4923. The axis. 



4924. The five succeeding cervical vertebrae. 



The transverse processes of the seventh are grooved, but not perforated, by the vertebral 

 artery. The simple spines progressively increase in length. 



4925. Twelve dorsal vertebrae. 



In these may be remarked the gradual change of position in the metapophysis, and the 

 corresponding change of direction of the zygapophyses, in the last three vertebrae. The 

 diapophysis is retained, together with the anapophysis in each vertebra. 



4926. The six lumbar vertebras. 



4927. The sacrum. 



It consists of three vertebrae. The articular surface for the iliac bones is formed of the 

 first two. 



4928. Four proximal caudal vertebrae. 4929. Ten distal caudal vertebrae. 



4930. The first pair of ribs. 



The great length of the cervix and large size of the tubercle are worthy of notice. 



4931. The second pair of ribs. 4932. The third pair of ribs. 

 4933. The fourth pair of ribs. 4934. The fifth pair of ribs. 

 4935. The sixth pair of ribs. 4936. The seventh pair of ribs. 

 4937. The eighth pair of ribs. 4938. The ninth pair of ribs. 



4939. The tenth pair of ribs. 



The junction of the cervix with the shaft is now becoming less angular. 



4940. The eleventh pair of ribs. 4941. The twelfth pair of ribs.
