FREQUENCY OF THE SEVERAL WINDS (YEAR). 



The following are the mean results for the whole island : 



We learn from them that, in the year 1851, the wind blew, on the 

 average of the entire year, most frequently from between S. W. 

 and W., and least frequently from between N. E. and E. The 

 same thing holds also for the summer half-year, the point of maxi- 

 mum frequency being, very nearly, W. 8. W., and that of mininmm 

 frequency E. N. E. In the winter half-year the point of maximum 

 frequency is more nearly S.W., that of the minimum being as 

 before. The ratio of the numbers representing the greatest and 

 least frequency is greater in winter than in summer.
