In this non-imitative and merely indicative treatment there is room for all sorts of technical inaccuracies. Form is woefully misapprehended, as in the circular trunk, the oblong mouth, the claw foot, and so forth. Proportion—even in its simple aspect of equality—is treated with contempt in many instances (_cf._ the legs of the quadruped and the bird in Fig. 45 (_a_), (_b_), and (_c_) (p. 375)). What is no less important, division of space and relative position of parts, which seem vital even to a diagrammatic treatment, are apt to be overlooked, as in drawing the facial features high up, in attaching the arms to the head, and so forth. Even the element of number is made light of, and this, too, in such simple circumstances as when drawing the legs of an animal. [Illustration: Fig. 51 (_a_).] One of the most curious of these misrepresentations comes into view in the third or sophisticated stage, _viz._, the introduction of more than is visible. This error, again, assumes a milder and a graver form, _viz._, (_a_) the giving of the features more distinctly and completely than they appear in the object represented, and (_b_) the introducing of features which have no place in the object represented. Examples of the first are the introduction of the nasal angle into the front view of the human face; the separation throughout their length of the four legs of the horse; and such odd tricks as detaching the reins of the horse from the animal, as in Fig. 51 (_a_). Illustrations of the second are numerous and varied. They include first of all the naïve introduction of features of an object which are not on the spectator’s side and so in view, as the second eye and the second arm in what are predominantly profile representations. With these may be classed the attempt to exhibit three sides of a house. Closely related to these errors of perspective is the exposure of objects or parts of objects which are covered by others. It is possible that the spread-eagle arrangement of the two joined arms is an attempt to represent a feature of childish anatomy, _viz._, the idea that the arms run through and join in the middle of the trunk. A clearer example of this attempt to expose to view what is covered is the exhibition of the whole human figure in a boat, house or carriage. With this may be compared the disclosure of the whole head of a horse when drinking, as in the accompanying drawing by a boy of five (Fig. 51 (_b_)), of the whole head of the man through his hat (see above, p. 350, Fig. 20 (_b_)), and of the human limbs through the clothes (Fig. 41, p. 371).
