and are always connected with the head condyle 

 movements, whether these be superficial to accom- 

 modate the turnings which ascend the neck from 

 the ophidian and composite spines, or thorough to 

 accompany the formation of the bicomposite 

 spine. 



The secondary sections of the anterior lines af- 

 fect the anterior part of the eye muscles and di- 

 gastrics with an outward turn ; the primary, the 

 posterior part in a similar way. 



It is in displacing or equalizing the positions of 

 the anterior cross-line ends that the primary sec- 

 tion motion more particularly manifests itself. 



The anterior Knes give outward bearings on the 

 convexe§, the posterior lines give inward bearings 

 on the convexes^ but on the concaves they give out- 

 ward T3earings. Thus, when the alternate left 

 upper lung lobe is filled in equalizing, it is with an 

 outer bearing of the lower (left) true ribs, being in 

 the secondary section equalization of the left post 

 point of apphcation. 



Second. — The posterior lines would develope in 

 a manner similar to that of the anterior lines, viz. : 

 first, and more especially, in the front C C C, as 

 the anterior do in the rear C C C, and end by 

 moving the posterior cross-line ends, were it not
