On the 1 0th it was again above 80°, standing at 82°, making 

 six days altogether in August on which it rose to or above 

 that point (80°). 



The mean temperature of the week ending August 8th, at 

 Greenwich, was 69°.8, being 7°.6 above the average of fifty 

 years. The mean temperature of the same week at Bath was 

 70°. 0, being a trifle higher. 



The mean temperature of the whole month at Greenwich 

 was 63°. 6, being 2°.9 higher than the average of 97 years ; 

 at Btith it was 62°. 6, exactly one degree lower than at 

 Greenwich. 



The mean of the highest for the whole month at Greenwich 

 was 75°.l ; at Bath, it was only 70°. 5, or more than 4i degrees 

 less. So that here again we see the chief difference between 

 Bath and Greenwich, in very hot weather, to be not so much 

 in the mean temperature as in the mean of all the highest. 



In September there was a return of hot weather during the 

 first week, the thermometer rising at Bath considerably above 

 80° on three consecutive days (5th, 6th, and 7th), standing on 

 the 7th at 87°.5, on which same day at Greenwich it rose as 

 high as 92°.l. At six other places in England it is stated to 

 have been above 90° that day (the 7th), though nowhere 

 higher than at Greenwich. Probably there is no former 

 instance on record, in which the thermometer rose so high 

 in September. 



The mean temperature of September at Greenwich was 

 60°.5, being 4°.0 above the average of 94 years ; at Bath it 

 was 59°.7 or 0°.8 lower. 



The mean of all the highest for September at Greenwich 

 was 7r.7 ; at Bath 69°.l, or more than 2 J degrees lower. 

 Here, again, we observe the difference between Bath and 

 Greenwich to be chiefly in respect of the high day tem- 

 peratures. 



And this further appears if, having gone over each of the
