g,4S,s ace Of sheer like that Of. theother
dime. tl6 animals, may be determined from
me- change and condition of the teeth
sphls IA certain up 70 the sixth year inclu-
Asivsly. and tolersbly sure hfer thl age
fThe sheer, like the OK, has eight ipcieors,
which areall situated in the lower Jaw, as
lin all minimizing animals. The Visible
mart of tie teeth which projects above the
gums 10 called The crown. At It's lower
p end. the crown becomes thinner and Is en-.
helope6in the gum This part is called
1.-The neck. The lower end OF the tooth.
(which tapers 10 a point and Is situated in
The socket is called tho root. All the
teeth are placed loosely in the sockets and
admit of more or less motion. The two
MIDDLE teeth are called tho tongs or gath
erers; the two on each side, the inner mid
die teeth; and the next on each side, the
outer middle teeth. The two external ones
are called the corner teeth.
In new born lambs the two gatherers
are just visible above the gums; after six
or eight DAYS, the two inner middle teeth
and after four or ak days more the two
outer middle teeth make their appearance
Six or eight days later the two corner
teeth may he seen so that In three weeks
after birth the sheep has its full compile
ment Of incisors. These teeth, called
milk.teeth, become longer and broader
and reach their full development al tht
end OF the first year. Their upper edge
or edge OF the crown, is somewhat
pointed
The milk.teeth remain from eighteen tc
twenty months, and then fall out, and arc
replaced by permanent teeth in the SAINT
order in which they appeared. The per
manent teeth differ from the milk.teeth by
the fact that the upper edge is not pointed
but straight and dull They are also
stronger and broader than the milk teeth,
and no longer milk.white, but yellowish.
When the sheep is eighteen or twenty
months old, the milkteeth fall out and are
replaced by two permanent teeth. The
animal is then called two.toothed.
When the sheep is three and half
years old, the two outer middle teeth fall
out and are replaced by two permanent
teeth.
When the sheep is four and half years
old, the two corner teeth fall out and are
replaced by two permanent teeth; and
now all have changed The animal is
then called eighttoothed.
In the sixth year the incisors undergo
different changes, from which the age Of
the sheep can be discovered with a tolera
BILE degree of certainty. The edges of
the crown gradually become niclsed and
dented, until they wear down almost to
the root This takes place in the same
order rs the changes of the teeth In the
seventh year both tongs or gatherers be
come notched at the edge Of the crown,
and in the eighth the nearest tw q become
notched, although a more distant one may
change instead, and the notches of the
gatherers become deeper In the ninth
year the crowns OF the gatherers and the
inner middle teeth are indented very
deeply, aud the other teeth also begin to
show notches. In the tenth and twelfth
years the crowns of all incisors are broken
aud worn, so that nothing but the roots
remain.
Under certain circumstances, produced
by diseases, food, etc, the wearing out O
the teeth sometimes varies considerably
from the above order Some sheep los,
the crowns of their teeth in the sixth anC
seventh years, while others retain then
unchanged until the eighth or tenth year,
or even longer. Vigor of health ant
body preserve the teeth.-DisedSeS O
