TABLE 



OF DIMENSIONS OF THE V BONES IN SYDNEY SPERM WHALE. 



OF THE RIBS. 



The somewhat cuxular chest, on account of the disappearance 

 of the neck, appears close to the posterior part of the head. The 

 first, ninth, and tenth pairs of ribs have only one articulating 

 surface to their proper vertebrae, but the second, third, and 

 fourth, have two articulating surfaces, and the fifth, sixth, 

 seventh, and eighth, have three. The ribs on the left 

 side are of larger dimensions than the corresponding ones on 

 the right, as the following table will show.
