Meteorology, Redhill, 1892. 
BAROMETER. 
Dealing with the monthly average, during the months of 
January and February the average pressure was below 30 inches. 
From March to July, both months inclusive, the average stood 
above 30 inches. August and October were under 30 inches. 
September, November, and December above 30 inches. It is 
to be borne in mind that my house stands, by Ordnance Survey, 
at an elevation of just 300 feet above the level of the sea, and 
consequently the barometer would stand about three-tenths of 
an inch lower with me than at the sea-shore. 
On 192 days the pressure reached to or was over 30 inches ; 
on 164 days under 30 inches, but on no day during the year 
did it fall below 29 inches. This result has not occurred for 
several years. 
THERMOMETER. 
On 49 days the temperature rose to 70° and over, but under 
80°, and on 102 days it fell to the freezing-point 32°, or below 
it. On six days only did the temperature fail during some 
part of the day to rise above 32°, namely on 9th and 10th 
January, on 16th February, and on the 2nd, 3rd, and 5th March. 
January, February, and March were cold. The mean tem- 
perature of March was only 35:70, more than 6 degrees below 
the average of the month. April was also cool, the average 
temperature eing 45°26, about 2 degrees below the general 
average of 50 years; but many days in the earlier part of the 
month were fine, cloudless, and genial. May and June were 
genial months. July was cool. August and September about 
the average temperature, but without any decidedly hot weather 
in August. Great difficulty and loss was incurred in getting 
in the harvest. October was a wet and cold month. November 
about an average, and December cold. 
The average temperature of the year was 46°86.
