes that nervousness—"strictly, deficiency or lack of nerve-force"—is a modern affection, and that it is manifested in the United States through a variety of symptoms that are peculiar in many respects to the country, and remarkable. He ascribes its great development and rapid increase chiefly and primarily to modern civilization, which is different from the ancient civilization by a number of characteristics which breed mental activity and anxiety about time-tables, and excitements about matters of politics and business, for which the ancients had only a limited concern. It is aided by secondary and tertiary causes which might be comparatively unimportant in themselves alone, but which, combined with each other and with the chief cause, exert each its own kind and degree of effect. The symptoms by which this nervousness is manifested, numerous as they are, and unpleasantly as they often exhibit themselves, do not all betoken ill to the country; for brain-workers have in all ages been long lived, longevity increases apace with nervousness; good taste, the beauty of women, the faculty of humor, the eloquence of oratory, increase with it; the evil of it tends, within certain limits, to correct itself; "and the physical future of the American people," says the author, "has a bright as well as a dark side; increasing wealth will bring increasing calm and repose; the friction of nervousness shall be diminished by various inventions; social customs shall be modified, and as a consequence strength and vigor shall be developed at the same time with, and by the side of, debility and nervousness."

It is about these books, the method of preserving them, their enemies, the places in which to hunt for them, that the following pages are to treat."
