Here is a form of chart for keeping a record of the dentition. The significance of the letters is as follows:
- U. r.: upper right, i.e., the right half of the upper jaw.
- U. l.: upper left.
- L. r.: lower right.
- L. l.: lower left. (The fact must be borne in mind that in
- the first dentition there are twenty teeth.)

In this way we have an analytical and exact chart of the development of the teeth. Analogous tables are made for the second dentition, for the growth of the stature, for increase in weight, for certain physiological notes, etc. When the first period of growth is ended, the mother's note-books contain annual notes, like the following:
YEAR 190....
| Date | January | February | March | April | May | June | July | August | September | October | November | December |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Weight | ||||||||||||
| Stature |
Special annual diaries are now employed for keeping a minute record of maladies incurred, symptoms, treatment, etc.
