November. — 



" An early winter a svirly winter." — Old Proverb. 



Greenwich. — At the beginning of November the weather was 

 mild for a few days, then cold again, and thus alternated for two 

 or three days together, those of low temperature predominating. 

 During the month a remarkable change of temperature took 

 place ; the 10th, 11th, and 12th were of a wintry character, 

 with very low temperatures; whilst those of the 13th, 14th, 

 15th, and 16th were of very high temperatures, with heavy gales 

 of wind. Cold weather again set in on the 17th, and so con- 

 tinued until the end of the year. 



The mean temperature of November was 43°, being 0*6° higher 

 than the average of 98 years, higher than in 1868 and 1867, 

 when 41*5° and 41-4° respectively recorded, but lower than the 

 four iDreceding years, viz., 1863 to 1866.
