The Diaphragm feems to be acted with a double motion, the Dial'tole ed, and the cavity of the Thorax rendred narrow, when the Diaphragm in its [fate of reflitution is brought unto an Arch, having its upper furfaee, looking toward the Heart Convex, and Concave toward the Stomach and Intefiines, whereby the Lungs are comprefl'ed, and the Stomach and Outs are fer atl'iberty, as afcending upward into the cavity of the '1720rax toward the In the Syfiole, which is the true motion of the Diaphragm, it is preffed the Ribs might be carried outward in their extenfion, made by the mutut contraé'tion of the External and Internal lntercoftal Mufcles, to render the ~ Cavity ofthe Thorax more large in Infpiration ', in which the extremities of t bafiard Ribs, have a contrary pofition, as being drawn inward, in a difl'iclll'l' of breathing, which is caufed by reafon the termination of thefe Ribs are tit to the flelhy circumference of the Diaphragm, which being violently gn‘ tn. 5 ) The Syfiolc is the true mo- downward, and quitteth its arched pofition, and is brought very much toward a Plain, and the Vi/oera of the lOVVCfl‘. Apartiment lodged within its Cancave walls, are beaten downward and outward, whereupon the Cavity tion of the Diaphragm, wherein it is brought to 3 Plain. of the Thorax becometh much enlarged, as acquiring greater dimenflons of length, to entertain the dilated Compage of the Lungs when rendred big with Air. The mofi proper and principal Organ of Refpiration, are the Lungs, as a Machine, in which the Air fporteth it felf in and out in various motions, produélive of Infpiration and Expiration. In the firl't the {tream of Air is received, either through the Nofirils, or immediately through the Mouth into the greater Channel of the Windpipe, and afterward into the Branches of the Brant/aid, as fo many fmallcr Pipes, and from thence into the numerous Membranous Sinw, as f0 many Out-lets of the Bronchia, interfperfing the Lobules with white Interl'tices; whereupon this fine fpungy Compage, made up of different Cylinders and membranous Orbs, groweth highly expanded with thin, fpitituous, and Elaliiclt Particles of Air. In Expiration the Air maketh its retrograde motion out of the Lungs, as thereceptacles of Air are comprefled by the Ribs, Diaphragm, and weight of the Lungs, whereupon the numerous {mall Tubes of Air and their appendant 8mm grow lank, as being leffened alfo by flraight and circular Fibres, contrafiing the Cavities of the fruitful Cylinders and Orbs of Air; f0 that And it may be farther obferved, that the Cartilages of the Ribs, by whole interpofition the Ribs are conjoyned to the Sternon, are inferred into lhe Ribs with an eminent obliquity, which is wifely framed by Nature, that in truth is but one. concave furface of the Midrifl‘: tiumq; in tbomre pro pulmonibm late explimndi: fatir amplum aperiatur.
