9. As stated in the Instructions for making Meteorological Observations, etc.,' meteorological instruments forwarded by observers who regularly send their Registers to the Observatory, are verified here free of cost. During the past year 4 thermometers wer- verified. In addition several hundred barometers and aneroids on board ship were come pared with our standard.

10. In 1905 the number of transits observed was 374. The axis of the transit instru- ment was levelled 176 times, and the azimuth and collimation errors, which are less liable to variation, were determined 35 times by aid of the meridian mark. During Mr. PLUMMER'S absence on leave since 8th March, these observations have been made by Mr. FIGG.

The Standard Sidereal Clock by Dent was cleaned on November 30th. The other clocks have had no alterations effected during the year.

The errors of the Time-ball are given in Table II. The ball is not dropped on Sundays nor on Government holidays. There were no failures during 1905. The ball was not hoisted on six occasions, viz. :- on March 20th and 27th on account of thunder- storms; on April 17th the line was out of order, the earth connection in the Police basin having parted; on August 30th a strong gale was blowing; and on August 31st an September 1st the line was under repair owing to damage caused by the gale of 30th August. The ball was dropped successfully 292 times in 1905. The probable error was in January ± 0.17, in February ± 0.85, in March± 0.56, in April ± 0.33, in May ± 0.16, in June ± 0.19, in July ± 0.25, in August ± 0.17, in September ± 0.10, in October

± 0.13, in November ± 0.11, in December ± 0 ̊.14.
