the paper obtained remarkably clear illustration and confirmation. One point of great practical importance indicated by these graphic methods was that in deep narcosis the respiratory heavings of the thoracic walls may go on to all appearance perfectly, and yet absolutely no vapour enter or leave the chest. Dr. Murray considers this condition to be one of respiratory incoordination, the motor coordinating centre being affected, resulting in a " respiratory stammer," in which, although the

As a result of his experience in cases of suspended respiration from the use of chloroform, Dr. Murray strongly insists on the importance of withdrawing the chloroform vapour from the lungs before commencing to introduce pure air. lie advocates the introduction of a tracheal catheter in the human subject in such cases, and the removal by suction of as much of the vapour as possible before inducing artificial inspiration by the ordinary means. In rabbits he found that where this method was adopted resuscitation could be achieved even after a prolonged suspension of respiration, whereas were the ordinary means adopted, a successful issue was rarely attained.
