48 



much above the average as that of May, which Mr. Glaisher 

 states to have been exceeded in only two instances, the years 

 1848 and 1833, going as far back as 1771. " The mean 

 temperature of April at Greenwich was 48". 1, being 2". 2 higher 

 than the average of 97 years ; that of May, 57''.3, being 4".8 

 higher than the same average." 



At Bath, the mean temperature of April was 47''.7, being 

 0''.4 lower than at Greenwich ; — the mean temperature of May 

 was t)6°.2, being also lower than that of Greenwich by rather 

 more than a degree. It is also observable that in no instance 

 at Bath * did the maximum temperature during May reach to 

 80", while at Greenwich it rose to above 80" on two, if not 

 more occasions. On the 19th of May, when in the Institution 

 Gardens the thermometer was never higher than 79", it rose to 

 87". 6 at Camden Town, 87" at Greenwich, Staplehurst, Boston, 

 and Gainsborough, 86" at Manchester, 85" at Selborne and 

 Bury St. Edmunds, and at some height between that and 80" 

 at various other places in England. At Wigston, in Leicester- 

 shire, it is recorded to have been even as high as 91".f 



In Jime, the temperature continued advancing beyond the 

 average. The mean temperature of that month at Greenwich 

 was 62".0, being 3".9 higher than the average of 97 years. At 

 Bath, it was 61".5, half a degree less than Greenwich. A more 

 marked difference was observable between Bath and Green- 

 wich, as well as between Bath and several other places, 

 in respect of the maximum temperature attained on 

 particular days. At Bath, the maximum never got above 

 80".8, the mean maximum for the month, or the mean of the 

 highest, being 7l".5. At Greenwich the highest temperature 



* Here and in other places, when speaking of the temperature of Bath, unless 

 otherwise mentioned, I speak in reference to the observations made in the 

 Institution Gardens.
