[N'o. 1— (Left) Anterioe Line Leading. 



Forcing A a^. 



Equalizes* lower (right) 

 false ribs with (left) 

 ones on outer bearings. 



Fills (right) lower 

 lung lobe.t 



Anterior portion of 

 (left) eye muscle turns 

 outward equalizing 



with the analogous 

 portion of the right eye 

 muscle. 



*When the word equalize is 

 used, it denotes "so far as the 

 movement in question will carry 

 it." The final movement is nec- 

 essary to complete any part. 



t The lung lobes draw from 

 each other collaterally— thus, the 

 right lower lobe draws from the 

 right ui)per; the left upper from 

 the right lower. 



Forcing A a'^ 



(Eight) upper C (true 

 rib) cavity reduced. 



''Left -right" and 

 ' * right-left ' ' anterior 

 cross-line ends (§ 20) 

 equalized with the left- 

 right as to position 

 (both come to centre). 

 This takes effect be- 

 tween the upper and 

 lower lung lobes, re- 

 ducing the right upper 

 lung lobe from its pos- 

 terior part. 



Posterior portions of 

 eye muscles equalize on 

 outer bearings.
