| Abstract: | - 1.1. By the use of a new piece of apparatus, a procedure is described that allows more accurate determination of gas volume in manometers than has been previously possible.
- 2.2. The standard error of the mean of ten readings of gas volume for a single manometer was found to be ±7 × 10−5 ml.
- 3.3. It is possible to obtain repeat readings rapidly and with very little spillage of mercury.
- 4.4. This method also allows easy removal of any air trapped by the rising mercury.
