CLIMATOLOGY. 



lOQ 



This gives us for the sea an annual mean of 48 '4. We see 

 that here the difference between the extreme months is about 

 the same as that of the Thirsk springs and lower than that of 

 the monthly means of the air by about 10 degrees, the 

 extreme cold of the Winter and the extreme heat of the Summer 

 being both cut off, as is the case to a lesser extent with the air 

 at the sea-side as compared with what it is at an inland station. 

 It will be seen that the sea is conspicuously warmer than the 

 air in Winter, conspicuously colder in Summer.

 seven stations either actually within the limits of North Yorkshire 

 or not far from its borders.

It will be seen that the distribution of the fall over the different 

 seasons of the year is very irregular. Out of the seven northern 

 stations the least rainy month in five cases is February, in one 

 March and in one May ; the most rainy in three cases October, 

 in two September, in one July and in one August. At Green- 

 wich the Winter and Spring have about the same amount of
