Full text: Bacon, Francis: Sylva sylvarum

Natural Hiſtory; is rather Sinew; for Marrow hath no Senſe, no more then Blood. Horn is
alike throughout, and ſo is the Nail.

32.1.

750.

None other of the hard ſubſtances have Senſe, but the Teeth; and the
Teeth have Senſe, not onely oſ Pain, but of Cold.

32.1.

751.

But we will leave the Enquiries of other Hard Subſtances unto their ſeve-
# ral places, and now enquire onely of the Teeth.

The Teeth are in Men of three kindes, Sharp, as the Fore-teeth; Broad, as
the Back-teeth, which we call the Molar-teeth, or Grinders; and Pointed-teeth,
or Canine, which are between both. But there have been ſome Men that
have had their Teeth undivided, as of one whole Bone, with ſome little
mark in the place of the Diviſion, as Pyrrhus had. Some Creatures have
over-long or out growing Teah, which we call Fangs or Tusks; as Boars,
Pikes, Salmons, and Dogs, though leſs. Some Living Creatures have Teeth
againſt Teeth, as Men and Horſes; and ſome have Teeth, eſpecially their Maſter-
teeth, indented one within another like Saws, as Lions; and ſo again have
Dogs. Some Fishes have divers Rows of Teeth in the Roofs of their Mouths; as Pikes, Salmons, Trouts, & c. and many more in Salt. waters. Snakes and other
Serpents have venemous Tee@h, which are ſometimes miſtaken for their
Sting.

32.1.

752.

No Beaſt that hath Horns hath upper-teeth; and no Beaſt that hath Teeth
above, wanteth them below. But yetif they be of the ſame kinde, it follow-
eth not, that if the hard matter goeth not into upper-teeth, it will go into
Horns; nor yet è converſo, for Does that have no Horns, have no upper-
teeth.

32.1.

753.

Horſes have, at three years old, a Tooth put forth which they call the
Colis-tooth; and at four years old, there cometh the Mark-tooth, which hath
a hole ſo big as you may lay a Peaſe within it; and that weareth ſhorter
and ſhorter every year, till that at eight years old the Tooth is ſmooth,
and the hole gone; and then they ſay, That the Mark is out of the Horſes
Mouth.

32.1.

754.

The Teeth of Men breed firſt; when the Childe is about a year and
half old, and then they caſt them, and new come about ſeven years old. But
divershave Backward-teeth come forth attwenty, yea, ſome at thirty, and
forty. Quare of the manner of the coming of them forth. They tell atale
of the old Counteſs of Deſmond, who lived till ſhe was Sevenſcore years
old, that ſhe did Dentire twice orthrice, caſting her old Teeth, and others
coming in their place.

32.1.

755.

Teeth are much hurt by Sweet-meats, and by Painting with Mercury,
and by things over-hot, and by things over-cold, and by Rheums. And the
pain of the Teeth, is one of the ſharpeſt of pains.

32.1.

756.

Concerning Teeth, theſe things are to be conſidered. 1. The preſerving
of them. 2. The keeping of them white. 3. The drawing of them with
leaſt pain. 4. The ſtaying and eaſing of the Tooth-ach. 5. The binding in
of Artificial Teeth, where Teeth have been ſtrucken out. 6. And laſt of
all, that great one, of reſtoring Teeth in Age. The inſtances that give any
likelihood of reſtoring Teeth in Age, are, The late coming of Teeth in
ſome, and the renewing of the Beaks in Birds, which are commaterial with
Teeth. Quare thereſore more particularly how that cometh. And again,
the renewing of Horns, But yet that hath not been known to have been
provoked by Art; therefore let tryal be made, whether Horns may be pro-
cured to grow in Beaſts that are not horned, and how; and whether they
may be procured to come larger then uſual, as to make an Ox or a Deer
