until the night of the 20th. “The [weekly] Summary of 
Changes in the Weather over the British Islands and their 
Neighbourhood! from the 11th to the 17th of October” informs 
us that throughout this week the pressure over our islands and 
their neighbourhood has been mainly cyclonic; from the 11th 
to the 14th the type of gradient was northerly, but on the 15th 
and 16th it was easterly. Two well-marked depressions ap- 
peared in addition to the one which was passing away from us 
on the morning of the 11th. The second of these depressions, 
which had become a shallow subsidiary disturbance on the 15th 
over the south of France, moved westward from our area during 
the 16th; and as this system passed away, an anti-cyclonic 
“col” was formed over our islands, uniting an anti-cyclone 
over France with another off our extreme western coasts. With 
this anti-cyclone the cold northerly winds which had prevailed 
changed, and on the 16th the weather became very fine over 
England, the temperature rose, and the wind became a south- 
easterly breeze. The summary for the 18th to the 24th of 
October informs us that ‘the distribution of pressure over our 
islands and France was anti-cyclonic, with light or moderate 
south-easterly and easterly winds, till the 20th, then cyclonic 
and complex, with northerly winds.” 
The second movement extended from the 8th to the 12th of 
November. Regarding the meteorological conditions, the sum- 
maries tell us that previous to the 8th the weather had been 
changeable and unsettled generally, and the distribution of 
pressure mainly cyclonic, with westerly, north-westerly, and 
southerly winds. From the 8th to 13th the pressure system 
over North-Western Europe was anti-cyclonic, with light 
(easterly in south, south-easterly in west, and southerly in the 
north) breezes. On the 13th, however, a large and somewhat 
deep depression advanced from the Atlantic, and spread quickly 
over all North-Western Europe, with gradients for south-westerly 
and westerly winds. 
Thus we had the two chief movements of the autumn ushered 
in by and concurrent with anti-cyclonic conditions, preceded by

North-Western Europe, from Bodo and Haparanda to Corunna and Toulon. 
They are based: upon numerous Continental returns from the area indicated, as 
well as from all parts of our own islands.
