As to the full, I conceive the motion of the Thorax fideways, is p61" formed by one right, and one oblique afcendent Mufcle, which beingin conjunélion with one of the Mgfmlz‘ @adrati, do aét jointly. Firft, The left Mufixilur andmtm, maketh a flexure of the Loins out« ward, which is allified by the left oblique afcendent, and right Mulclc, which being joined to the Enfiforin Cartilage, and infide do pull them in their contraction toward the 0f Ilium, and of the left Rib, draws the Thorax toward the left fide. Asto the rotation of the Thorax, which if properly f0 fiiled, fliould be 21 Circular Motion, but this of the Thorax doth run round but one P3": of a Circle, and movcth the Breal't upon the Vertebres of the Loins, as upon a Center. " Again, 7796 Iii/loo: of the Mir/clot. 97 Again, If the motion of the Thorax be truly denomi nated a Rotation, ffhfhc‘fiaggi it is rcquifite it {hould be carried round like 3 Wheel; but this motion of isinorrruli‘ 15> the Thorax, is a hurrying of the Thorax backward, and forward, and is ifiiciloiiiiiic Perfor med if it begin in the left 'fide by the left oblique defcen and the 2:533:22: right afcendent Mufcle; and if it commence in the right fide,dent, by the right; EILkbuatznlyd oblique defccndcnr, and the left afcendent Mufcle, as learne d Doélor Gliflim rdfwiiii. " will have it: which motion doth not feem to comply with the Struéture and Situation of theft: Mufcles. The oblique defcendent being fallned above, to the Four or Five JOWer Ribs, which being the Center of Mo" tion, the 0! Ilium, to which it is fallned below, mull iiecelf arily be draWn obliquely upward, toward the Center of the Motion, by i-eafon of the oblique defcendent Fibres of the End Mufcle. ' And the oblique afccndent Mufclc being tied above to the infide of the fpurious Ribs, and below to the 0f Ilium (which being immoveable) the {aid bdufcle moving by its oblique afcending Fibres, mull by confequence pull the long Ribs downWard toward the ()r Ilium, as a Hypom oclion. So that according to the Origen and InlErtion of thefe Mufcles, and the Politico of their oblique Fibres conflituting them, the oblique delcendent and alcendent, ‘ according ‘ to their' various ‘ Centers of Motion, do draw the 0r Ilium and Ribs, obliquely upward and downw ard; which are oppofite motions to that of Rotation, becaufe this motion of the Brealt is performed in fome degree backward and forward, not by oblique motion of the $5933?un Hn m: sciiicjczoiriéi M ll t and aftendcnt gtggggfigy Pfifi'loglliabdo llitmrarilkribs oblique defcendent and afcendent Mufcles, pulling their neighbouring Parts 33:3"le qu upward and downward. downward, But the Rotation of the Thorax is performed forwa rd and backward, inward and outward: Firf't, Inward by the motion of the Loins primarily, and confequently of the Breafl by the Mtfmlm Qyzalrz rtnr, moving in one 2355:3313, {ide bendeth the Vertebres of the Lorns, and drawe th it inward, and is af- Siggvgfl" filled by the Tranfverfe Mulcl e of the lame fide, which is affixed in its tergit, egnrrai xiii-nation to the Lima Alba, as its Hypomoclio n, and in its beginning to the fitlh‘lc‘s: (:21tranfverfe procclles of the Loins, near which the Tranfverfe Mufcle, by "mm" vertlie of its contra cted Fibres, firf't pulleth the Loins and Thorax _ inward, L°i"""wa "‘_ toward the Lima Alba: And afterward a tenfion being and alto backmade upon the ward,accordVer‘ ‘ . . . ~ . d' tcbres or the LOins, by one of the Mlfl‘ull Sarrz, the Rotation of the Louis ccntcrsofma"gm ""5 and Thorax backward, is allil'ted by the Tranfverfe Mufcle of the fame ‘i‘m' fide, which being conjoyned to the tranfverfe precedes of the Loins, as the Center of Motion, and in the other extreamity to the Lima Alba, as a nioveable term, the Motion is celebrated near it, by of the faid Mufcle; which retraétcth the Loins and the tranfverfe Fibres Thorax backward, by moving the Linea Alba outward toward the [oins But, I humbly conceive, the faid Rotation of the Loins and Thorax, "mum, begun by the didrattw, Sacer, and Tranfverfe Mufcle. is very much pro. gfélfh'aii‘f meted by the Mufcles of the Thigh, which being lifted up by the Pfoas, and bigun byth‘c Iliacur brim/m", is carried inward and forward by the I ividus, and Tric 6 S, drum, mm Q"and and draweth with it the l oins and Thorax much farther, than they wePie fiflififim carried by the Flexor of the Loins, and the Tranfverfe Mufcle of the Belly; 31:31:? and afterward the Rotation of the Loins and Thorax made outwar . ,. iS‘and "I'm" . .
