NATURE NOTES 
close of the year. The tempera- 
ture falls with fair regularity until 
the 30th (the coldest day), whose 
average is 55'i°. A little relative 
cold is shown on the i ith(58’7°),and 
a little relative warmth on the 15th, 
16th, 17th, 22nd, 24th (s 6'4°), and 
28th (56’2°). On the 24th, in 1895, 
the maximum temperature reached 
the extraordinarily high point of 
87'3° ; but this date is outside the 
series of years dealt with. The 
maximum temperature was over 
8o'o° on six consecutive days, viz., 
from the 23rd to the 28th ; and the 
mean daily maximum of this period 
was 83‘3° ! It is doubtful whether 
similar cases of exceedingly high 
maxima happening so late in Sep- 
tember have occurredwithin “living 
memory” ; and these instances may 
well have been mentioned in my 
article on “Seasons” as affording 
remarkable exceptions to the rule 
that very few high maxima occur 
after September 22. Compare 
this hot weather with the wintry 
character of September 30th, 1905, 
on which day, at 8 p.m., the tem- 
perature at Oxford was only 45° ! 
Range, 6‘o°. Mean, 58'24°. 
October 
Commences with 55'4° (the highest 
value), followed immediately by 
a fall of I '3°. The temperature 
remains at about 54'o° till the 6th, 
when it is only S2‘8°. The next 
day it is again 54‘3°, followed by 
a drop of ri°, and this is suc- 
ceeded by a further diminution of 
i'6°. An increase is observaljle on 
the loth (52’i‘^). This is followed 
by falls of o‘3° and o'6°, after which 
the temperature is nearly sta- 
tionary for a week, with a mean of 
5o‘2°, the 1 8th, however, having a 
value of only 497°. 49'4° is reached 
on the 20th : then follow four 
nearly steady days with an average 
of 48’6°. 47'6° occurs on the 25th, 
and 47'5°on the 28th ; liut the 26th, 
27th, 29th, and 30th have values 
differing little from 47‘o’. The last 
day of the month is distinguished 
by a rise to 47'8®. The colclcst day 
is the 29th (467°). Range, 87". 
Mean, 5o'49°. 
Opens with 54'9°. The mean of 
the 31st is 47'o°. There is abso- 
lutely no check to the fall of tem- 
perature during the month ; but 
during the last five days the rate is 
slackened, and the average value 
of the five days is 47‘2°. Range, 
7 ' 9 °-
