ends exchange for collateral actions, between the 

 upper and lower lung lobes, as primary section 

 action. The changes caused in the lines of gravity 

 give this fundamental movement a general effect 

 throughout the body. 



Composite Spine. — The lower lung lobes go on 

 filling and the hip-joints interchange outer-bear- 

 ings for the secondary section. Then the small 

 of the back and the upper corners of the sternum 

 adjust their right and left sides, as continuing the 

 action of the anterior cross-hne ends for the prim- 

 ary section. 



Bicomposite Spine. — The lower lung lobes con- 

 tinuing to fill, the hinder hmbs adjust themselves 

 for the secondary section, the lines passing in rear 

 of the hip joints. Then, the lower jaw articula- 

 tions adjusting on the outer bearings, followed by 

 the rotary movement of the head condyles, on 

 their rear ends, and the forward across-joint move- 

 ment of the condyles, followed by the adjustment 

 of the shoulder-blades on the outer bearings, rep- 

 resent the anterior cross-line ends in the 2y'''iMary 

 section.* 



♦The movement between the lower jaw articulations and shoulder- 

 blades, crossing at the junction of the neck C, is as if th3 body swung 

 between them, as the bicomposite tractions confirm those which have
