AB  - 1. The calculations necessary for calibrating the Waller gas balance for ether are given in detail. Tables are appended to simplify the corrections needed for variations in barometer, temperature, water vapor, and alcohol content of ether. It is probable that the corrected tension is accurate to within ± 0.2 mm. 2. By means of the Waller gas balance, thus calibrated, the Connell anaesthetometer has been tested and it was found that the tension of ether delivered by our apparatus was on the average 2.1 mm. too high, the maximum error being + 3.3 mm. The Connell apparatus adjusts itself to atmospheric conditions if the ether delivery is expressed in tension and not in percentages.
