warm, as were the 10th and 11th, but to a less degree ; from the 
15th every day was warm and above its average mean temperature. 
The atmospheric pressure was below its average from the 16th to 
the 22nd, and above it on every other day. The fall of rain was

mean temperature of the 28th was 16° below its average, and it was 
the coldest day in October for many years. The atmospheric 
pressure till the 30th was above its average, with the exception of 
two or three days. The fall of rain was small. 
The weather in November was geneially fine and mild till the

10° above their averages. On the 25th the temperature fell quickly, 
to the 28th, when the mean temperature at Blackheath was 20°'2, 
being 21°-4 below the average, and the mean depression of tempera-
