238 Meteorology. 



in the Institution Gardens, and a daily register has been kept 

 from the year 1865 to the present date. From time to time, 

 at the end of the decades, the results of these observations 

 have been tabulated and presented to the members of the 

 Bath Natural History and Antiquarian Field Club, and pub- 

 lished in their " Proceedings " (vols, i., iii., v., and vi.). On 

 these the following remarks are based : — " The observations 

 of the thermometer and rain-gauge have been carried on 

 during a period of twenty years — i.e., from the year 1866 

 to the end of 1885 ; those of the barometer relate to a 

 period only of eleven years. From the tables it appears 

 that the mean height of the barometer from 1875 to 1885, 

 corrected to temperature of 32° and sea level, was 29-976 

 inches. The highest barometer occurred on January i8th, 

 1882, when it was 30-978 inches ; the lowest was 28'337 

 inches on December 4th, 1876." 



The following Table will show the seasons at which the 

 maxima and minima occurred : — 



Spring. Summer. Autumn. Winter. 



Maxima . I ... o .. 2 ... 8 



Minima . i ... o ... 3 ... 7 



2 ... o ... 5 ... 15 

 So that, from these eleven years' observations, it appears that 

 the maxima elevations and minima depressions both occurred 

 in the winter months. 



The Thermometrical observations extended from the year 

 1866 to 1885 inclusive, with the following results : — Mean 

 temperature for twenty years, so°.s. The highest mean 

 temperature occurred in the year 1868, when it was 52°; the 

 lowest mean was in 1879, when it fell to 47°.s. The fol- 

 lowing. Table gives the mean temperature and the range of 

 the seasons :—
