Interior Arrangement of Lungs. — On turning this flap over we find a vertical section of lungs, showing their anterior arrangements. The lower end of the trachea divides, one portion going to each long. These again subdividing continue to subdivide in geometrical order, growing smaller and smaller with each division, and extending to every part of the lungs, finally terminating in a cluster of air cells, bound together by cellular tissue and forming a lobule. These lobules vary in size accordingly as they are located on the surface of the lung or deeper in its tissues. Each lobule is separate and distinct from the other, and forms in itself a perfect and independent lung in miniature

Function Of the Lobules. — In this arrangement we see the boundless wisdom of the Creator displayed, for were it not for this wise and perfect; provision — one of the very greatest importance in the process of respiration, since it enables each individual lobule to perform its functions independently of the rest — tubercular disease, bronchitis and inflammation of the lungs would not only be incurable, but would prove to be very rapidly fatal.

The last paragraph of this section is written with very peculiar grammar, some of it seems to be due to its age of a hundred years or more and the rest seems to be bad grammar that slip by the editor, this mixed in with the nonsecular reference makes what would probably be an important statement somewhat obscure.
