Fig. [44] illustrates noticeable stigmata. The ear stands at right angles with the head. It is, however, almost as broad as it is long and differs in shape. The outer helix is excessively developed. The scaphoid fossa extends through the lobe, which is continuous with the body of the ear and is not distinct. The root of the helix is excessively developed. There are three Darwinian tubercles on its border. The anti-tragus is undeveloped. The tragus is very small and divided into two parts. The auricle-temporal angle, for functional purposes, should not exceed, according to Buchanan, 30°, or be less than 15°. The difference in this respect is not clear, since free movement of head and body will readily adjust the auricle to receive sound. For functional purposes it would seem that the construction and shape of the ear, especially the anti-helix and concha, would be of greater importance than its position to the head, since it is necessary to collect the waves of sound for transmission. From a degeneracy standpoint, however, the position of the ear is important. Frigerio,[215] from the examination of several hundred subjects, concludes that the auricle-temporal angle undergoes a gradual progress from below 90° in criminals and the insane to above 90° in apes. He found the large angle very marked in homicides, less so in thieves. There is no question but that Frigerio is correct in regard to this point. In an examination of the ears of 465 boy criminals at Pontiac, it was found that 198 were close to the head, or from 10 to 15°; 152 at an angle of 45°, and 115 at right angles or 90°. Of 1,041 criminals at Elmira 285 were close, 567 at an angle of 45°, and 187 at right angles.
