Surfaces. In each and all of each of these different <s>structures the<\s> portions of the lungs, the shape which they present consists of three distinct surfaces, clearly defined by margins more or lass acute. They exhibit, first an upper and somewhat convex surface in which the capil= =lary blood-vessels, principally in connection with the pulmonary artery are seen; next an inner or flat surface forming the interlobular surface and which in the aggregate corresponds with that portion of the lungs, which lies in contact with the peri= =cardium; and thirdly the under surface, which is rather concave than otherwise and is that portion <s>of the lungs<\s> which lies upon the other leaflets or lobules and coincides in the aggregate with that portion of the lungs, which lies upon the diaphragm. A transverse section of each <s>lung<\s> leaflet therefore is some= =what triangular in form, and the space included between the <s>leaflets<\s> surfaces of each leaflet is filled up with a spongy tissue, and the name of aircells is usually given to the interstices within it - Each group of lobules, each lobule and each leaflet may therefore as far as these particulars go be looked upon as a diminutive but perfect lung - The capillaries belonging to the two surfaces last men=
