454 Z)/\ Camper’s ConjeBures relative to the 
Marcgraf, Hift. Braf. p. 236. cap. n.; but I found no 
fuch divifions, though the animal was young, and though it 
had ft ill epiphyfeson the legs, &c, The neck co n fids of 4 verte- 
brae, the back of it, the loins of 9, the os facrum of 2, as: 
in the crocodile ; the tail of more than 60. 
The diffeftion of tortoifes feemed to me of confequeuce, at: 
lead a more accurate infpeftion of the vertebrae, particularly 
thofe of the neck, as being analogous in feme refpeds to 
thofe of the crocodile, efpecially in the ftrudure of the infe- 
rior precedes D* and E, with /, fig. 1.

Thofe bony lamellae are the epiphyfes of the vertebrae, and 
are alike in all quadrupeds, to which clafs all the cetaceous 
fi flies belong. When we confider the ftrudure in general 
of thefe lad, we find the hind legs only are wanting, and of 
courfe the offa innominata ; but the offa pubis are very re- 
markable in all of them-
