Drs. Paul and Josias used oxygen in this malady, and, although the patients died, some relief was given to the symptoms of asphyxia. Recently Dr. Schmidt has recorded the case of a girl, aged twelve, who, when recovering from diphtheria, was bitten by a mad dog; seventeen days afterward she had difficulty of breathing and of swallowing, and oxygen-inhalation relieved her; she relapsed next day with convulsions, spasms of respiratory muscles, and unconsciousness; oxygen again relieved her, and, after some complications traceable to the diphtheria, she ultimately recovered (Medical Record, 1878).
