[PLASKETT-DELURY] THE SOLAR ROTATION 67 
There are of course similar tables of residuals for the 24 plates 
measured at each of the latitudes 30° and 60°; but it is only necessary 
to give the mean numerical and algebraic residuals for each of these 
latitudes the same as has been done at the foot of the preceding table. 
The following table contains a summary of the mean residuals 
for each line at each of these latitudes and then the final mean residuals 
for the 72 measures of each line.
