The light was alwaysheld in the same position so that the error due to. themethod of reading must have been the same each time. Sincethis is the same for the two gauges and since it is theirdifference, rather than the reading itself, which is used,the effect of this upon the prohahle error may he , due probably to vibrations of the buildingcaused by the proximity of the engines in the University.
