registered was SS^.O, the mean of the highest being TG^.S, or 

 4«.8 higher than Bath. 



At Bath, there were only three days in the month, the 1 8th, 

 the 27th, and the 30th, on which the thermometer got as high 

 as 80"; while at Tunbridge,in Kent, there were five consecutive 

 days, the 1 3th to the 17th, on which it rose to 90" or more, 

 standing on the 17th as high as 95". 5.* The mean maximum 

 for these five days at Tunbridge was 92".!, the mean maximum 

 for the same five days at Bath being only 72". 5, or very nearly 

 20" less. Again, on the 20th of June, when the maximum at 

 Bath was 7 6". 2, at Greenwich it was 88", at Nottingham 88". 2, 

 at Derby and Bury St. Edmunds 86", at the Cambridge 

 Observatory 84". 9, while at four places in England the ther- 

 mometer rose to 90" or upwards that same day, viz., Staplehurst 

 and Gainsborough, where it was just 90", and Wigston and 

 Manchester, at each of which places it rose to 92". 



So much for Bath, in very hot weather, being hotter than other 

 places, as commonly though erroneously supposed. But we 

 come now to July, the hottest month in the year, in the long 

 run, and true to its character during the past summer of 1868. 



The mean temperature of July at Greenwich was 67".5, 

 being 6".l above the average of 97 years, which Mr. Glaisher 

 fixes at 61".4, and 8".l higher than the corresponding tempe- 

 rature of July, 1867. The only instance in which this month 

 had a higher mean temperature is said to have been the year 

 1859, when it attained to 68". 1. 



The mean temperature of July this last summer at Bath, 

 was 66".3,t being 1".2 less than at Greenwich. I observe,

t I am not quite sure that this ought to be so high, in consequence of a 

 manifest error in one or two of the entries in the daily Register. The mean 

 temperature of the month in my own garden, in Darlington Place, as calculated 

 from daily 9 a.m. observations, was only 6.3°. 7. In general there is very little 

 difference in the results obtained there and in the Institution Gardens. There 

 was scarcely any in respect of the mean of all the highest for last July.
