Range of Temperature. 



The mean temperature, if taken alone, is not a safe guide to climate ; 

 for two stations may be identical as to their mean temperature, and yet 

 the climate be very different. It is for this reason I have constructed 

 Table III., giving the extremes of heat and cold during the period over 

 which the observations have extended. 



Table III. 

 EXTREMES OF TEMPERATURE. 



The IVth Table gives the range of temperature in each month, also 

 the mean daily range, and the greatest range that occured in any one 

 day.
