Note. — The figures 1 -74 will be noticed at foot of column. In the first case, they indicate the difference 

 iDetween Back Sisht and Fore Sight ; in the second, difference of summation of Rise and Fall columns, 

 and are equal. The summation of the Rise column bein'; greatest, indicates a rise as sho\\Ti by the last 

 Reduced Level, 101 ^74, which is 1 ^74 greater than the first Reduced Level. This proves that the 

 Reduced Levels have been properly worked out, and is a check that should never be neglected.
