Congress, will, I believe, when compared with the observations made 

 by previous expeditions on the inland ice, furnish some idea of the climate. 



We carried two normal thermometers with mercury, and one spirit 

 thermometer. The last, however, proved useless, so that I have on 

 some days been unable to make any record beyond the fact that the 

 temperature was less than Ч- 37°. (At temperatures below this figure 

 the mercury cannot be relied on). 



Velocity of the wind has been noted as estimated, in metres per 

 second. 



Clouds noted as estimated, the figure 10 indicating sky entirely 

 overcast.
