TEMPERATURE. 



From the subject of Barometrical observations I pass on to 

 consider that of Thermometrical observations. I went so fully 

 into the subject of temperature, considered generally, in my 

 former paper on the Bath Climate, that it is hardly necessary to 

 do more here than to combine the results of ten years' further 

 observations with those of the first decade. The period, therefore, 

 now to be considered is one of 20 years, commencing with 

 1866 and ending with 1885 ; and there is the less occasion, also, 

 for going much into detail from the results varying but little 

 in the two cases. I shall confine myself chiefly to a statement of 

 results as regards the mean temperature of the whole term of 

 years and the temperature of the seasons. 



The mean temperature of the first nine years will be found in 

 my former paper. The mean temperatures of each of the eleven 

 last years is as follows : — 



The mean temperature of the whole series of twenty years is 

 exactly the same as that of the first ten, which in my former 

 paper is set at 50°'5. The variation also between the two 

 decades, taken separately, does not amount to one-tenth of a 

 de<T:ee ; so we may fairly consider the mean temperature of 

 Bath, at least in the lower part of the town, to have been 

 determined with tolerable correctness. 



The year of highest mean temperature in the whole series is 

 1868, when the mean rose to 52o. The year of lowest mean
