2559. The first dorsal vertebra. 



The lateral part of the centrum bears two articular facets ; one of which is smaller than the 

 other, looks forward, and receives a part of the head of that rib which articulates with the 

 preceding vertebra ; the other looks backwards, and receives a large share of the head of the 

 second dorsal rib. The transverse processes are long and strong, and present on their ex- 

 tremity an articular facet which receives the tubercle of the first free or dorsal rib. 



2560. The second dorsal vertebra. 2561. The third dorsal vertebra. 



2562. The fourth dorsal vertebra. 



2563. The fifth and sixth dorsal vertebrae. 



Anchylosis has united the extremities of the neural spines of these two vertebrae. 



2564. The seventh dorsal vertebra. 2565. The eighth dorsal vertebra. 

 2566. The ninth dorsal vertebra. 2567. The tenth dorsal vertebra. 

 2568. The eleventh dorsal vertebra. 2569. The twelfth dorsal vertebra. 

 2570. The thirteenth dorsal vertebra. 2571. The fourteenth dorsal vertebra. 

 2572. The fifteenth dorsal vertebra. 2573. The sixteenth dorsal vertebra. 



2574. The seventeenth dorsal vertebra. 



2575. The eighteenth dorsal vertebra. 



The rib has here a single articulation, viz. with the slightly raised transverse process. 



2576. The first lumbar, or twenty-sixth trunk, vertebra. 



This, and most of the succeeding vertebrae, have the ribs anchylosed to form long trans- 

 verse processes. 



2577. The second lumbar vertebra. 2578. The third lumbar vertebra.
