THe WEATHER OF 1907. 67 
neutralised by the prevalence of haze and mist, and the absence 
of drying winds, so that little in-gathering could be done, and 
it was followed by the deluges of October, which proved to be 
the wettest month of the year, with a rainfall of 7.53 inches— 
more than double the average—and 25 days on which it fell. 
The result was that much of the grain was destroyed, especially 
in late places, and not a little so seriously damaged as to be of 
little value. 
The facts regarding the dry and wet bulbs are as follows :— 
Mean dry bulb for the year, 47.2 degs.; mean wet bulb, 44.9 
degs.; temperature of the dew-point, 41.7 degs.; relative 
humidity (saturation 100), 83. It will be observed that the mean 
temperature of the dry bulb for the year, ascertained from the 
observations taken at 9 a.m. and 9 p.m., differs by only two- 
tenths of a degree from the mean temperature of the year, ascer- 
tained in a different method—by the addition of the mean maxi- 
mum and the mean minimum, the highest and lowest of the 24 
hours, divided by 2. The one is 47.2 degs., and the other 47.4 
degs. 
With regard to thunderstorms, I find that I have noted 10: 
days on which thunder and lightning, or, in one or two cases, 
thunder only, were observed. One in February, three in April, 
one in May, three in June, one in July, and one in September— 
that is 10 days in all, which is rather in excess of the usual 
number. Of course, there may have been others which I have 
failed to notice or record, and I have noted eleven instances on 
which hail showers occurred, mostly in the same months. There 
was a very brilliant display of aurora borealis on the 9th of 
February, and it may be worth while to observe that this was 
followed on the next day by hail showers, and on the day 
following that by a pretty severe thunderstorm during the night. 
Whether there was any connection between these phenomena I 
am not prepared to say. 
As to the wind directions, the south-west, as usual, showed 
the greatest number of days, viz., 78; the next was north-west, 
with 61; the west, with 54; the south-east, with 50; the north- 
east, with 46; the east, with 28; the north, with 22; the south, 
with 17 ; besides a few more on which it was calm or variable.
