TABLE II. 



Constants of the frequency-curves. 

 Daily-means of air-temperature. 



From these results of the calculation il is evident that in contrast 

 to most frequency-curves, the D, deviations from the simple ex- 

 ponential law for the frequency-curve of the daily-means of the air- 

 temperature are slight and may be regarded as being within the 

 limits of the errors of observation. 



In order to investigate how far the calculation agrees with the 

 observation, the numbers of Table 1 for the months of January and 

 December are taken together as being the most asymmetrical. The 

 numbers obtained in this way are indicated in Table III by 

 (observed). 



The constants of these curve are: 



M= 4.469 0° 



h = 0.2403 



D, = + 0.01764 



D t — 4- 0.00130
