The President, Mr. W. H. Tyndall, read notes on "Meteoro- 

 logy, Oxford Eoad, Eedhill, 1884." 



In noticing the Meteorology for the past year, regard may 

 first be had to the Barometer. For eight months in the year 

 the average stood above 80 in., and for four months it was 

 below that average. The observations were made at 8 a.m., 

 and indicate the height of the barometer at Eedhill at an 

 elevation of just 800 ft. above sea-level. The maximum of 

 the year was 80'63 in., on October 5th; the minimum observed 

 at 8 a.m. was 28*88 in., on December 20th, but it did fall to 

 28-64 in. about 9 p.m. on January 26th ; this was during a 

 heavy gale from the S.W. For 220 days the barometer 

 reached 80 in. and upwards ; for 144 days it was under 30 in. 

 and above 29 in. ; for two days it fell below 29 in. It will be 

 remembered that there were 866 days in 1884, A very rapid 

 fall of the barometer occurred on December 20th, followed by 

 a rapid recovery. 



On the 18th, at 8 a.m., the barometer stood at 80-01 in.

the fall being 1-18 in. in two days, the rise 1-08 in. in one 



day. A heavy gale accompanied the variation. 



Thermometer. — There was no severe cold during the year, 

 and no day in which the thermometer did not rise above the 

 freezing-point in some part of the twenty-four hours. January, 

 usually the coldest month in the year, was remarkable for 

 having only one frosty night, and then the thermometer fell 

 only to 81° ; this was on January 1st ; the average tempera- 

 ture of January was 42-73°, more than 5^° above the average 

 of the month. Febi-uary was also comparatively warm, the 

 average of the month being 41-89°, or more than 2° above the 

 mean as observed for fifty years ; February was a colder 

 month than January ; there were ten fr-osty nights in the 

 month. March was also slightly above the average, being 

 43-24° against the mean of 42° over fifty years ; there were 

 five frosty nights in March, the lowest temperature being 

 24*50° on the 2nd. April was cold; there were six frosty
