(1) Extend the arms straight, sideways, from the shoulder and hold them there stiff and rigid with hands open; (2) close the hands forcibly with a quick motion, pressing the fingers well into the palm; (3) open the hands forcibly and quickly, spreading out the fingers and thumbs as widely as possible forming a fan shaped hand; (4) close and open the hands as above stated, several times, as rapidly as possible. Put life into the exercise. This is a splendid exercise for developing the muscles of the hand and for acquiring manual dexterity. Exercise IX. (1) Lie upon your stomach, extending your arms above your head and then bowed upward and your legs stretched out full length and raised backward and upward. The correct position may be carried in the mind by imagining a watch--crystal or a saucer resting on the table on its middle, with both ends turning upward; (2) lower and raise the arms and legs, several times; (3) then turn over on your back and lie extended at full length, with arms extended straight out upwards over the head, with back of fingers touching the ground; (4) then raise up both legs from the waist until they stand straight up in the air, like the mast of a ship, your upper-body and arms remaining in the last position named. Lower the legs and raise them several times; (5) resume position 3, lying flat upon the back at full with arms extended straight out upward, over the head, with backs of fingers touching the ground; (6) then gradually raise body to sitting position, with arms projecting straight in front of the shoulders. Then go back gradually to the lying down position, and repeat the raising and lowering several times; (7) then turn over on the face and stomach again and assume the following position:--Keeping the body rigid from head to foot, raise your body until its weight rests upon your palms (the arms being stretched out straight in front of you) at one end, and upon your toes at the other end. Then gradually bend arms at the elbow, allowing your chest to sink to the floor; then raise up your chest and upper-body by straightening out your arms, the entire weight falling upon the arms, with the toes as a pivot--this last is a difficult motion, and should not be overdone at first.
