There is no more reason why we should adhere to the drop method of chloroform or the cone method of ether when a better and more exact method is produced than that we should continue to use the "one horse shay" when the automobile is available. Nor is it sensible to continue the foolish custom of allowing the most inexperienced interne to narcotize instead of having a professional anesthetist in every hospital.
Furthermore, because a man has given an anesthetic many times during his hospital service and irregularly afterward, it is no evidence of his ability to do the same thing several years after, with even a reasonable degree of success. The wonderful advancement in all departments of medicine has come from men devoting their exclusive time to some one branch of it, and especially is this true of anesthetics. We are indebted to England, where the professional anesthetist prevails
