RECORD AND DISCUSSION 



In the first year, while in Baffin Bay, the velocity of the wind was greatest in 

 the months of February and March, and least in the months of June and July ; in 

 the second year, at Port Kennedy, it was greatest in October and November, and 

 least in March and April. In Baffin Bay, during 1857, '58, the N. W. and N. 

 winds blew with the greatest strength, and the S. W. and N. E. with the least; 

 whereas, in the following year, at Port Kennedy, it was the W. and N. W. wind 

 which blew strongest, and the N. and S. E. which blew with the least force. The 

 mean velocity of each of the eight winds is shown in the annexed diagram, which 

 contains also, for comparison, the velocity of the winds as observed at Van Rensse- 

 laer Harbor. 



The velocity of the wind being 

 only estimated at each place, the 

 apparently small velocities at Van 

 Kensselaer Harbor may, in a mea- 

 sure, be due to a different scale of 

 estimating, although the great num- 

 ber of calms seems to point to their 

 reality. 



We have next to consider the 

 relative frequency of each wind ; for 

 this purpose it is only necessary to 

 refer the number of entries, n, of 

 each wind, as used in the preceding 

 computation for the velocity, to an 

 equal number of hours of observation 

 for each month. This has been done 

 by simple proportion, and the num-
