—Most of the cases of poliomyelitis leading to respiratory involvement begin with paralysis of one or both of the lower extremities. Thirty-five of the thirty-six patients in this series presented an initial weakness of the lower extremities, followed by absent knee jerks and complete flaccidity of these limbs. Several hours later the cremasteric and abdominal
