NB. When the result depends on less than 4 days' observations a star* is prefixed.
15. Mr. ROBERTS, of the Nautical Almanack Office, has harmonically analysed the hourly readings of tides published in my last volume and the results will in future be used in the tide-tables published anually for this port.
16. The number of transits observed in 1891 was 303, and the inclination of the axis was deter- mined 76 times. A new Standard Mean Time Clock was received in August last from Mr. JAMES BROCK, of 64, George Street, Portman Square, London. The works were very rusty when unpacked and the pivots had to be repolished. This was because it had not been oiled before packing in the zinc-lined case. The pendulum has the zinc and steel tubular compensation and a very heavy pendulum swinging in a large arc, which lessens the barometric coefficient, but there is an excessively large thermometric coefficient, the zinc being as usual too long. An Electric Chronograph has just been received from Sir HOWARD GRUBB, of Dublin, and is being unpacked. The Sidereal Standard Clock was taken to pieces and cleaned in autumn. It will be remarked that its gaining rate which had continued increasing for years, was changed into an increasing losing rate since it was re-started.
