head; then they are slowly lowered sideways, downward, close to the side. The next motion, which the author calls by the expressive name of the “wing-stride-standing-trunk-circling,” is performed chiefly by means of the muscles of the trunk situated around the hips. The commencing position is, hands on the hips, feet placed sideways with a distance of two feet between them. The trunk is moved from the waist, describing as large a circle as possible, first to the left, then to the right. The legs should be kept straight, the head and hips steady. Motions with the head follow, and consist simply in bending the head, first slowly forward then raised and bent as far back as possible. Then bent from left to right as far as possible without moving the rest of the body. The head is turned from left to right and followed by the _head-circling_, in which the head describes slowly as wide a circle as can be done without straining, several times to the left and then as many times to the right. After the exercise with the head come trunk movements, to be performed in the following directions, forward, backward, to the sides, and turning in a circle, the hands being kept on the hips, the chest arched and the legs straight. This is but one _prescription_, each exercise, of course, being repeated several times. Prof. Hartelius gives a great variety of exercises, a careful use of which will certainly do much for any one. There can be no vigorous, bounding life in the frame which is inert. Motion is the sign of life through all the earth and bodily motion is absolutely necessary to health. ETCHING. A style of picture most popular of late among artists and buyers is the etching. Not that it is a new style, but simply that it has been revived, perfected, and made the fashion. Etching is not new, for it dates back at least to Albert Dürer, in the first of the sixteenth century, and very probably was known before his time.
