September. 
The first three days were very fine, Avitli light S.W. winds, and 
high barometric pressure, caused by a large anti-cyclone lying over 
the south of England; the unusually high pressure of 30.436 was 
recorded at 9 i^.in. on the 1st. The barometric pressure fell from 
30 inches on the 5th to 29.784 at 9 p.m. the Gth, and fluctuated 
slightly until the 8th, when a further fall was recorded from 
29.709 at 9 a.m., to 29.477 at 9 a.m. the 9th. This decrease of 
jiressure was caused by a barometric depression travelling across 
the north of England in an easterly direction, and causing a strong 
S.W. wind on the 9th. From the 10th to the 22nd the weather 
was generally cloudy, the winds light and variable, the temperature 
generally below the average, and frequent, though slight, oscillation 
in the barometer. The barometer fell quickly from about 29.900 
on the 22nd to about 29.400 on the 24th, attended by the 
unusually large fall of 1.28 in. of rain on the 23rd. The 
barometric pressure increased quickly, and the 25th, 26th, and 
27th were fine days. The last three days were cloudy and 
showery, 0.49 in. of rain falling on the 28th. The total rainfall 
for the month was 1.01 in. above the average. 
Note— N o ohservatioiis of the barometer and thermometers were 
recorded between the 20th and 30th ; the averages of the barometric 
pressure and of the temperature are taken from readings on the first 19 
days of the month. 
October. 
The weather during this month was cold and cloudy ; the day 
temperatures were 2.5 degrees below the average, and the night 
temperatures 0.5 deficient. The barometric in’essure increased 
from about 29.800 on the 1st, to about 30.300 on the 5th, and 
remained unu.sually high and steady from the 5th to the 13th, 
owing to a large anti-cyclone which -was stationary over England 
during those days, and caused unusually calm, but dull, cloudy 
weather. The high barometric reading of 30.532 was recorded at 
9 a.m. the 12tb. The 14th, 15th, and 1 Gth were showery, with 
N.W. winds, and slight barometric oscillation. The barometer 
fell (piickly from 30.150 at 9 p.m. the IGth, to 29.G55 at 3 p.m. 
the 17th, but rose to 29.903 at 3 p.m. the 18th. A further fall to 
29.257 at 9 a.m. the 20Lli was recorded, attended by a strong
