B. Camel. — In this animal, the common supra-spinoua ligament is entirely composed of 

 yellow elasLic tissue; it is therelbre impossible to distinguis.., |)hysically, a dorao-lumbar and a 

 cervical j)orliou. It is remarkable for its tliickness and widtli ; and its dimensions increase 

 from behind to before, especially fr:)m the second lumbar vi rtebra. At the fifth, sixth, seventh, 

 eighth, iiiiitli, and tenth dorsal vertebrje an elastic band is given ofi' from its borders; as this 

 descends, it gmdually becomes tliinnei until it readies tlie external intercostal muscles.

 are placed against the lateral faces of the spinous processes. In the cervical region, the layers

 shaped curve, become inserted into the occipital bone. 



They give oflf, from their inferior bonier, six digitations, which are attached to the spinous 

 processes of the last six cervical verteljrae. An aceessoiy leaf is situated between the two 

 portions just described : it is I'etached from tlie anterior border of the spinous process of the 

 first dorsal vertebra, and is fixed anteriorly into the two last cervical vertebrae.

 this regii>n, does not siiow any cervical ligament, properly so called. It is replaced by a super- 

 ficial fil)rou;j raphe', extending from the occipital bone to the spinous process of the first dorsal 

 vertebra
