The remarkable accomplishments of medical science during the last few decades may be looked upon as a fairly accurate index of modern progress in general. Nor have these advances been confined to any limited field. Standards of education have changed with almost startling rapidity. The most extended course of instruction open to medical students fifty or sixty years ago covered a period of two years. Qualifications for entrance consisted in little more than a demonstration of the candidate's ability to pay the required matriculation fee. The three year course, only recently established and generally recognized, was lengthened to four years during the latter part of the nineteenth century. The number of medical colleges has been materially reduced and the size of the graduating classes has decreased fifty per cent or more during the last twenty-five years as a result of the higher standards. Several of our medical schools admit college graduates only and two years of college work is now a minimum entrance requirement in institutions of the highest type. Very few men feel properly equipped for taking up the practice of medicine today until they have had an experience of at least a year in a general hospital. The profession is tending more and more towards specialization and the old-fashioned general practitioner is now at a considerable disadvantage. Ophthalmology has become almost an exact science. Gynecologists, obstetricians, pediatrists, orthopedists, laryngologists, neurologists and internists are looked upon as almost indispensable in a community of any size. All of these specialists are more or less dependent on the cooperation of a pathologist, who can do nothing without a well equipped laboratory at his disposal. Surgery has long been regarded as a specialty which required an extended training as well as years of experience.
