At the further extremity of the horizontal lines will be found the figures recording the number of times that any one anomaly occurs in a hundred instances. The other indications are explained in the figure itself.
From this it is apparent that anomalies of the cranium are much more rare than those of the face, both in children and in adults.
But in children the anomalies of the cranium (and this includes the cases of plagiocephaly), are much more frequent than in adults in all social classes; this shows that in the course of growth the malformations of the cranium have to a great extent disappeared.
In regard to the face, on the contrary, or, at least, in regard to certain malformations of the face, the opposite holds good; the mandible and the zygomata, or, in general, that part of the face which grows rapidly during the period of puberty, show more anomalies in the case of adults than in the case of children.
This shows us that a face which is still beautiful in childhood may acquire malformations in successive periods of growth. In simpler words, the facts may be expressed as follows: that the cranium corrects itself and the face spoils itself in the course of growth.
But in the case of facial asymmetries the same thing occurs that we have already seen in regard to plagiocephaly; it is more frequent in children, hence asymmetries are infantile stigmata.
Fig. 139.—Two small examples of Morel's and Wildermuth's ear.
Some important characteristics are to be noted regarding the handle-shaped ear; all children have ears proportionally larger than those of adults and the handle-shaped form is very frequent in normal children, regardless of the social condition to which they belong. This malformation corrects itself in the course of growth, being far less frequent in adults of the wealthy class and even among the labouring classes; but among the peasantry it remains permanently, almost as though it were a class stigma. Although the mechanical theories are in disrepute as an interpretation of morphological phenomena, nevertheless it is worth while to note the singular frequency of this stigma in peasants, in connection with the habit of straining the ear to catch the faintest sounds, distant voices, echoes, etc., for which the senses of peasants are extremely acute.
