165. We next consider the 

 No. 2 — (Eight) Posterior Line Leading. 



Forcing B b'^ 



The first action felt is 

 in the secondary sec- 

 tion of the (right) pos- 

 terior line, which is 

 that of the (right) true 

 ribs, forcing their move- 

 ment and pressing to 

 the (left) as they turn 

 outward and back- 

 ward ;* but the first 

 result is reflexion, i. e., 

 the lower ribs equalize 

 their inner bearings, 

 from the action in the 

 secondary section. The 

 true ribs then equalize, 

 as the secondary sec- 

 tion. 



By the first move- 

 ment the (left) lower 

 false rib cavity is dim- 

 inished ; by the second 

 the (left) upper true 

 rib cavity is prepared 

 for enlargement. 



Eye muscles act as in 

 § 164, same column. 



*To prevent mistakes, we re- 

 peat what was before said, that 

 if, instead of forcing the old line, 

 the forming of the alternate pos- 

 terior line lead the action, this 

 movement is forward. 



Forcing B b^ 



The forcing of the pos- 

 terior line next brings 

 about an equalization 

 of the posterior cross- 

 line ends, 8o far as pos- 

 sible; but from the dis- 

 placed (" left-right "> 

 anterior end (§ 32) 

 holding its correspond- 

 ing posterior end from' 

 its movement to the 

 (right), this equaliza- 

 tion is performed with 

 a decided " list " to the 

 left, and this remains 

 until the change to an- 

 terior line action liber- 

 ates the displaced 

 (left-right) end. 



The focus of the 

 cross-line end action is 

 always between the up- 

 per and lower lung 

 lobes. 



Eye muscles make 

 their inner bearing 

 equalization at their 

 posterior ends.
