[nORW. POL. EXP. 



Taking the means for the 3 (or 2) years for each month, we obtain the 

 following Mean temperature for each day of the year. 



Tm = -19-°19 + 18-°715. sin (267°9-'5 + m) + 2-° 147. sin {102°l-'8 + 2m) 

 which gives 



Minimum — 35-° 94 January 25tli- 



Maximum + l-°60 July 15t!i. 



Annual Range 37"° 54. 

 The curve computed from this formula apparently makes the epoch of the minimum 

 too early, and does not correspond to the flatness of the real curve in the summer months. 

 I therefore prefer the results given above in the text, as being in closer accordance 

 with the results of observation.
