The following table contains the individual results of the observed number of 

 vibrations in a given interval. The first column indicates left or right vibrations, 

 alternately ; the second gives the chronometer intervals derived from the preceding 

 means of each set of observations ; the third contains the correction for rate of 

 chronometer for the intervals ; the fourth the intervals corrected for rate and 

 expressed in seconds of mean time ; the fifth the corresponding number of vibra- 

 tions. These were obtained by working out for each of the 16 sets the number of 

 vibrations the pendulum gained Tipon the seconds of the chronometer in one hour, 

 thus confining our attention to the successive means of the preceding record and 

 their elapsed times, and subtracting the fraction of seconds of each from the preced- 

 ing mean (remarking whether the seconds are odd or even) we find, by taking the 

 differences of seconds and corresponding elapsed times collectively, the nvmiber of
