Nitrous oxide may also he used advan* tageously for sliort operations on the aged.” Murphy’s warning is timely and his conclusions coincide with the author’s experience. However, after performing operations upon dogs that had been given preliminary injections of chlore- tone at the Parke, Davis & Co. laboratories, and ob.serving the growing tendency to recognize the value of morphine, .scopolamine and morphine, and similar preparatory drugs, the author believes that future advances will undoubtedly be in the direction of greater use of these and similar preparations. For this reason he feels that a discussion of the subject would be incomplete without citing the following conclusions of George W. Crile, of Cleveland, based upon recent research. He presents a vast amount of clinical, animal, experimental, and other scientific evidence in support of his statements, for which the reader is referred to the original articled “The word anesthesia—meaning -withont feeling—describes accurately the effect of ether in anesthetic dosage. Although no pain is felt in operations under inhalation anesthesia, the nerve impulses set up by a surgical operation still reach the brain. We know that not every portion of the brain is fully anesthetized, since surgical anesthesia does not kill. The question then is, What effect has trauma under surgical anesthesia upon the part of the brain that remains awake? “In response to an adequate stimulus, the nervous system is integrated for the specific purpose of the stimulated receptor, and but one stimulus at a time has possession of the final common path—the nerve mechanism for action. The most numerous receptors are those for harmful contact. These are the nociceptors. “In case of a surgical operation, if fear be excluded and if the nerve paths between the field of operation and the brain be blocked with cocaine, there will be no discharge of energy due to the oper- ation; hence there can be no shock, no exhaustion. Under these conditions of operation the nervous system is protected against noci-association, whether by noci-])erce])tion or by an adequate stimulation of nociceptors. The state of the ])atient in whom all
