Hence the range of temperature between the warmest day, July 21, and the coldest, 

 January 9, is 25 0, 8. 



Mean Minimum Temperature. 



Table IX. shows the average minimum temperature of fifty years for each day of the 

 year. The monthly extremes are as follows : —

The extreme range is thus 21° '4, or 4° '4 less than the corresponding range between 

 the maxima. The mean maximum (Table VIII.) is above the annual average from April 

 26 to October 14, but the minimum (Table X.) does not get above the annual mean 

 until May 12, and remains above it till October 19. 



Mean Daily Range. 



The mean daily range of temperature is shown in Table XL, the values there given 

 being the differences between the mean maximum and minimum temperatures (Tables 

 VII. and IX.).
