Difficulties of Diagnosis
Many times a diagnosis is impossible simply because the symptoms and signs have not advanced sufficiently to furnish adequate basis for diagnosis. Practically all the importantdiseases can be diagnosed accurately only when there are fairly - pronounced indications. Certainly one should not postpone treatment until these indications do become sufficiently prom¬inent for a diagnosis to be made easily. Nor should one be content merely with treating to allay, or with allaying the symptoms. He should wish and aim so to reach the underlying causes as to check the developing disease and as nearly as possible restore normality.
