Chin. This part of the face, which in Europeans is generally prominent, round and proportioned to the size of the face, in degenerates as in apes is frequently receding, flat, too long or too short.
These anomalies may be studied rapidly with the naked eye, but height, weight, the proportions of the various parts of the body, shape of the skull, etc., should be measured with the aid of special instruments.
Height. Criminals are rarely tall. Like all degenerates, they are under medium height. Imbeciles and idiots are remarkably undersized. The span of the arms, which in normal persons about equals the height, is often disproportionately wide in criminals. The hands are either exaggeratedly large or exaggeratedly small.
