not only plac'd each Tooth in a diflinft Cavity 

 of the Jaw-bone, as it were in a clofe, ftrong, 

 and deep Socket, but has furnifli'd the feveral 

 Sorts of Teeth with Holdfafts fuitable to the 

 Strefs, that by reafon of their different Offices 

 they are to be put to , and therefore, whereas the 

 Cutters and Eye-teeth have ufually but one Root 

 (which in thefe laft nam'd is wont to be very 

 lojig) the Grinders, that are employed to crack 

 Nuts, Stones of Fruit, Bones, or other hard Bo- 

 dies, are furniih'd with three Roots, and in the 

 upper Jaw often with four, becaufe thefe are 

 pendulous, and the Subftance of the.Jaw fome* 

 what fofter. 



VIII. The Situation of the Teeth is moft con- 

 venient, viz, the Molar es or Grinders behind, 

 neareft the Center of Motion, becaufe there is a 

 greater Strength or Force required to chew the 

 Meat than to bite a piece -, and the Cutters before, 

 that they may be ready to cut off a Morfel from 

 any folid Food, to be tranfmitted to the Grin-- 

 ders, ' 



IX. It is remarkable that the Jaw in Men, 

 and fuch Animals as are furnifh'd with Grinders, 

 hath an oblique and tranfverfe Motion, which is 

 neceffary for chewing and comminution of the 

 Meat, which it is obferv'd not to have in thofe 

 Ani/nals that want the Molares.
