[Illustration: Fig. 29 (_b_).] [Illustration: Fig. 29 (_c_).] It may be added that children at a particular stage show a preference for some one arrangement; for example, the profile nose and mouth, and the two front-view eyes, which tends to become the habitual form used, though a certain amount of variation is observable. The differences noticeable among different children’s drawings suggest that all of them do not go through the same stages. Thus some may pass by the two-eyed profile stage altogether, or very soon rise above it, whereas others may linger in it.[263] ----- Footnote 263: Ricci says that seventy per cent. insert two eyes in their first profile drawings (_op. cit._, p. 17). But this seems a rather loose statement. ----- [Illustration: Fig. 30.] One notices, too, curious divergences with respect to the mixture of incompatible features. Differences in the degree of intelligence show themselves here also. Thus in one case a child, throughout whose drawings a certain feeble-mindedness seems to betray itself, actually went so far as to introduce the double nose without having the excuse of the two eyes (Fig. 30). In such odd ways do the tricks of habit assert themselves. [Illustration: Fig. 31 (a).] The difficulty which the child feels in these profile representations is seen in the odd positions given to the eyes. These are apt to be pushed very high up, to be placed one above the other, and, what is more significant, to be put far apart and close to the line of contour (see above, Fig. 29 (_a_)). In the following drawing by a boy of five one of the eyes may be said to be on this line (Fig 31 (_a_)). In General Pitt-Rivers’ collection we find a still more striking instance of this in a drawing by a boy of eleven, the second eye appearing to be intentionally put outside the contour, as if to suggest that we must look round to the other side of the facial disc in order to see it (Fig. 31 (_b_)). Curious variations of treatment appear, as in inserting two eyes between the same pair of curves as in Fig. 20 (_b_), p. 350, and in enclosing two pairs of dots or small circles in two larger circles as in Figs. 14 (_b_), and 22 (_a_), pp. 346, 352 (both by the same boy).[264] ----- Footnote 264: I assume that these are intended for two eyes; but the scheme is not easy to interpret. ----- [Illustration: Fig. 31 (_b_).]
