OF OBSERVATIONS FOR TEMPERATURE.

this variation will disappear in the resulting average values. In the exceptional 

 case when no observations are recorded at 6 A. M. and P. M., the mean of obser- 

 vations at 4 and 8 A. M. and P. M. were substituted. For notes referring to the 

 observations of the winds, see the record or Part II of this discussion. The direc- 

 tions of the wind are " true." This method of investigation is less laborious than 

 that followed by me in a similar discussion of the temperature of the various winds 

 at Van Rensselaer Harbor. 



All results in Baffin Bay have been united, and a second group has been formed 

 from the observations at Port Kennedy. 



The seasons and localities for Baffin Bay, for which results were deduced, are as 

 follows : —

 Winter— Dec., 1858, Jan., Feb., 1859

This average position is nearly in the middle of Baffin Bay. 



The results in the last line, obtained after deducting 0°.2 from the preceding 

 line, show that the S. E. winds are the warmest, and the S. W. winds the coldest; 

 also, that during calms the temperature is lower. At Van Rensselaer Harbor, the 

 depressing effect of the calms amounted to 3°. 4. 



The following table shows the results for Port Kennedy : — 



The results for winds from the S. E., S., and S. W. are not very reliable, on 

 account of the scarcity of wind from these directions. At Port Kennedy, the 

 E. winds are the warmest and the N. W. the coldest; during calms, the mean tern-
