5094. The seventh cervical vertebra. 



The costal portions of the transverse process are reduced to an osseous filament, which com- 

 pletes the lower boundary of the vertebral arterial canal. The diapophysis is much longer 

 and thicker than in the sixth. The transverse extent of the centrum continues to increase, 

 as also the antero-posterior breadth of the neurapophyses. The neural spine increases in 

 breadth and slightly in length. 



5095. The first dorsal vertebra. 



The bases of the neurapophyses, instead of being produced forwards, have those angles as 

 it were truncated, to form the articulation with the heads of the first pair of ribs. The 

 breadth of the centrum is augmented, and also, in a more especial degree, that of the diapo- 

 physis, which is excavated below for articulation with the tubercle of the rib. The neural 

 spine is increased in antero-posterior extent, but not in length. 



5096. The second dorsal vertebra. 



The centrum is larger : the anterior zygapophyses are more approximated and distinct from 

 the diapophyses, which thereby appear to be longer : the neural spine is somewhat longer. 



5097. The third dorsal vertebra. 



It differs from the second in the narrower anterior neural emargination, in the somewhat 

 shorter diapophyses, and longer neural spine. The accessory tubercle is more distinct upon 

 the diapophysis. 



5098. The fourth dorsal vertebra. 



In this the neural spine is somewhat broader at its truncated extremity. 



5099. The fifth dorsal vertebra. 



It closely resembles the preceding. 



5100. The sixth dorsal vertebra. 5101. The seventh dorsal vertebra. 



5102. The eighth dorsal vertebra. 



5103. The ninth dorsal vertebra. 



The spinous process is thicker transversely, and more expanded at the summit. The body 

 also presents a more marked increase.
