The parents and brothers were healthy and possessed a full growth of hair.

Thurman reports a case of a man of fifty-eight, who was almost devoid of hair all his life and possessed only four teeth.

His skin was very delicate and there was absence of sensible perspiration and tears.

The skin was peculiar in thinness, softness, and absence of pigmentation.

The hair on the crown of the head and back was very fine, short, and soft, and not more in quantity than that of an infant of three months.
