In the following table is given the number of times different errors occurred in the years 1925 and 1926:—

Error of Time Ball 1925 1926 0'3 sec. or less 631 0'4 12 0'5 8 0'6 5 0'7 3 0'8 1 2 0'9 1 650

The error of 0.8 sec, which occurred on February 18th, was owing to accidental over-correction of the Mean Time clock.

The Mean probable error of the time ball in each month of the past five years is given in the following table:—
