THE TEETH. 199
all the incisors fully up, until it is five years old. It will be seen,
however, in this mouth of four years, that the two central pairs are
beginning to be worn down at the edges, and that in a flat direction,
or somewhat inclining towards the inside.
THREE YEARS. PAST. FOUR YEARS. PAST.
At five years old, the teeth are all fully grown, but this mark has
extended over the whole set, and all the teeth are a little flattened
at the top ; while on the two centre ones there begins to be a dis-
tinct darker line in. the middle, bounded by a line of harder bone.
From this time the age for a year or two can only be guessed at,
and a great deal will depend upon
the manner in which the animal
is fed. The beast most out,
and compelled most to use his
incisor teeth, will have them
worn farthest down. As a i
general rule, but admitting of
many exceptions, at seven years
old, this line is becoming broad-
est and more irregular in all of
the teeth; and a second and
broader, and more circular mark
appears within the centre of the
former one, the most distinct in
the central, or two central pairs
—and which at eight years has
spread over the six central inci-
sors.
