nection presently to be described. At the head it 

 is received and adjusted with the action of the 

 true ribs of the other side. 



It is possible that we ought to assign one or two 

 of the true ribs to the rear C of the spinal curve ; but 

 the proportionately greater length of that portion of 

 the spine to which the false ribs are attached, and 

 the fact that the first — or first two — upper ribs"^ 

 seem rather to belong to the joint of the root of 

 the neck (§ 90) and the spine than to the front C, 

 might give sufficient preponderance of force as 

 propellers to the false ribs alone (§ 62). This 

 being the case, toe have adopted the more convenient 

 nomenclature of assigning all the true ribs to the an- 

 terior C, and all the false ribs to the ijosterior one. 



§ 83. If we give an artificial ground to the ribs, 

 one S in the spine will be required to work on it ; 

 if we attach two rear appui to the trunk thus 

 formed, another S will be required for their sup- 

 port ; and if the whole is to be centred on the 

 head, still another S will be required for combin- 

 ing the two first, and this last S will require some 

 separate appui on which to effect this combination. 



These requirements, we think, are fulfilled in 



* These ribs, we believe, are bent from front to lear in a different 

 tlircction from the other true ribs.
