outermost point of the lower edge of the ribs and 

 gives the greatest capacity to the chest. 



The filling of the upper C of a lung tip is con- 

 nected with the formation of the upper part of the 

 composite spine in the anterior winding-Une. It. 

 thus accompanies the turn outward from the lower 

 part of the collateral stemo-mastoid and of the 

 diagonal diaphragm pillar and psoas. The filling 

 of lower C is connected with the formation of the 

 lower part of the composite spine in the posterior 

 line, and thus accompanies the turn inward of 

 those muscles from their upper parts. 



§ 130. The fore-limbs we suppose to be guided 

 by the anterior part of the trunk, and by the neck,: 

 in the following manner. The edge of the shoul- 

 der blade, opposite to the arm socket, or more 

 exactly speaking, that perpendicular to the prolon- 

 gation of the central axis of the movements of the 

 anterior limb* lies on the posterior true ribs, near 

 the spine, so as to be guided by the propellers of 

 their convex (§ 62), and thus follows their move- 

 ments. 



* This would not include the "whole of the posterior part of the shoul- 

 der blade, some portion being under the guidance of the neck. Refer- 

 ring to the beat engravings to which we have access, there is a diflfer- 

 ence in the proportion of the shoulder blade, which might be supposed 

 to be guided by these ribs ; the part under the influence of the neck be- 

 ing much larger in the lion than in the horse and giraffe.
