To determine the
volume contained in a buret,
read the bottom of the meniscus at eye level.
Determine the volume using all certain digits plus one uncertain
digit. Certain digits are determined from the calibration marks on the cylinder.
The uncertain digit, the last digit of the volume,
is then estimated.
