days it fell to 32° and under ; on thirty days it rose to 70° 

 and upwards, but it never reached 80°. 



In regard to rain, the total of the year was 33"14 in., which 

 fell on 205 days. The driest month was March, when 1-26 in. 

 fell ; the wettest, October, when 6'51 in. fell. But as regards 

 days on which rain fell, there were fewest in September (ten 

 only), and most in December, when rain or snow fell on 

 twenty-five days ; so that the greater number of days on 

 which rain may fall in a month does not necessarily indicate 

 the greater amount of rain, for there may be a fall in any 

 one day which shall exceed in amount the fall of all the other 

 days in the month put together. The heaviest continuous 

 fall was on October 27th and 28th, when 1-65 in. fell in the 

 two days ; but the fall on April 25th was heaviest for any 

 one day, when 1"02 in. fell. There were only nine periods of 

 consecutive six days on which some rain fell each day. It is 

 remarkable that the heaviest falls were on February 25th, 

 March 25th, April 25th, June 24th, July 24th, and on the 

 28th of September, October, and November. The coincidence 

 of dates may not, however, indicate any law as to the fall of 

 rain. From the heavy faU of rain in October, we may look 

 for the rise and flow of the Bourne through the Caterham 

 Valley, a phenomenon which has been referred to on a 

 former occasion when the subject of rain was under discussion 

 by the Club. There was snow on March 21st and 22nd, and 

 sleet on March 26th ; and again on November 15th and 16th, 

 and on December 6th ; but the amount of snow that fell 

 during the year was but small. 



Wind. — There were gales the first week in January, but 

 they were not excessive. The remainder of January was of 

 note for the almost absolute calm which existed from the 

 12th to the 27th of the month, accompanied with some 

 amount of fog. In London and the suburbs the absence of 

 wind is almost sure to cause fog, especially the fog arising 

 from smoke. In February again, from the 1st to the 12th, 

 there was almost a total absence of wind ; all this time the 

 barometer stood very high. In March there were gales on 

 the 22nd and 26th from the N.W., the one on the 26th being
