30 RECORD AND REDUCTION 



perature is depressed 0°.5. The local configuration of the land, and the peculiar 

 situation of the port, may possibly affect the results deduced. 



The following recapitulation of results shows a tolerably fair agreement between 

 the localities— middle of Baffin Bay, Van Rensselaer Harbor, 1 and Port Kennedy.

Counting 8 from the north (or belonging to a true north wind), in the direction 

 east, south, etc., to 360°, the above tabular numbers can be expressed by the for-

 T= +o.9 sin (A + 320 ) + 0.4 sin (29 + 26 ) 



The second terms are of subordinate value; the first, or significant terms, cor- 

 respond upon the whole very close, considering the peculiarity of each station, in 

 reference to free exposure to the various winds. 



From the 4th number of the meteorological papers published by the Board of 

 Trade in 1800, I extract the following remark of Captain McClintock's : "The 

 Danish settlers at Upernavik, in Northwest Greenland, are at times startled by a 

 sudden rise of temperature during the deptli of winter, when all nature has been 

 long frozen; rain sometimes falls in torrents. It is called the warm southeast 

 wind." In reference to a warm northwest wind in Upper Baffin Bay, alluded to 

 in the same paper (p. iv), the above table for that locality shows that, although 

 this wind is warm in winter, it is considerably colder in spring, and also colder, 

 on the average, for the whole year.

 14th September, 1858, as soon as it appeared probable that we should winter at 

 Port Kennedy, I sunk a brass tube two feet two inches vertically in the ground, 

 and inserted a padded thermometer. The ground, at time of sinking the tube, 

 was frozen from six inches below the surface, and it was with great difficulty I 

 could get the tube sufficiently far down. The surface soil was similar to that

 of the Smithsonian Contributions to Knowledge. As explained elsewhere (and confirmed by Mr. Sonn- 

 ad Dr. Hayes), the trw direction of the wind was actually observed at Van Rensselaer Harbor; 

 hence, tin.' results given in the paper cited above required a corresponding change.
