peels ; notwithstanding the Tradition of his moving the 
upper Jaw. 
The Teeth are about threefcore, thirty in each Jaw. 
All of them Clavkulares, or Peg-Teeth, not much unlike 
the Tusks of a MaftifF 3 and fcarce bigger : notwithftand- 
ing that Ariftotle calls them great Teeth, ^Av*. (a) {*) 
And yet, whereas a Dog hath but four Tusks, or exerted * 
Teeth,in this Animal being all of that %ure,their fmallnefs, 
with refpecl to fo great a Head, is fully compenfated by 
their number. For the moft part, thofe that are new 
and not worn, are toothed, like a fmall Saw, on their 
fides. 
The Vertebra,- in all, fixty. Thofe of the Neck,are feven, 
as in a Man. The firft whereof, in a Man called the At- 
las, hath a Procefus in the figure of the Epiglottis. The 
other fix, have each one Procefus or Prominent Part, which 
is long, broad, lharp, and upright : and two that are tranf- 
verfe, and Ihort 3 to which are joyned, by a Cartilage, fo 
many Ofa nmcronata, one Sorter than another from the 
Head toward the Trunk. But the Vertebra, one lefter than 
another, from the Trunk towards the Head. 
The Vertebra of the Back, nineteen 3 that is, three fevens 
running one into another. Each of which hath three 
Prominent Parts, which are fharp, broad, and long 3 one 
perpendicular, and two that are tranfverfe , or at right 
angles. 
The Ribs 24, twelve on each fide. Seven of which, have 
each of them double Cartilages, that is, one after another, 
appendent to them. 
The fore part of the Sternum is plainly bony. The hin- 
der part, cartilaginous 3 fhaped like the Os Hyoides in a 
Man. 
The Vertebra of the Tail, are 34 3 or ( if you add the 
laft of the Trunk as common to both) 3 5 3 that is feven 
times feven. The firft fourteen, have each three Prominent 
Parts, like thofe of the Vertebra in the Back. The next 
nineteen, have only an upright Procefus. The laft of all, 
hath none. The firft 14, are double, in number to thofe 
of the Neck, the next 19, are equal to thofe of the Back 5 
the laft anfwers to the Head. To all the Vertebra of 
the Tail , except the laft , are alfo fubjoyned fo many
