Paralysis of the adductor of the thumb is extremely common. Abdominal paralysis existed in more than half of all the cases (seventy- nine), and affection of the muscles of the spine in more than a quarter (forty). The latter points have a distinct bearing on the occurrence of scoliosis, and indicate, apparently, that such affections are more common than had been supposed. The cases of abdominal paralysis were always symmetrical with
