![YORKSHIRE COLLEGE, VICTORIA UNIVERSITY. INTEODUCTION. THE SCOPE AND THE DIVISION OF THE WORK. In the department of pulmonary anatomy, whether normal or morbid, a very Modern large share of study has been devoted, in modern times, to microscojoical chiefly llis- appearances. The extreme periphery of the lung, comprising the bronchioles *^o'°si'^*l- and the air-cells, has been exhaustively investigated. To such an extent has research been concentrated upon them, that attention appears to have been diverted, in the interval, from the imperfection of our knowledge of the anatomy of coarser and less suioerficial structures. In comi^arison with the Compara- tiV6 LlC^lGCt searching description of purely histological details, text-books of anatomy of coarse contain but scanty information concerning the general arrangement of parts ^^^^^o^^y- within the lung. And yet, from a practical standpoint, our most obvious and fundamental importance requirement would seem to be an accurate knowledge of the course followed latter, by the air-tubes and by the pulmonary blood-vessels, and of their mutual and general relations. Without this knowledge neither our a3tiology of the pathological processes, nor our clinical diagnosis and treatment of pulmonary diseases can enter upon a phase of systematic development. In the pathology of the nervous system the greatest advances have been Analogy 1 • jt • • • f T • -I 1 • 1 • 1 111 drawn from made since the investigation of morbid changes within the nerve-cells has ai„itnn]y nf been supplemented by the study of the continuity of the nerve-fibres which establish distant communications between them. Although this analogy can only be argued in a very broad sense, it serves to illustrate by contrast the present stage of our knowledge of the pulmonary structure. Our infoi-raation concerning the terminal structures—viz., the trachea and the air-cells, the heart and the pulmonary capillaries—is fairly complete, and, in some respects, minute; but their connecting links have received only a collective notice. The special object of the present work is to su])ply some part of this Theoigect defect by furthering our knowledge of the individual components of the lung, the work.°^ and especially of the divisions of the bronchi and of the pulmonary blood- vessels.
