Many of the older "wild men" were individuals bearing extensive hairy moles.
Rayer remarks that he has seen a young man of sixteen who exhibited himself to the public under the name of a new species of wild man whose breast and back were covered with light brown hair of considerable length.
The surface upon which it grew was of a brownish hue, different from the color of the surrounding integument.

Almost the whole of the right arm was covered in the same manner.

On the lower extremity several tufts of hair were observed implanted upon brown spots from seven to eight lines in diameter symmetrically disposed upon both legs.

The hair was brown, of the same color as that of the head.

Bichat informs us that he saw at Paris an unfortunate man who from his birth was afflicted with a hairy covering of his face like that of a wild boar, and he adds that the stories which were current among the vulgar of individuals with a boar's head, wolf's head, etc., undoubtedly referred to cases in which the face was covered to a greater or less degree with hair.
