20. The number of transits observed during the past year was 257, and the inclination of the axis was determined 29 times. As stated in the time-ball notice published in the Government Gazette on the 10th January, 1885, the time-ball is not dropped on Sundays or on Government Holidays. The covered wires in the reversing galvanometer were renewed and new zincs and manganese procured for the repair of the batteries. The time-ball was not dropped during the first half of the year owing to the absence of the First Assistant, whose duty it is to drop it. Since the 7th July, it was dropped by the engineer, who acted for him. From the 12th July till the 27th August inclusive it was handed over to the Public Works' Department for repairs, but the signal was given by dropping a flag. From the 16th September till the 8th October inclusive the ball was not dropped owing to the illness of the engineer in charge. On the 18th October, the ball was not hoisted as the wind was very strong. There were no failures in 1890.
