. A text-book of animal physiology, with introductory chapters on general biology and a full treatment of reproduction ... Physiology, Comparative. - Diagrammatic representation of action of diaphragm in inspiration (Her- mann), Vertical section through second rib on right side. The broken and dotted lines show the amount of the descent of the diaphragm in ordinary and in deep Inspira- Fig. 302.—Apparatus to illustrate relations of intra-thoracic and external pressiu-es {after Beaunis). A glass bell-jar is provided with a light stopper, through which passes a branch- ing glass tube fitted with a pair of elastic bags representing lungs. The bottom of the jar is closed by rubber membrane representing diaphragm. A mercury manometer indicates the difference in pressure within and without the bell-jar. In left-hand figure it will be seen that these pressures are equal; in right (inspiration), the external pressure is consid- erably greater. At one part (6) an elastic membrane fills a hole in jar, representing an intercostal Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Mills, Wesley, 1847-1915.
