_The Ankles._--Holding leg stiff in front, work the foot at ankle, up, down, to the right side, to the left; shake and twist feet, and "roll" them, doing part of the work with a reverse motion; rise on the toes, with a regular motion, and then slower, holding the body balanced on the toes for a few seconds. _Further Balance-work._--Throwing the weight of the body on the ball of one foot, lift the other leg, and flexing at knee, describe circles, moving the leg from the knee only. _Step._--Pointing toe, and arching instep, and with stiff leg; to the front, and back to place; to the side; to the back; across at back. These motions, out of a large number, were selected for their simplicity and usefulness for regular daily exercise. THE INCANTATIONS OF ALI BEN MESROUR. BY W. A. CURTIS. The fame of Ducardanoy and Bouchardy spread through Algeria. Tho methods by which they had deceived and despoiled the Arab tribes gradually became known, and threats of vengeance coming to their ears, they decided that it was no longer safe to dwell so near the Sahara and its wild tribes, and they removed to the northern side of the Atlas. But even in their new home they were destined to encounter the power of the Shiekh of the Mountain of Singing Sauds, though not in a way that menaced their personal safety. It was at the close of the Mohammedan fasting season of Ramadan that the great Arabian magician Ali Ben Mesrour came to town. Bouchardy, who attended all of his performances, declared his feats to be easy of execution, and their mechanism readily detected by the most unobserving. Ducardanoy was inclined to attribute this to professional jealousy; but when the magician began to cure the halt and lame among the Arabs of grievous corns and bunions, he too denounced Ben Mesrour as a bungler and a charlatan. Hearing of the criticisms of the two experts, the Arab sage gravely sent them a challenge. He announced that if they dared to give him a trial he would appear at their house, and by a certain magical process change the one into a dromedary and the other into a mule, and he agreed that in case of failure there should be forfeited two five-franc pieces of silver, which he would deposit with the commandant of the garrison previous to the trial. Two five-franc pieces were nothing to the chiropodist and the prestidigitator, grown exceedingly wealthy with the prudent investment of the results of their late encounters with the Arabs, but they hailed with pleasure the prospect of amusing themselves at the expense of the magician.
