The arms, being the thin lanky members, are, like the legs, commonly represented by lines. The same thing is noticeable in the drawings of savages. They appear, in the front view of the figure, as more or less stretched out, so as to show beyond the trunk; and their appearance always gives a certain liveliness to the form, an air of joyous expression, as if to say, "Here I am!" (see Fig. 13, the drawing of a boy of six).

In respect of their structure a process of gradual evolution may be observed. The primal rigidity of the straight line yields later on to the freedom of an organ. Thus an attempt is made to represent by means of a curve the look of the bent arm, as in the accompanying drawing by a boy of five (Fig. 14). In other cases the angle of the elbow is indicated. This last improvement seems to come comparatively late in children's drawings, which here, as in other respects, lag behind the crudest outline sketches of savages.
