iik Iii the Spermaceti Whale, the Bottle- 

 ainpus. and the Porpoise, the lower 

 . especially at the posterior ends, resemble 

 - other; hut in hotli the lar^e and small 

 U halcbonc Whales, the shape differs c 

 ahly: the number of some particular hones like- 

 wise differs very much. 



The Piked Whale has seven vertebra; in the 

 neck, twelve which may be reckoned to the back, 

 and twenty-seven to the tail, making forty-six in 

 the whole. 



In the Porpoise there are five cervical vertebrae, 

 and one common to the neck and back, tour 

 proper to the back, and thirty to the tail, ma; 

 in the whole fifty-one. 



The small 15ottle-no.se Whale, in the number of 

 cervical vertebra?, resembles the Porpoise ; it has 

 seventeen in the hack, and thirty-seven in the 

 tail, in all sixty. 



In the Porpoise, four of the vertebrae of the 

 neck arc anchylosed ; and in every animal of this 

 order, which I have examined, the atlas is by 

 much the thickest, and seems to be made up of 

 two joined together, for the second cervical nerve 

 posses through a foramen in this vertebra. There 

 is no articulation for a rotator}' motion between 

 the first and second vertebrae of the neck. 



The small Bottle-nose Whale has eighteen ribs 

 on each side ; the Porpoise sixteen. The ends of 

 the ribs that have two articulations, in the whole 

 of this tribe, I believe, are articulated with the 

 body of the vertebne above, and with the trmna-
