 during the same period.

A few obvious remarks occur on a comparison of the above tables. 



At Broughton Gifford during 1851 the means were lower for 

 every month, except December, when *19 higher. The maxima 

 were invariably lower. The minima lower every month except 

 August, when *15 higher. 



At Broughton Gifford during 1852 the means lower every month 

 except January, July, and October, when respectively '24, '01, *06 

 higher. But the means run each other very close this year, except 

 in August, when there is a difference of '53 in favour of G reenwich. 

 The maxima lower every month except February, April, May, and 

 August, when respectively *16, '40, "09, "01 higher. The minima 

 lower every month except March, April, July, September, October, 

 (nearly half the year), when respectively *21, '01, "12, *09, *06 

 higher. 



At Broughton Gifford during 1853, the means lower every month 

 except August, when '06 higher. Maxima lower every month ex- 

 cept August, when *51 higher. Minima lower every month except 

 January, March, May, July, September, October, December, (more
