G-reenwich. — The average mean temperature of June was 62°, 

 or 3 "9° higher than the average of the preceding ninety- seven 

 years. The month of June was of high temperature, but was 

 greatly exceeded in the year 1846, when it was 65'3°, or 3-3° 

 warmer. The other instances in June of higher temperature 

 than in June of the present year, back to the year 1771, were in 

 the years 1775, 1781, 1818, 1822, 1842. The highest of them 

 was 62-9° in 1842 and 1818 ; the lowest 62-5° in 1781. 



The mean temperature for the three months ending June was 

 55-8°. For the same period in 1775 it was 55-5° ; in 1822 55° ; 

 in 1844 55-1°; in 1846 55-7; in 1848 55-3; and in 1865 56-2°; 

 so that the only instance in ninety-eight years of higher tempera- 

 ture in the corresponding quarter of 1868 was in 1865. In the 

 latter year the temperature in April was 52*3°, being higher than 

 any other April on record. 



The other years since 1771, when the mean temperature of 

 the three months ending with June exceeded 54° and was less 

 than 55°, were 1778, 1779, 1788, 1798, 1811, 1826, 1833, 1834, 

 and 1858. 



It will be interesting to compare the mean temperature of the 

 longer period, viz., February to June. The mean temperature
