Fabricius Hildanus saw a patient with horns all over the body and another with horns on the forehead.
Gastaher speaks of a horn from the left temple; Zacutus Lusitanus saw a horn from the heel; Wroe, one of considerable length from the scapula; Cosnard, one from the bregma; the Ephemerides, from the foot; Borellus, from the face and foot, and Ash, horns all over the body.

Home, Cooper, and Treves have collected examples of horns, and there is one 11 inches long and 2 1/2 in circumference in a London museum.

Lozes collected reports of 71 cases of horns,--37 in females, 31 in males, and three in infants.

Of this number, 15 were on the head, eight on the face, 18 on the lower extremities, eight on the trunk, and three on the glans penis.

Wilson collected reports of 90 cases,--44 females, 39 males, the sex not being mentioned in the remainder.
