roughly from eight to twelve. The second set of teeth is almost completed during this period, the first molars appearing in the seventh year. At its commencement the brain has nearly reached its full adult weight, the slight addition being made mostly during this period. It is now that the development of the sensory and motor areas of the brain takes place, and particularly of the association fibres that connect these; and control is established over the accessory muscles. The boy possesses an all-devouring curiosity or sensory and motor hunger, but his inquiries and experiments are not deep and far-reaching; his investigations are, indeed, rather physical than intellectual, rather to satisfy his sense-hunger and muscle-hunger than any true intellectual craving. His efforts are extremely tentative and capricious, and he is incapable of sustained interest in definite problems. The boy is completely developed for individual life; and is well adapted to living, independently of his parents, just such a life as is led by savages. Both these characteristics display themselves particularly in his plays, which owe their existence and their interest to the fact that they are the relics of the serious occupations of his savage ancestry. From seven to twelve, games are almost exclusively individualistic and competitive. The boy's games are predominantly physical, open-air games from the eighth year on. Games of chase are particularly prominent, especially at nine. The boy is eminently active and practical, his energy going rather to activity than to growth, this being the most active period of life. He is self-centred and independent, lives in the real and the actual, and has little interest in ideals, being quite satisfied with himself and his surroundings, if only he be left his freedom. He looks backward rather than forward, and lives in the present and the past rather than the future. He has the keenest interest in history and biography, and especially in tales of active life, of battle and adventure and exploration, of other times and other lands and other peoples. What is said of the boy holds true to a considerable extent of the girl. Apart from running games, however, the girl's amusements are chiefly imitative, and centre mainly in the doll, notably in the ninth year. "The number of motor-activities," says Dr. Hall, "that are both inspired and unified by this form of play, and that can always be given wholesome direction, is almost incredible, and has been too long neglected both by psychologists and teachers. Few purer types of the rehearsal by the individual of the history of the race can probably be
