The rapid expansion of the technic of clinical diagnosis is scarcely appreciated by those who have only recently entered the field of medical practice. To one whose experience ranges over a generation or more, the numerous and notable changes which modern science has introduced often seem little less than revolutionary. Blood chemistry was almost unknown as a diagnostic help only a few years ago; functional tests were among the rarities employed only by the most up-to-date physicians; radiology and electrocardiography were either undiscovered or unapplied. Sometimes the practitioner becomes impatient at the recital of such novelties at his command, and intolerant toward those who recommend the innovation. He avers that the newest devices are passing fads, and that too much attention to the latest test is a waste of time. Let us frankly admit that all too many recommendations of timely helps to diagnosis have failed to meet the expectations accorded to them. Nevertheless, out of the ever growing numbers of tests and procedures, a few always survive to enrich the diagnostic armamentarium of the clinician.
