the front teeth which
before appeared; next the two lower front teeth, situated one on each
side of the central ones, which were the first to appear; and, lastly,
the two front grinders of the lower jaw. A pause until the eighteenth
month now ensues.

_Fourth_, Between the eighteenth and twenty-fourth months of life the
canine teeth cut through (the upper ones are called eye-teeth). Again a
pause until the thirtieth month.

_Fifth_, Between the thirtieth and thirty-sixth months the second four
grinders finally make their appearance.

This concludes the first teething. The child has now twenty milk-teeth.

We have mentioned that children are sometimes born with teeth. It is
also true that sometimes they never acquire any. Instances are on record
of adults who have never cut any teeth. Dentition has been known to
take place very late in life. A case is related, on excellent authority,
of an old lady aged eighty-five, who cut several teeth after attaining
that age.

APPEARANCE OF THE PERMANENT TEETH.

Between the fifth and sixth years of life the second dentition begins.
The front grinders are the ones first cut through. Between the sixth and
tenth years all the front teeth appear, followed by the canines before
the twelfth year. At this time the second grinders show themselves; and
finally, between the sixteenth and twenty-fourth year, the wisdom-teeth
complete the dental furniture of the mouth.

VACCINATION.

This operation, to which every infant should be subjected, is one of
great practical importance. The attempt has been made of late to shake
the public faith in its efficacy, and to revive the old fabulous stories
and foolish notions as to the production of serious affections of the
blood and skin in this manner. At the same time, the increasing
frequency and virulence of small-pox are becoming only too evident. We
therefore consider it our duty, in treating of the maternal management
of infancy, to lay some stress upon the necessity for vaccination as a
preservative of life and health. If observation and experience ever
taught anything, they have taught the protective power of this operation
against the most loathsome and one of the most fatal diseases that ever
afflicted the human race. And that mother who is careless and
indifferent in this matter neglects for her children a means of
preventing disfigurement and saving life, compared with which all other
means are scarcely worthy of mention.
