 Table III the monthly mean temperatures are given in form of departures 

 from the corresponding means of the years 1900-1909 and in Figure 4 

 the curve A represents these departures graphically. Curve B shows the

succession of consecutive yearly means and C gives the values of the 

 differences between the monthly mean maxima and minima. This last 

 curve indicates the changes of the range of the diurnal variation of 

 temperature. On the average, the lowest value is observed in July and 

 the highest in March. The respective mean values for the different 

 months are: 8'°.32, 8°.72, 8°.95, 8°.72, 7°.78, 7M8, 6°.99, 7°.53, 7°.97,
