On the "Pointed Ear" in the Human Species. In' Virckovi's Archiv., B. LIII., Th. IV., Professor L. Meyer, of Gottingen, criticises the assumption that the pointed ear in man is a relic of a lower species. Headers may remember that in Darwin's book on the " Descent of Man" there is a paragraph, illustrated by a woodeut, in which he asserts that certain processes, which occasionally occur in the ears of men, are of a similar nature to the points in the ears of apes. These pointed processes are situated on the anterior margin of the helix, near its upper part. The author of the present paper points out, however, that in most human ears there are irregularities in the development of the helix, especially at this part. In some cases the helix is almost entirely wanting, in some there are greater or smaller gaps in it, and what Darwin looks on as points or processes, are really produced not by an outgrowth from the helix, but by gaps existing on each side of the apparent process. A case is given where the helix was absent, but at intervals there were small knobs, three in number, which were all that represented the rudimentary helix. It is therefore concluded that Darwin's pointed ear is no indication of a return to the ape-like form. Histology and Physiology of the Penis.
