pressed, the lower lungs are exhausted ; the muscles 

 passing from the lower end of the sternum to the 

 pubis adjust themselves so that the lines of gravity 

 of the body come upon the inner sides of the feet 

 (reaction). The upper ribs being raised by their 

 interchange of inner bearings at their articulations 

 are filled (proper action). This for secondary sec- 

 tion. For primary section, the axial line of filling 

 for the upper lung lobes passes through the lower 

 end of the sternum, at which, and following it, at 

 the small of the back, the posterior cross-line ends 

 adjust themselves on either side. Then the poste- 

 rior points of application on each side at the ante- 

 rior points of the pelvis."^ 



Bicomposite spine. — The hinder limbs inter- 

 change inner bearing (reaction). The shoulder- 

 blades do the same (proper action) secondary 

 section. The movement on the anterior ends of 

 the head joint sockets followed by their movement 

 backward on the outer edges of the head condyle, 

 which changes the lines of general thrust and 

 brings the bearing on the lower jaw, as represent- 

 ing the cross-line ends. Finally, the adjustment of 

 the posterior points of application at the hip-joints 



* At every stage more and more appui has been taken on the shoulder- 

 blades.
