is with them we bite bread and apples, where the first business is to
cut. It is with the same teeth that lazy little girls bite their thread,
when they will not take the trouble to find their scissors; and, by the
by, this is a very bad trick, because by rubbing them one against
another in this manner we wear them out, and, as you will soon discover,
worn-out teeth never grow again.

The next sort are those little pointed teeth, which come after the
_incisors,_ on each side of both jaws. You will easily find them;
and if you press against them a little, you will feel their points.
If we call the first set the knives of the mouth, we may call these
its forks. They serve to pierce whatever requires to be torn, and they
are called _canine_ teeth, from the Latin word _canis_, a dog, because
dogs make great use of them in tearing their food. They place their paws
upon it, and plunging the canine teeth into it, pull off pieces by a
jerk of the head. Look into the mouth of papa's dog: you will recognize
these teeth by their rather curved points. They are longer than the
rest, and are called fangs. I do not know, after all, why they have
chosen to name these teeth _canine_, as all carnivorous animals have the
same fangs, and in the lion, the tiger, and many other species, they are
much more developed and sharper than in the dog. In cats they are like
little nails. However, the name is given, and we cannot alter it.

The last teeth, which are placed at the back of the jaw, are called
molars, from the Latin word _mola_, which means a millstone.

You must be prepared to meet with several Latin words as we go on; but
never mind; this will give you the opportunity of learning a little
Latin, and so of keeping your brother in order, if he ever looks down
upon you because he is learning Latin at school. Formerly, all learned
