Mr. Ford has communicated to me the number of days when 

 the thermometer at York, in the shade, sunk to or below 32 in 

 each of the seven following years. 



The temperature of York compared with that in other parts of 

 the county presents a variety of results interesting to all lovers 

 of knowledge and valuable to invalids. 



The mean annual temperature of York is not materially dif- 

 ferent from that of other places in the county not much more 

 elevated above the sea. 



The following table exhibits a few of these results, in the com- 

 paratively low region of the centre of the county : 



York 48-2, Brandsby 47'47, Malton 47'65. 



Nor is the case very different on the sea-coast, where Keying-

Or in hollows of an elevated region. At Halifax the mean 

 temperature appears to be 48-3 (1827-28). 



It is in the unequal distribution of the temperature in the dif- 

 ferent months that we must look for the principal peculiarities 

 of local climate. 



For this purpose we may compare the mean temperature of the
