Note.—The Results are derived from Observations taken three times a day throughout the year; viz. at 9.30 a.m., 3.30 p.m., and 9.30 p.m. The self-registering instruments are read at 9.30 a.m. for 24 hours previous.
The Thermometers are compared periodically with a Standard, and the index errors computed.
The Wind Guage in use up to 30th September is not to be depended on, being of an inferior description. From the 1st October one of Dr. Robinson’s cup and dial Aneurometers has been used, which gives the velocity, and from it the pressure, of the wind at any time, and the miles of wind in the 24 hours; but does not record the maximum force.\n
- The greatest pressure of the Atmosphere observed was 30·578, on 3rd June; the least 29·034, on 18th May; the approximate range for the year, 1·544.
(a) On the 10th February.
(b) On the 1st August.
(c) On the 16th March.
(d) On the 11th December.
(e) On the 1st August.
(f) On the 21st October.
(g) On the 1st February, N.W. (for 9 months).
(h) On the 6th December (for 3 months).
