244 Rev. J. Macgarvie''s Thermometrical Observations 

 Table — continued. 



Hands and face affected by strong heat. Air in breeze 104% 

 in sun 114|°, in warm shade 104°. 



Beautiful clear sky to the west. 



Sun with a yellow tinge on the border. 



Continued to descend; lowest during the night about 7&°- 

 Highest rise 264° ni the shade; in sun, 4l|°. 



Sudden changes like these must try the strength of the strong- 

 est constitution. On the 18th of January, the change of tem- 

 perature, in falling from greatest heat, in one hour, was 4? 

 times greater than it had been on the 12th of January in four 

 hours ; and on the 21 st January, the rise from 6 to 2, in the 

 shade, was more than eight times that on the 12th January ; 

 and. in the sun^ was fourteen times greater I hat it had been in 

 the same space upon the same day. 



From these observations, imperfect as they are, (and to do 

 justice to meteorology would require more labour and unremit- 

 ting attention than one man can bestow), we draw the follow- 

 ing conclusions . 



It is somewhat singular that the hour of maximum heat in 

 this Table, and in the average, should occur about 3, or be- 

 tween 3 and 4 o'clock r. m., and that the average or mean tem- 

 perature should occur about 10, the precise hours that seem 

 to correspond with observations made in the northern hemi-
