to the growth of the whole organism, and therefore without too many-hours of mental work, with plenty of play and rest, and in well-ventilated school-rooms. During the period of childhood few girls will overwork themselves. If it is done, it is by outside pressure, and any bad effects are usually temporary, and easily got over by a little rest, and a good holiday in the country.
The era of adolescence is one of the greatest importance from a bodily and mental point of view in young men and women, but especially in the latter. Bodily, the child eats, sleeps, grows, plays, and does what she is told. Life has no seriousness. Everything in the body and mind is inchoate and unformed. Nothing indicates permanence. There are great and constant muscular energy, noise, sound sleep, quick digestion. The delights of life consist in sweets and games, the imagination is shallow, the affections are instinctive, "character" is nascent; there is no morality in any correct sense, and no real religious sentiment. There is little liability to nervous diseases except those affecting the muscular system; there are no neuralgias, no liability to mental diseases, and most other diseases are sharp and soon over.

Literature and poetry begin to be understood in a vague way, and the latter often becomes a passion. The imagination becomes strengthened, and is directed into different channels from before. The sense of right and wrong and of duty becomes then more active. Morality in a real sense is possible. A sense of the seriousness and responsibility of life may be said then to awaken for the first time. The knowledge of good and evil is acquired. The religious instinct arises then for the first time in any power. Modesty and diffidence in certain circumstances are for the first time seen. The emotional nature acquires depth, and tenderness appears. The real events and possibilities of the future are reflected in vague and dream-like emotions and longings that have much bliss in them, but not a little too of seriousness and difficulty. The adolescent feels instinctively that she
