the (right and left) upper corners of the sternum. - 

 Continuing the drawing will equalize the whole. 



Second. — With the (left; eye muscle turning in- 

 ward, first, in its rear portion, by reflected action ; 

 lastly, in its anterior portion, by proper action, al- 

 low the alternate (left) posterior winding-line to 

 form for the secondary sections, viz., by bringing 

 the inner bearing on the (right) false ribs, which 

 implies a reduction of the cavity under the (left) 

 false ribs (§ 39 and note), by taking the inner 

 bearing from the (left) hip joint to the (right) ; by 

 filhng the (left) upper lung lobe from below as the 

 lower (left) true ribs turn outward. Then for the 

 primary section, the drawing of the alternate ante- 

 rior (right-left) cross-line end will bring the alter- 

 nate posterior (left-right) end into action ; discharg- 

 ing the old point between the lung lobes ; at the 

 small of the back ; and at the lower end of the 

 sternum. 



Third. — From the bicomposite alternate (right) 

 anterior Ime, first, on the right lower jaw articula- 

 tion, then on the left shoulder blade, discharging 

 the old fine — equalize. Then the bicomposite 

 alternate (left) posterior line, on the left shoulder 



* It is often necessary to equalize somewhat the small of the back and 

 corners of the sternum before the movement between tlie lung lobes 

 can be effected.
