The skull hath Braincs, as a kinde of Marrow, within it. The 
Backe-Bone hath one Kinde of Marrow, which hath an Affinitic with 
the Braine -, And other Bones of the Body haue another. The law-Bones 
haue no Marrow Seuered, but a little Pulpe of Marrow difthfed. Teeth 
like wife are thought to haue a kinde of Marrow diffufed, which cau- 
feth the Senfe and Paine : But it is rather Sinnew ; For Marrow hath no 
Senfe • No more than Bloud. Horne is alike thorowout ; And lo is the 
Naile. 
None other of the Hard Sub fiances haue Senfe,bm the Teeth; And the 
Teeth haue Senfe, not onely of Paine, but of Cold . 
But we will leaue the Enquiries of other Hard Subftances, vnto their fe¬ 
tter all places -'i And now enquire only of the Teeth. 
The Teeth are, in Men, of three Kindes : Sharpe , as the- Fore-Teeth ^ 
Broad,as thcBack-T eeth,which we call the Molar-Teeth,^ or Grinders^ And 
Pointed Teeth, or Canine^ which are betweene both.But there haue been 
forne Men, that haue had their Teeth mdiuided, as of one whole Bone 
withTome little Markein the Place of the Diuifion • as Pyrrhus had! 
Some Creatures haue Ouer-long, ox Out-growing Teeth, which we call 
Fangs, or T uskes-, As Boares,Pikes,Salmons, and Deg/ 3 thotigh leffe.Some 
Liuing Creatures haue Teeth agzint\ Teeth • As Men, and Horfes ; And 
fome haue r^,efpecially their Majler-T'eethfindemed one within An 
other, like Sawes-, As Lions-, And fo againehaue Dogs. Some Fijhes haue 
diuers Rowes of T eeth fin the Roofes of their Mouthes -, As Pikes, Salmons 
Trouts , &c. And many more in Salt-waters . Snakes and other Serpents 
haue VenemousTeeth -, which are fometimes miftaken for their Sting. 
No Beafi that hath Hornes, hath Fpper Teeth • And no Beafl, that 
hath T^aboue,wanteth them below : But yet if they be of the fame 
kinde, it followeth not, that if the Hard Matter goeth not intovpper 
Teeth, it will goe into Hornes -, Nor yet e conuerfo . For Doe's, that haue 
no Hornes, haue no Tpper Teeth. 
Horfeshmc, at three yeares old, a Tooth put forth, which they call \ 
the Colts Tooth-, And at foureyceres old there commeth the Mark-Tooth , 
which hath a Hole, as big as you may lay a Peafew ithin it-And that wea- 
reth fhorter and fhorter, euery yeare - Till that at eight yeares old, the 
Tooth is fmooth,aud the Hole gone 5 And then they fay. That the Marke 
is out of the Horfes Mouth. 
The Teeth of Men breed firft,when the childe is aboutayeere and 
halfe old : And then they caft them, and new come about jfeuen yeares 
old. But diuers haue Back-ward Teethe ome forth at Twentie, yea feme 
at Thirty, and Forty, gu&re of the manner of the Commiug of them 
forth. They tell a Tale of the old CounteJJe of Defmond , who lined till 
jfhe was feuen-fcore yeeres old, that fhe did Dentire , twice, or thrice 5 
Cafting her old Teeth, and others comming in their Place. 
Teeth arc much hurt by Sweet-Meats-, And by Painting with Mercury•, 
And by Things Ouer-hot • And by Things Oner-cold-, And by Rheumes. 
And the Paine of the Teeth, is one of the fharpeft of Paines .
