. The descent of man, and selection in relation to sex. Evolution; Natural selection; Heredity; Human beings -- Origin. Chap. I.

It has been asserted that the ear of man alone possesses a lobule; but "a rudiment of it is found in the gorilla;"31 and, as I hear from Prof. Preyer, it is not rarely absent in the negro. The celebrated sculptor, Mr. Woolner, informs me of one little peculiarity in the external ear, which he has often observed both in men and women, and of which he perceived the full" signi=» ficance. His attention was first called to the subject whilst at work on his figure of Puck, to which he had given pointed ears. He was thus led to examine the ears of various monkeys, and sub- sequently more carefully those of man. The peculiarity consists in a little blunt point, projecting from the inwardly folded margin, or helix. "When present, it is developed at birth, and, according to Prof. Ludwig Meyer, more frequently in man than in woman. Mr. Woolner made an exact model of one such case, and sent me the accompanying drawing. (Fig. 2.) These points not only project inwards towards the centre of the ear, but often a little outwards from its plane, so as to be visible when the head is viewed from directly in front or behind. They are variable in size, and somewhat in position, standing either a little higher or lower; and they sometimes occur on one ear and not on the other. They are not confined to mankind, for I ob- served a case in one of the spider- monkeys (Ateles beelztbutli) in our Zoological Gardens; and Dr. E. Ray Lankester informs me of another case in a chimpanzee in the gardens at Hamburg. The helix obviously con- sists of the extreme margin of the ear folded inwards; and this folding appears to be in some manner connected with the whole external ear being permanently pressed backwards. In many monkeys, which do not stand high in the order, as baboons
