fering from thofe in Man, which are joined with the 

 Shoulder. They help to fuppcrt the Shoulder-blades, and 

 keep them from Aiding forward upon the Breall-bone and 

 Shoulder-bones, which, upon a Fradlurc, or Diflocaiion 

 of ihefe Bones, frequently happens. 

 Th R'b Next the Collar-bones arc feated the 



Ribs. They are in all thirty four, viz. fe- 

 venteen on each fide. Their Subftance is partly bony, and 

 partly cartilaginous. The nine uppermoft are called the 

 true Ribs, becaufe each, with its Fellow, makes a Kind of 

 Circle, being joined together by the Mediation of the Rack- 

 bones of the Back behind, and the Breall-bone before ; 

 each Rib has two Knobs, one of which is received into the 

 Sinus of the Body of the Vertebra, and the leiler Knob 

 into that of the tranlVerfe Procefs ; they are in like manner 

 joined to the Breaft-bone, their Cartilages ending in little 

 iieads, which are received into its fmooth Sinus's. 



The eight lowermoft are call'd the Bajiard-ribs, becaufe 

 they don't circumfcribe tHe Body, as the uppermoft do, 

 by their twofold Articulation into the Rack-bone, and 

 Breaft-bone. They are of a more foft and pliable Sub- 

 Itance than the true Ribs, and the nearer they advance to- 

 wards the Loins, they grow fhorter, leaving an open Space 

 for the Stomach and Guts, which might have eafily beeii 

 hurt by them, as often as diftended with Meat and Water. 



They arc all rough and uneven on their Outfide, efpecial- 

 \j towards the Back, that the Ligaments, by which they 

 are tied to the Rack- bones, might take the firmer Hold ; 

 but on their Infide they are i'mooth, and covered with the 

 Pleuru, left they ftiould hurt the Lungs, and the other 

 Parts that bear again ft them. They are alfo narrow and 

 thick towards the Back, but broader and Hatter towards 

 the Breaft, and are fufrowed on the lower Part of their 

 Infide, in which fome Blood-vefiels and a Nerve are con- 

 duced. They are a Defence to the Rowels within the 

 ^leaft, and likewife to thofe in the lower Belly.
