fifth to twelfth year, 80 to 90; thirteenth to
twenty-first year, 75 to 80; twenty-first to sixtieth year, 70 to 75; in
old age, 75 to 85.

INFANT RECORDS.--A record should be kept by the mother of every child
which would embrace exact data as to weight, diet, size, development of
mental power, teeth, ailments, sickness, pains, etc., with dates and any
information which would aid in recalling exact conditions. Such records
are of the utmost value in a number of ways. They help in giving
suggestions as to diet, general health, and mental qualities of the
child in question, and they aid in furnishing what physicians call "past
history," which past history has a very valuable significance in
estimating the character and importance of sickness during later years.

Such a record is also of importance in comparing a child's development
with what is regarded as standard development, and also with the growth
and development of other children in or out of the family.

If a child should thus be found to fall seriously below the standard and
yet not appear actually sick, a very thorough and routine investigation
should be instituted to discover if possible the cause. Some error might
thus be detected which might seriously affect the child's future growth
and well-being.

The date of the closing of the soft spot on the baby's head should be
noted, and if it is still open, when it should be closed, it might mean
that the child has a serious brain condition. The soft spot should close
between the eighteenth and twenty-fourth months. The family physician
should be notified if the soft spot is open later than the second year,
as he may want to investigate the cause.

Should the child be unusually backward in walking, and when it does so
should limp and feel pain in the knees, it should be examined for any
symptom of hip joint disease, of which these are the earliest signs.

If the child complains of so-called "growing pains," keep in mind that
these are rheumatic and may need attention. There are no such pains as
actual "growing pains," that is, pains caused by the child growing.
