The great progress which medicine in general has made during recent years, must in considerable part be ascribed to the anatomical direction it has assumed. The study of pathological anatomy has entirely changed the character of medical science, which, instead of a chaotic medly of unfounded theories and ingenious hypotheses, the fruits of speculation, is now a philosophic system resting on a firm foundation of facts with mutual and definite relations. To such an extent has the pathological investigation of disease been carried, that, in the ordinary maladies which attack the body, the instances are now exceptional where we cannot demonstrate certain gross, palpable changes of structure having an invariable causal connection with functional disturbance. By bringing diagnostics to our aid, we can also in many cases predict with confidence and precision the nature and extent of the lesion which will be found after death. But the triumph does not cease here. In conjunction with chemistry and the microscope, pathological anatomy has passed from the gross alterations of organs, and succeeded in elucidating the processes and changes which take place in their ultimate elements; and Virchow, bringing to the subject all the zeal and instinct of genius, has given us an insight into the arcana of cell-life, and laid down the comprehensive generalisation as the basis of a new pathology, that the cell is the ultimate agent by which, both in health and disease, structural and functional alterations are effected. All the practical departments of the healing art have participated more or less in this progress. Medicine proper, or that branch which restricts itself to the study of internal diseases, has separated itself more and more from dynamics, and found a natural explanation of its symptomatology in anterior changes of structure; while surgery and mid-wifery, with their outbranching specialities, are daily becoming more anatomical in character.
