Darlington Place, the maximum was 91°. At Greenwich, 

 however, there were foiu' days in July on which the tempe- 

 rature rose to 90° or upwards, and on that particular day (the 

 22nd) it rose to 96°.5, making a difference of six degrees. 

 That same day (the 22nd) it rose at Nottingham to 97°.3, and 

 at Wigston, in Leicestershire, to the extraordinary height of 

 98". Altogether there were, so far as I have been able to 

 ascertain, at least twenty places in England where the ther- 

 mometer rose on that day (probably the hottest of which we 

 have any record in this country) to a height varying from 90" 

 to 98°, the maxima at all the places, except one, being higher, 

 and most of them very much higher, than the maximum at 

 Bath. 



From all this I adhere to the conclusion I came to in a 

 communication I made to the British Association, when it 

 met at Bath in 1864, on the Temperature and Rainfall of the 

 Bath District. I stated in that paper my belief that, though 

 there is no great difference between Bath and other places in 

 England, lying eastwards in about the same latitude, in 

 respect of temperature, in moderate seasons or during mode- 

 rate weather, there is a marked difference when the weather 

 becomes of an extreme character, the difference being greater 

 in proportion to the excess of heat, if summer, or the excess 

 of cold, if winter, and amounting on an average to 5" in favour 

 of Bath.* 



The above results are all derived from the observations 

 made in the Institution Gardens. It has been sometimes 

 said that the locality is not a fair one, being low down by the 

 river, partially shut in by the Institution and other buildings 

 so as not to admit a free circulation of air, and tending unduly 

 to raise and depress the thermometer in times of extreme heat 

 and cold respectively. It is certainly not the best situation in
