Anemometer and Wind Vane.—A Robinson hemispherical 
cup anemometer and wind vane are placed on the top 
of a ladder erection at a height of 17 feet above the ground. 
Owing to the somewhat sheltered position, the results are 
only of comparative value, although, for a town, the situation 
is about as good as could be obtained. ; 
Sunshine-—A Campbell-Stokes sunshine recorder gives a 
continuous record of bright sunshine whenever the sun 
shines. Owing to smoke from the city, fully 10 per cent. 
of the possible sunshine is lost, even on practically cloudless 
days, it being a well-known fact that the instrument ceases 
to record when the sun shines through smoke-haze, or thin 
cirri-form clouds. 
Rainband.—Observations on the thickness of the rainband 
in the spectrum of sunlight are generally made thrice 
daily, viz., at 9 A.M., noon, and 3 P.M.; an extra observation 
being made at 6 P.M. when the state of the light permits. 
The instrument used is one of Hilger’s direct vision 
spectroscopes. 
Miscellaneous Observations—A Stephanome, invented by 
Professor Tait, is employed for the angular measurements of 
halos, coronz, etc. Since last year (1892) one of Aitken’s 
dust counters and a koniscope have been added to the stock 
of instruments, regular observations being at present in 
progress. In addition to the above, non-instrumental 
observations of the direction and force of the wind, amount, 
form, and species of cloud, etc, are made daily. The 
instruments, of which the foregoing is a brief description, 
have, with few exceptions, been compared with the standard 
instruments at the Kew Observatory, an additional check 
being the annual inspection of the station by Dr Buchan, 
in the autumn of each year. 
REMARKS ON THE METEOROLOGY oF 1892. 
January.—Dry and sunny weather were the prominent 
features of the meteorology of this month. During the first 
three weeks, temperature was uniformly low, and _ slight 
showers of snow and soft hail were of frequent occurrence.
